tion. Two of these I took on the dry prairies, at the Leyden mines, 

 near Denver, Col. The other was taken at Boulder, Col., and 

 kindly given to me by Rev. M. Wirtner. One of the Denver speci- 

 mens is immature and is colored alniost exactly as described by Dr. 

 Uhler under C. albipejinis Say in the Hemiptera of Colorado, p. 10. 

 In form and markings renormata closely resembles basalis Germ, 

 from South America, but it is only about one-half the size of that 

 species, and it is well distinguished in other respects. 



CorimelaMia Sayi nov. nom. {albipennis Sa,y, preoc). 



While looking over the very excellent collection of Hemiptera in 

 the Agricultural College at Fort Collins, Col., last summer, I was 

 delighted to find a tine pair of these insects that had been captured 

 in the foot hills about thirty miles northwest of the College. Prof. 

 Gillette very generously gave me one of these specimens for study. 

 Comparing this with the description of albipennis given by Uhler 

 in the Hemiptera of Colorado, it becomes evident that the specimen 

 before Dr. Uhler was not albipennis at all, but the immature form 

 of renorviata, as suggested by him. The present specimens corre- 

 spond with Say's description in every detail. The head is rather 

 long and well rounded before, with the sides very feebly sinuated ; 

 antenme soiled yellow, with tlie apical joint longer than in renor- 

 mata. Pronotum flatter than usual in this genus, strongly narrowed 

 before, blackish, with the basal disk broadly castaneous, and the 

 broad lateral margins white and calloused, humeral angles rather 

 prominent. Scutellum sliort and broad, apex regularly rounded, 

 base deeply excavated at the sides ; color castaneous, remotely })unc- 

 tured with blackish, and with a blackish impressed area at each 

 basal angle. Coriaceous portion of the elytra when closed very 

 broad, white, with a short black longitudinal streak placed behind 

 the middle and near to the inner niargin. Venter very dark cas- 

 taneous, with the edges interruptedly thickened and rufous; breast 

 black; legs brown, tarsi pale. The punctuation of the upper sur- 

 face is rather shallow and almost concolorous on the disk of the 

 pronotum and scutellum. In form this species most nearly resem- 

 bles ciiiata. 



These individuals and another sent by Prof. Gillette to Prof. 

 Herbert Oshorn and recorded by him in Ent. News, iv, p. 91, 1893, 

 and Pioc. Iowa Acad, of Sciences, vol. i, pt. 4, p. 121, 1894, are, 

 so far as I can learn, the only known specimens. Unfortunately
