A New York City police captain has been fined $50,000 by the Police Department after admitting that he improperly solicited information from two detectives about grand jury testimony concerning police corruption in a Queens precinct. Department officials indicated that four or five other officers and detectives from that precinct - the 110th -are also expected to be brought up on departmental charges stemming from a two-year investigation by the state's special anticorruption prosecutor, Thomas A. Duffy Jr. Last month, the investigation led to the indictment and arrest on criminal charges of seven police officers, including two sergeants, who were or had been assigned to the 110th Precinct. As part of the agreement that resulted in the captain's guilty plea to the administrative charge, other departmental charges were dropped. The 53-year-old captain, Harold W. Coleman, a member of the police force for more than 27 years, was allowed to retire on a pension of at least $30,000 a year.

After posting unsettling increases in May and June, the July consumer price index, due Tuesday from the Labor Department, should bring welcome relief. Thanks to easing energy prices and mortgage interest rates, analysts say the price index, which galloped along at double-digit rates late this spring, rose at about a 5 percent annual rate last month.

SALEM CENTER CRICKETS chirped in the warmth of a mowed field out behind Salem Feed and Supply. Across Route 116, two men moved slowly in the summer sun among the vehicles at the town of North Salem garage. The playground near St. James Episcopal Church on the east side of Route 124 was empty. Inside the feed store, baled hay stood in the corner, and sacks of cracked corn and ''16% sweet feed'' climbed the low walls behind the pot belly of a Magnum cast-iron stove.

The paired cities that face each other across the 1,960-mile border between the United States and Mexico are being battered by economic chaos because of the devaluations of the Mexico peso this year. On the Mexican side, residents of cities like Matamoros, accustomed to shopping in the United States for anything from shoes to milk, have found their purchasing power there cut by nearly two-thirds. So they are staying home to shop, and they find themselves competing for goods with Americans who are scurrying across the border to take advantage of the power that the dollar has gained in the Mexican marketplace. Meanwhile, the mercantile economies of American border cities like Brownsville, Matamoros's sister city across the Rio Grande, are in a state of shock. Brown Seeks Disaster Aid In California, Gov. Edmund G. Brown Jr. has appealed to President Reagan for economic disaster aid for San Diego and Imperial Counties because of the devaluation.
