usual angle toward the base of the tegmen. The metopidium is not pro- 

 duced any higher than is absolutely necessary to cover the mesothorax 

 and metathorax. 



In the species common to Kansas the dorsum is transversely rounded 

 and punctate. Van Duzee states that some species of this genus have 

 the dorsum carinated and sinuated. 



The color of the species of the genus Vaiiduzea is mottled with dark, 

 either dark bi-own or black, with whitish or light oblique vittae. The 

 pi'othorax is pilose, the legs dark brown to black, with light hairs. The 

 tegniina, except in the costal region, is transparent, the nervules with 

 black or bi'own dotted lines. The tip of the limbus is infuscated.

Color reddish brown, verging to black. There are white or light 

 yellow markings or vittae, an oblique spot joining the lateral margin, 

 and a line just before the posterior process. Sometimes there is a small 

 white spot on the dorsum almost concurrent with the spots on the sides. 

 The pronotum bears no procephalon or crest and is smoothly rounded 

 transvei'sely. The metopidium rises slightly from the head and then 

 curves gently backward to the dorsum, which is slightly arcuated to the 

 posterior process. The metopidium (in cephalic view) is broad, with 

 short, obtuse suprahumerals. Head and body and legs dark and pilose. 



Length 5.1 to 4..5 mm. 



Habitat: Galveston and Brownsville, Tex.; Douglas and Congress 

 Junction, Ariz.; Kansas City, Mo.; Kansas City, Kan.; Morton, Clark, 

 Douglas, Stevens. Seward and Haskell counties, Kansas. 



According to the determination in F. H. S. collection, there are two 

 species common to Kansas, V. arquata and V". vestita. Van Duzee sepa- 

 rates these species by the costal region of the tegmina. V. arquata has 

 the costal cell coriaceous and punctured for nearly its whole length; 

 V. I'estita has the costal areole or cell coneolorous, sparsely punctate 

 near the base. If this classification be true — and I have every reason to 

 consider it such — then there is but one species in the F. H. S. collection, 

 as all the specimens agree with V. arquata. In Van Duzee's description 

 of V. arquata he states that the suprahumerals are more prominent than 

 in V. arquata. With this description as a basis, the specimens here can 

 not be V. vestita, as there is no ascertainable diiference in the promi- 

 nence of the suprahumerals. 



Genus EntyUa Germ. 



This genus has received a considerable list of sjmonyms, which I 

 append at the close of the description of species. It is widely distributed 

 east of the Rocky Mountains, and some species occur in considerable 

 numbers, the writer having found extensive colonies in Kansas and 

 Vermont. 



The metopidium of the prothorax rises in a high elevation to form a 

 distinct procephalon, almost perpendicular or sloping slightly forward 

 on its cephalic edge. This procephalon is greatly compressed and ex- 

 tends rectilinearly caudad for a short distance, descending suddenly and 

 abruptly into a deep sinus smoothly curved at the base. This sinus
