4. Corizus punctiventris Dallas. Brit. Mus. List. Heteropt., 

 vol. n, p. 523. 



Four specimens were collected at Wasatch, June 27. 



It is the Canadian species which spreads from the province of 

 Quebec across the region of the great lakes westward to the 

 Pacific States and from thence keeps on all the way south into 

 California and Northern Mexico. 



5. Corizus validus. New sp. 



This is more robust than any of the other species thus far discovered in 

 North America. It is of a pale greenish testaceous color, closely whitish 

 pubescent, remotely and minutely sprinkled with dark brown on the up 

 per surface, and less distinctly so on the under surface, the legs also 

 sprinkled, and each tarsal joint black at tip. Head a little longer than 

 wide, the vertex and front coarsely punctate and wrinkled, closely setose- 

 pubescent, back of head with a depressed longitudinal line, and the space 

 between the eye and ocellus raised like a tubercle; rostrum reaching upon 

 the posterior coxae, marked with a piceous line throughout its length ; 

 antennae stout, the basal joint a little dotted and streaked with black, the 

 tip of the second and third joints and apical two-thirds of the fourth joint 

 fuscous. Pronotum coarsely unevenly punctate with the intervals between 

 the punctures swollen, surface each side of disk, posteriorly, convexly 

 raised, humeral angles tubercular, bordered behind by a curved, pale 

 lamella, the posterior submargin forming a curved ridge which is marked 

 with brown spots, lateral margin bent down, the middle line unevenly 

 sulcate and occupied by a slender, pale carinate line, the anterior margin 

 depressed, bounded behind by a transverse ridge back of which the surface 

 is thrice indented, and each anterior angle set with a tubercle. The scu- 

 tellum subacute at tip, with the border upturned there, the base scooped 

 out and bordered each side by a short callous ridge, the middle line obso- 

 letely ridged, bounded each side by several lines of coarse punctures. 

 Wing-covers pale testaceous, translucent, the veins marked with remote 

 brown spots, the membrane milky-transparent, very obsoletely sprinkled 

 with brown. Pleural pieces pale greenish, coarsely punctate, the meso- 

 pleura especially coarsely so. Venter polished, punctate, minutely 

 sprinkled with brown, the tergum greenish, finely punctate, its disk 

 marked with black areas of variable size, the middle ones being separated 

 by slender cruciform lines of the ground color, the black marking either 

 carried back from the large spot of the penultimate segment as a fusiform 

 streak or divided into a series of geminate dots; connexivum with a small 

 brown slender spot at the incisure between the segments. Length to tip 

 of venter, 7^-8 millim; width of base of pronotum, 25-3 millim. 



Two specimens were secured near Great Salt Lake, June 13, 

 and another at Alta. Utah, June 30, from an elevation of 10,000 

 feet above tide. It belongs to the group of C. sidce Fab., but it 

 is much stouter and larger. Specimens in my own collection
