154 AV. n. ASHMEAD. 



EIICOII.IDEA n. g. 



This genus is at once distinguished from all other genera in the 

 Eucoilime by two ])ai-apsidal grooves on mesothorax, which converge 

 and meet at about t\vo-thirds their length posteriorly, thence to base 

 of the scutellum as a delicate carina. 



The cup of scutellum is very large, elliptical, greatly elevated 

 above a line with the mesothorax, and separated from it by a trans- 

 verse arcuate groove ; its upper surface flat, but slightly pressed in 

 on the disk. Wings as in Eucoila. The antenn.'c in 1 is 15-jointed 

 and very distinct from all others in the genera of the Eucoilince iu 

 that the third joint is twice as long as the fourtli, strongly curved 

 and excised, the following joints are about equal in length, a little 

 more than twice as long as wide or long moniliform, the terminal 

 joint being slightly smaller than the preceding one. Abdomen as in 

 Eucoila, but annulus at base without pubescence. Two species in 

 our fauna has been discovered as follows : 



49. Eucoilidea loiigicoriiis n. sp.— "J,. Length .07 inch. Black, pol- 

 ished ; antenna red, longer than body ; legs, excepting femora at tips, honey- 

 yellow, femora black ; wings hyaline, pubescent; veins pale. 



Desci'ibed from one specimen captured at large. 



50. Eu«*oili«lest caiisicleuKi!^ n. sp.— 9 . Length .09 inch. Differs from 

 longiconiis principally in having all the legs dark red and the veins in the wings 

 yellowish. 



Hnb. — Canada (Abbe Provancher). 



Subfamily Figitin.e. 



THYREOCERA n. g. 



This genus is allied to Figites and Eucoila, and is founded upon 

 one 9 specimen. The antennas are 1.3-jointed as in Figites and 

 Eucoila ; the thorax smooth, with two parapsidal grooves ; the scu- 

 tellum diflers from those of other genera in being smooth, polished 

 and having a. sninll erect club on its disk posteriorly near the tij), bifo- 

 veate at base. The abdomen is com|)res.sed, somewhat simihir to 

 Meldiiips Haliday, in shape, all the segments being visible, but dif- 

 fers in that the third joint is inuch longer than the second and is 

 not ornate at base, without either a j)ubescent girdle or a striate an- 

 nulus ; the petiole is short, stout, striate. The wings have a hmg, 

 triangular, closed marginal cell, and the marginal nervure and second 

 transverse cross each other, forming a triangular areolet.
