AMERICAN HEMIPTERA. 41 



]\Iy matefiul in this species represents the toliowinii' h)calities: Col- 

 orado Ball), Ogden, Utah, and Salt Lake City, Utah (Browning), 

 Moscow, Idaho (Aldrich), and Gallatin County, Mont. (Cooley). 

 Prof. Oshorn has kindly sent me a Colorado specimen determined 

 as coiignta that agrees very closely with mine. 



Peiitatonia (dilorocliroa; ligalit Say. ' Cimex rnfomiird'ntatns Kouvh.i 

 This species averages larger than any of the preceding. The 

 elytra and sometimes the scutelluin and pronotuni are well sprinkled 

 with smooth, pale points; the antennte are entirely black or with 

 the basal joint only green, and the venter is strongly punctured with 

 dusky or black. This species often liecomes of a blackish green 

 color, with the pale markings strongly contrasted. This is in fact 

 the only color I have seen in Mexican material. P. llguta ranges 

 from Mexico northward through the Rocky Mountains to Van- 

 couver Island and appai'ently still farther north to Alaska. The 

 Latin diagnosis of Kouchakevitch, a copy of which I give here, 

 agrees in every particular with our llgata, and J am sure there can 

 be no doubt of its identity. Some of the characteristic points men- 

 tioned in this description are the black antennse with a pale basal 

 joint; the pale calloused points on the scutellum and elytra, and 

 the olivaceous venter with j)iceous punctures and black stigmata. 

 The color, shape and markings agree exactly. Stal evidently did 

 not know of Kouchakevitch's paper, although it was published five 

 years before Part II of the Enumeratio.

The habitat given by Kouchakevitch for this species is Russian 

 America.
