more closely related to each other than to other species of the genus, 

 and all are easily separated from their congeners. In 1S95, Brunner, 

 in his Monographic der Pseudophylliden, assigned four species to this 

 genus, two being from Mexico and one from Colombia. Lifaros- 

 celis cooksotii is at once distinguished from two of these species by its 

 smooth face. It is probably much more closely related to the remain- 

 ing species, L. nlgrispinis Stal, but is readily distinguished by the 

 fewer spines on the under side of the fore and middle femora and by 

 the acute unemarginate subgenital plate and straight ovipositor of the 

 female.

Butler's type was from Charles, so there is no doubt as to the forms 

 to which his name applies. True, he had some immature specimens 

 from Albemarle, and some or all of these may have belonged to another 

 species. Brunner's specimen 

 was from Charles and its iden- 

 tification may be considered 

 certain. As Scudder's speci- 

 mens (except a single immature 

 one from Indefatigable) came 

 from Albemarle, they probably 

 belong here, though they are 

 somewhat larger than my speci- 

 mens from the same locality. Fig. 38. Liparoscelis cooksoniBuiXtv^ 

 and the ovipositor is more than female, ovipositor and end of a bdomen. 

 proportionally longer; how- 

 sever, this may be due to the fact that the method of measuring 

 this organ used by Scudder and myself are different. .He measures 

 a straight line from the tip to the junction of the upperand lower 

 laminae where they leave the body; in other words he measured 

 the chord and I the arc. If the curvature was measured, and es- 

 pecially, in this case, if the keel of the lower lamina was measured, 

 the length here given would be increased two or three millimeters.
