168 THE CANADIAN ENTOMOLOGIST. 



altitude of about 4.500 feet. This locality is in Southern Utah, about 

 twenty-two miles from St. George, on the road between that place and 

 Modena. The species is abundantly different from G. obliteratus by its 

 smaller size, different colour and sculpture, shape of the head and struc- 

 ture of the antennae. From G. planicosta it differs not only by the above 

 characters, but also in lacking raised elytral costa;. G. cuneatus is 

 described as being larger (.75 inch. =18 mm.), of different colour and 

 with truncate epistoma. The food habit of this species is noteworthy, G. 

 obliteratus being found on several species of desert shrubs, while G. 

 planicosta frequents especially the bushes of Larrcea Mexicana. Although 

 G. obliteratus was rather abundant at St. George throughout July, I did 

 not see it in the neighbourhood of the ranch at all. 



Hydnocera, Newman. 



H. Kjtausii, n. sp. — Form moderately elongate, not notably convex. 

 Testaceous; legs and antennae yellowish, eyes, metasternum (excepting 

 the side pieces), abdomen, scutellum and elytral bands black, the tibiae 

 near the base and the middle of the hind femora more or less infuscate. 

 Surface with rather long, sparse, whitish pubescence. Head (with the 

 prominent eyes) about one-fourth wider than the prothorax, front intri- 

 cately rugose, antennse shorter than the head, first and second joints large 

 and stout, third a little longer than the fourth, club regularly ellipsoidal 

 pointed at the tip. Prothorax rugose, about ojie-fourth broader than long, 

 widest in front of the middle, where the sides are gibbous, thence nearly 

 parallel to the base, which is strongly beaded. Elytra about one-fourth 

 wider than the prothorax and nearly twice as long as broad, subparallel, 

 slightly narrower and dehiscent behind, humeri prominent, surface 

 alutaceous, coarsely, closely and deeply but regularly punctured, the 

 punctures becoming so large near the apex as to give rise to a reticulate 

 appearance. In colour they are reddish, each with the posterior two-fifths 

 and a submedian band black, the interspace bearing a transverse patch of 

 more conspicuous silvery hairs. Margins coarsely serrate posteriorly. 

 Beneath, the thoracic sidepieces are rugose. Legs with long, sparse, 

 bristly hairs. Length, 3.25 mm., .13 inch. 



The type was given me by Mr. Warren Knaus, who took it at Mc- 

 Pherson, Kansas, September 30. It is quite different from any of the 

 described North American species, and in view of the successful attention 

 bestowed on the fauna of Kansas by Mr. Knaus, I have dedicated this 

 pretty insect to him.
