110 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 51 



geniculation is shorter than head height. Palpi absent. Two orbi- 

 tal bristles in female, none in male. Some extra bristles outside the 

 frontal row, but these do not form a definite second row except 

 anteriorly in some males. No ocellar bristles. Claws of female 

 short, those of male as long as last tarsal joint. 



The genus differs from Trichophora by having the abdomen elon- 

 gate, subcorneal or subcylindrical, reaching nearly to end of wings. 

 Trichophora has abdomen much shorter than wings and rounded. 



SPANIPALPUS, gen. nov. 



This genus is proposed for Trichophora miscelli Coquillett. It 

 differs from Copecrypta in possessing a strong pair of ocellar 

 bristles ; proboscis long and slender, much longer than head height ; 

 abdomen considerably widened (female). Male not known. Fe- 

 male with two strong orbital bristles; only one row of frontal 

 bristles ; inner pair of vertical bristles very long and strongly 

 curved, decussate, reclinate. Apical crossvein normal, not crooked, 

 evenly bowed in near origin ; apical cell widely attenuate on terminal 

 portion, widely open. A distinct wrinkle at origin of apical cross- 

 vein. 



DEOPALPUS, gen. nov. 



Differs from Spanipalpus only as follows: No ocellar bristles. 

 Two very definite rows of frontal bristles on each side of frontalia. 

 No orbital bristles (male), claws of male not elongate. Parafacials, 

 parafrontals, and cheeks evenly and thinly pilose with rather long 

 fine black hairs. Parafrontals not metallic or blackish, silvery 

 white. Venation and proboscis like Spanipalpus. Abdomen about 

 like Copecrypta. The head bristles, like those of all the rest of the 

 body, are strong. The inner frontal rows are decussate, extending 

 only half way back between base of antennas and vertex. The outer 

 row on each side is composed of lightly reclinate bristles of nearly 

 equal strength, nearly as strong as the vertical bristles. Both rows 

 descend well below base of antennae, the outer row slightly lower 

 than the inner and to base of third antennal joint. Two facio- 

 orbital bristles as strong as the frontal bristles. Facial plate strongly 

 produced below. Second antennal joint elongate, about as long as 

 third. Second aristal joint strongly elongate, slightly geniculate. 

 Cheeks nearly equal to eye height. Type, the following species : 



Deopalpus hirsutus, sp. nov. 



One male. Meadow Valley, head of Rio Piedras Verdes, about
