trilineatus by its smaller size, less elevated crest, fuliginous 

 elytra, and by the yellowish lateral vitta. On the metopidium 

 either side of the median carina is an obscure paler ray suggest- 

 ing the pale markings seen in trilineatus. 



3. Cyrtolobus (Xantholobus) inflatus n. sp. PI. 2, figs. 24, 25. 



A robust hairy species. Dorsum regularly arcuated with a distinct an- 

 terior sinus over the posthumeral sinus. Crest scarcely carinated, deeply 

 compressed at the middle, the small posterior cyst almost lost in the large 

 hemispherically inflated apex of the pronotum. Color pale yellowish, 

 punctured and varied with ferruginous and brown and with a broad angu- 

 lar belt of rufous brown across the middle of the pronotum, bounded before 

 and behind with whitish bands; anteriorly this rufous belt is advanced so as 

 to cover the anterior cyst of the crest, posteriorly it is eroded or slightly 

 emarginate. Metopidium with a suggestion of a brown ray on either side, 

 curved above the humeral angles. Elytra rufous brown at base with a pale 

 band over the whitish base of the tergum; subhyaline toward the apex. 

 Length 5 mm. 



Described from one female taken by me at Manitou, Colo- 

 rado, July 19th, 1900. 



4. Cyrtolobus (Xantholobus) nitidus n. sp. 



Small, finely punctured and polished. Pronotum very slightly carinate; 

 dorsal outline regularly and gently arcuated, a very little sinuated at the 

 anterior base of the crest, almost over the humeri; crest scarcely disting- 

 uished from the rounded surface of the pronotum, quite strongly compressed 

 at the middle. Color bright castaneous brown, paler anteriorly; metopidium 

 with a diffuse darker ray on either side above the eye; anterior oblique vitta 

 slender, almost obsolete above, nearly or quite confluent with the small 

 obscure median spot; posterior vitta broad, the small apex beyond it scarcely 

 darker, attaining the terminal areole of the corium. Head large, convex, 

 smooth, finely and closely punctured; anterior margin feebly arcuated; 

 clypeus viewed more from below moderately produced with a rounded apex. 

 Elytra subhyaline, castaneous at base and beyond the middle, with an 

 indistinct whitish band over the pale base of tergum. Beneath pale; legs 

 whitish, Length 5 mm. 



Described from three females: one from Lakehurst, N. J., 

 sent to me by Prof. J. B. Smith ; the second I took at Washing- 

 ton, D. C, in June 1905, and the third was received from Mr. 

 W. T. Davis who captured it on Staten Island, N. Y. Viewed 

 from above the pronotum in this species is considerably swollen 

 posteriorly. It is a neat and distinct little species.
