REPORT OF THE STATE ENTOMOLOGIST I914 I29 



d Fifth vein forked, the sixth a branch of the fifth 



e Fifth vein close to the posterior margin and uniting therewith near 

 the basal half; palpi triarticulate ; terminal clasp segment short 



Bryocrypta KiefE. 

 ee Fifth vein not close to the posterior margin, uniting therewith near 

 the distal fourth; palpi quadriarticulate 



/ No supernumerary vein at base of subcosta; claws toothed; terminal 

 clasp segment greatly produced, slender 



Didactylomyia Felt 

 // Supernumerary vein at base of subcosta; claws simple 



Liebeliola Kieff. & Jorg. 

 dd Fifth vein simple, the sixth wanting 



e Palpi quadriarticulate Johnsonomyia Felt ^ 



ee Palpi biarticulate Colomyia Kieff- 



cc Wings usually very long, narrow, the crossvein almost at right angles to 

 costa 

 1^ d Fifth vein forked, the sixth a branch of the fifth; terminal clasp segment 



W short, swollen, the claws usually simple Colpodia Winn. 



W dd Fifth vein simple, not reaching the wing margin 



*■ Clinophaena Kieff. 



ddd Fifth vein simple, the sixth wanting (fossil) 



Paleocolpodia Meun. 

 aa Crossvein parallel or nearly so with costa and apparently a continuation of 

 the third vein 

 b Four long veins, the fifth simple, the sixth free 

 c Fifth vein not obsolete basally 



d Distal portion of the abdomen not recurved dorsally 



e Pul villi longer than the unidentate claws; 16 or more antennal seg- 

 ments; ovipositor biarticulate Asynapta H. Lw. 



ee Pul villi shorter than the simple claws; 14 antennal segments; ovi- 

 positor triarticulate Clinorhytis Kieff. 



dd Abdomen slender, the distal portion recurved dorsally; claws toothed, 



the lobes of the ovipositor biarticulate ...Ruebsaamenia Kieff. 



cc Fifth vein obsolete basally; abdomen greatly produced, at least three 



times the length of the remainder of the body Dicerura Kieff _ 



hh Three long veins, the sixth a branch of the fifth or wanting 

 c Fifth vein forked 



d Circumfili of the male not forming long loops or bows as in the 

 Itonidinariae 

 e Palpi quadriarticulate 

 / Antennal segments of the male greatly produced, or at least with a 

 distinct stem 



1 The absence of circumfili compels the reference of this genus to the Hetero- 

 pezinae, though the superficial wing and antennal structures would place it here. 

 It has therefore been included in the key simply to facilitate identification.
