This is a summary of recent congressional actions not reported elsewhere in The Post. HOUSE Military Construction

The House approved, 354 to 38, legislation authorizing the Pentagon's construction budget for fiscal 1986. The House voted to trim the $9.55 billion recommended by the House Armed Services Committee to $9.2 billion. The Senate has approved an $8.8 billion authorization, lower than President Reagan's $10.31 billion request. The fiscal 1985 figure was $8.4 billion. (HR1409, Oct. 16) Arts and Humanities Funds

The House approved, by 349 to 57, legislation to reauthorize the National Endowment for the Arts, the National Endowment for the Humanities and the Institute of Museum Services through fiscal 1989. For fiscal 1986, the bill would authorize a total of $328.5 million, including $167 million for the NEA, $140 million for the NEH, and $22 million for the institute. The levels reflect the fiscal 1985 appropriation levels plus $400,000 to cover pay increases already approved for the endowments, and $3 million to cover an increased NEA funding for the Public Broadcasting System and National Public Radio. (HR3248, Oct. 10) SENATE HUD Funds

The Senate passed, 76 to 9, a bill to appropriate about $54 billion for the Housing and Urban Development Department and 17 other agencies for fiscal 1986. The bill would earmark $25.7 billion for the Veterans Administration, $11.9 billion for HUD, and $7.6 billion for NASA. After adding $570 million for revenue sharing and $100 million for veterans' care, the Senate approved a 1.1 percent across-the-board cut in many agency budgets, including HUD and the VA. The House version, passed July 25, would appropriate $56.3 billion for the agencies. (HR 3038; Oct. 18) Agriculture Funds

By an 81 to 14 vote, the Senate passed a $28.5 billion agriculture appropriations bill for fiscal 1986. The measure survived two efforts to cut funding by more than $1 billion for rural development, domestic food and certain other programs. The bill contains about $10 million more than the version approved by the Senate Appropriations Committee. The measure now goes back to the House, which has passed a bill that is $8.3 billion more than the Senate version. (HR3037, Oct. 16)
