UHLER ON INSECTS. 401 



Length 6^-8 millimeters. Width between the tips of angles of the 

 pronotum 4^-0:| millimeters. 



From Eastern Massachusetts, near Charlestown, Audover, and Lynn. 

 Beaten bj^ myself from small oaks at Egg Harbor, N. J., in August; 

 and, during the same mouth, also obtained from bushes near Manitou, 

 Colo.; Maryland, June 28 and September 30, on Carya; also in Georgia. 



This beautiful little species resembles the genus Euschistus in that 

 part of the group represented by E. trist'ujma Say. It also forms a 

 connecting link between the Asopincc and the group represented by the 

 genus JEiiscliistus, having the lobate head and narrow rostrum of the latter, 

 with the general structure of the former. As it roams so widely, and over 

 a multitude of plants and trees, we believe it to be carnivorous, like its 

 brethren of the genus PocUsus. The place of its occurrence near Mani- 

 tou was in the valley, where the surface was well overgrown with small 

 oaks and a great variety of bushes, adjacent to the Fountain Creek. 



Subfamily HALYDIN.E. 



Prionosoma Uhler. 

 P. podopioides. 



Prionosoma podopioides Uhler, Proc. Entom. Soc. Phila., 1863, ii, 364. 



A single specimen occurred to me while sweeping the bushes near 

 Golden, Colo., in August. Specimens have been sent to me from Denver 

 by Benjamin H. Smith. It inhabits Arizona, Nevada, and California. 



Subfamily PENTATOMIN.E. 



Neottiglossa Kirby. 



1. X. undata. 



Pentatoma undata Say, Hetei'OiDt. New Harmony. 8, No. 17 ; Comi^lete Writ- 

 ings, i, 319, 17. 



Common in Massachusetts, Illinois, Minnesota, etc. One specimen 

 occurred to me in Clear Creek Caiion in August. 



This species was previously referred by me to the Neottiglossa triline- 

 aid Kirby. The latter, however, seems to be a species sufficiently dis- 

 tinct from the preceding to justify its separation. 



2. X. trilineata. 



Pentatoma (Xeottir/lossa) trilineata Kirby. Fauna Boreali-Amer., iv, 276, pi. 6, 



fig. 6. 

 Aelia trilineata Dallas, British Museum List Hemiiit., i, 224, No. 6. 



Inhabits Dakota, British Columbia, Canada, Nebraska, and the re- 

 gion of the Mackenzie Eiver. 



It differs from the preceding in being larger and more robust and 

 blunt anteriorly, the head entirely black and more coarsely punctate, 

 the venter more widely black, and the femora much more invaded with 

 black. A single specimen was sent to me from the vicinity of San 

 Francisco by James Behrens. 



This species has much the appearance of Aparijyhe intermedia Fieber 

 of Europe, but it does not belong to that genus.
