NEW DIPTERA IN THE IT. S. NATIONAL MUSEUM. By D. W. COQUILLETT,Custodian, Section of Diptera. In the course of identifying- ttie New Jersey diptera for Dr. J. B.Smith's excellent list of the insects of that State, ]Mr. C. W. Johnson,curator of the Wagner Free Institute, of Philadelphia, encounteredquite a series of specimens belonging to obscure groups which he wasunable to identify within the limited time allowed him for this pur-pose, and consequently submitted them to the writer for study. Mr.Johnson permitted the retention for the U. S. National ]SIuseum collec-tion of specimens pertaining to species not already represented therein,the only conditions being that the data from the labels be sent him,together with the names of the known forms and manuscript names ofsuch as were believed to be new to science. As these manuscriptnames have now been published it is deemed advisable to publishdescriptions of these species and thus render permanent the nameswhich would otherwise have no value. i\.ccorcl 'ngly, these descriptionsare offered herewith, together with a number of those of other formsencountered when identifying specimens for correspondents, or whilestud3'ing and comparing the Museum collection. These make a totalof 2 genera and 71 species.Family MYCETOPHILIDvE.BOLITOPHILA MONTANA, new species.Dark brown, the base of the third antennal joint, peduncle of thehalteres, coxte, femora and tibite light yellow, sides of mesonotumlargely brownish yellow, mesonotum polished; wings hyaline, stigmaelongate oval, gray; auxiliary vein reaches only slightly beyond middle,between humeral cross vein and base of third vein, anterior branchof third vein terminates in the costa, fourth vein at its base coalescingfor a short distance with the upper branch of the fifth near its base;length, 4.5 mm.
