Antennal characters of («) Notaris puncticollis ; (/>) A', wyoviingensis. 



Notaris wyomingensis, new species. 



Form similar to puniticollu Lee, but proportionately more slender; black, anten- 

 nae, tarsi and tibiae rufo-piceous. Rostrum somewhat finely and sparsely punctate, 

 not carinate, surface shining. Antennae of 9 inserted near middle of rostrum, of 

 $ two-fifths from apex. Last funicular joint subtriangular, considerably larger than 

 the preceding, as long as wide ; club wide, not as long as preceding four joints. 

 Thorax a little wider than long ; sides rather strongly arcuate ; surface coarsely 

 densely, subrugosely punctate, sparsely covered with scale-like yellowish setae, di- 

 rected transversely, forming a dorsolateral fascia each side and leaving a median 

 smooth line extending from apex about four-fifths to base. Elytra ( 9 ) one-third 

 or less wider than thorax ; humeri rounded ; striae shallow, intervals densely punc- 

 tate, sparcely pubescent, consisting of very short scale-like setae, third interval fiat 

 or feebly elevated, bearing a small tuft of prostrate whitish hairs behind the middle. 

 Lower surface moderately coarsely, densely and nearly uniformly punctate, the punc- 

 tures growing a little finer but not denser apically. The apex of the fifth abdominal 

 segment somewhat strongly reflexed. Posterior tibiae without short terminal spurs. 



Length. — 6.5-7.5 mm.; width: 2.2-2.8 mm. 



Habitat. — Cheyenne and Laramie, Wyo. (H. Soltau) ; "Wyo."; 

 Colorado. 



Type. — No. 9,757, U. S. National Museum. 



The natural food plants of the species of Notaris occurring in 

 America do not appear to have been positively ascertained, although 

 Mr. F. M. Webster has surmised that puncticollis "may breed in the 

 common Typha latifolia or cat-tail." He observed this species attack- 

 ing cabbage on land that had been drained (Insect Life, vol. vii, 

 1894, p. 206). 



Allied European forms such as Erirhinus festuar Hbst., have 

 been observed breeding in the stems of Scirpus, and the beetles have 

 been found on Cyperaceae, especially on Carex. The genus favors 

 aquatic vegetation and the beetles are usually found in moist situations.
