NEW SPECIES OF GALL MIDGES— FELT. 



207 



subapical and shorter than the portion of the basal clasp segment 

 extending beyond the point of insertion. Ovipositor short, fleshy, 

 the lobes quadriarticulate, setose. 



Type of the genus. — Eocincticornia austrdlasiae, new species. 



The circumfili indicate an affinity with the American Cincticornia 

 and European Polystepha, though the reduction of the palpi, the 

 greatly developed circumfili and basal clasp seg- 

 ment prevent its association with either of these 

 genera. 



EOCINCTICORNIA AUSTRALASIAE, new species. 



The peculiar form described below was received 

 through the courtesy of the United States Na- 

 tional Museum and labeled Perth, West Australia, 

 G. Compere, collector, 798. It is such a striking 

 species that there should be no difficulty in recog- 

 nizing it from the following characterization. 



Male. — Length, 2 mm. Antennae nearly as 

 long as the body, naked, dark brown; 14 sessile, 

 cylindric segments, the first short, obconic, the 

 second disk-like, the third and fourth free, the 

 fifth with a length about 2J times its diameter, 

 with a basal whorl of very short setae and the 

 entire surface covered with a fine reticulation of 

 low, stout circumfili, there being about 18 very 

 irregular transverse fili on a segment; terminal 



segment not reduced, with a 

 length three times its diameter, 

 obtuse apically. Palpi; first 

 segment short, irregular, the 

 second with a length about 2J 

 times its diameter, stout, the 

 third Dearly three times the 

 length of the second, irregular, 

 slender. Mesonotum dark red- 

 dish brown. Scutellum and 

 postscutellum dark yellowish 

 brown. Abdomen very dark 

 brown, almost black. Wings 

 hyaline, the membrane almost 

 free from hairs, subcost a uniting 

 with costa at the basal third, 

 the third vein heavy, joining 

 the margin just beyond the wing apex, the fifth vein obsolescent dis- 

 tally, strongly curved and joining the posterior margin at the basal 

 third; the anterior branch discernible only as an almost imperceptible 

 line. Halteres fuscous yellowish. Coxae dark yellowish brown. Legs
