than that of the type of Eiplwsoma. Moreover, insularis lacks all of 

 the propodeal carinae except the two transverse carinae and the 

 basal portion and sometimes the apical portion of the median carinae. 

 In the present arrangement it would fall in the typical subgenus.

In addition to the key characters and those mentioned by Ashmead 

 in the original description, the following are perhaps worthy of note. 

 Clypeus in female very broadly rounded, barely half as long as wide, 

 in male subtruncate for its entire width; face medially elevated, 

 slightly narrower than frons; diameter of lateral ocellus subequal to 

 postocellar line and slightly greater than ocell-ocular line; thorax 

 rather densely punctate, the punctures of metapleura smaller; scutel- 

 lum impunctate; apical carina of propodeum arched in middle; radius 

 before middle of stigma; petiole of areolet shorter than rest of first 

 intercubitus; nervulus interstitial; hind coxae except at apex black.

There are four females of tliis species in the National Museum, 

 two from Coleta, xilabama, (H. H. Smith), and one each from College 

 Park, Maryland, and Washington, District of Columbia (both col- 

 lected bv Frederick Knab). 



Ch'^peus broadly subtruncate, strongly convex, two-tliirds as long 

 as wide; malar space half as long as basal width of mandible; face 

 elevated medially, equal in width to frons; diameter of lateral ocellus 

 equal to postocellar line and twice as long as ocell-ocular line; thorax- 

 sparsely punctate, propodeum and metapleura very obscurely so; 

 propodeum with both transverse carinae, but median carinae devel- 

 oped only before basal and behind apical carinae, sometimes absent 

 in latter position, apical carina medially curved backward; radius 

 before middle of stigma; petiole of areolet equal to or longer, in one 

 specimen much longer, than rest of first intercubitus; nervulus 

 interstitial; hind coxae testaceous and yellow, more or less blackish 

 within. 



EIPHOSOMA (EIPHOSOMA) TEXANUM Cresson. 



Eiphosoma texanum Cresson, Trans. Amer. Ent. Soc, vol. 4, 1872, p. 176. 



Malar space slightly shorter than basal width of mandible; clypeus 

 strongly rounded at apex, two-thirds as long as broad; separation from 

 face weak ; face distinctly narrower than frons, not strongly elevated
