D. platyrhynchus Osb. — This unique form, before known from 

 Iowa and Nebraska, has been taken on the plains and well up 

 into the foot hills of Colorado. The larvae have been found in 

 Aristida clumps on plains which gives it a new food plant. In 

 the foot hills it was taken where both Elymus, its known food 

 plant, and Stipa were abundant, but as no larvee were found it 

 was impossible to locate it as on either grass. 



D. vanduzei Osb. and Ball. — This species was described from 

 northwestern Iowa and thought to be from Sporobolus, but this 

 season the -larvas and adults have been found quite commonly 

 in clumps of Aristida purjyurea in western Kansas and Nebraska 

 and as far west as Greeley, Colo. This is the first capture of 

 the male, which is strikingly different from that of p)latyrhyn- 

 clius and is described as follows: 



Male — slightly smaller and narrower than the female, head simi- 

 lar in shape, slightly shorter, elytra as long as the head and prono- 

 tum very narrow, appendix present, abdomen long and narrow, 

 the last two segments visible beyond the elytra, beyond which the 

 remarkably elongated style-like pygofers extend for about four 

 millimeters, as long as the rest of the abdomen. Color — darker 

 than the female, the tip of the vertex broadly fuscous, elytra and 

 abdomen dirty brown. 



Hecatus lineatus uhl. 



E. fennestratiis Uhl. 



This species is now known from New Jersey, New York, 

 Iowa, Kansas, Nebraska and Colorado, always found in low 

 places where the "Slough grass," Spartina cynosuroides, on 

 which it feeds, is found. 



Spanbergiella vulnerata uhl. 



S. lynchei Berg. 



S. mexicana Baker. 



This species ranges from the southern United States through 

 the West Indies and Mexico to Argentine, S. A. It is some- 

 what variable in the shape of the head, as are all the species 

 with foliaceous vertices, which has led Mr. Baker to resurrect 

 one synonym and create another. He quotes Signoret as say- 

 ins" " this might well be the S. vulnerata " and goes on to say 

 that Berg took this "suggestion " as final. If Mr. Baker had 

 been able to read Signoret himself instead of depending on a 

 translator, he would have found this, also, "Having received 

 the type from the author we confirm this synonomy " a " sug-
