THE CANADIAN ENTOMOLOGIST. 67 



NEW COLEOPIERA FROM THE WESTERN UNITED STATES. 



RV H. F. WICKHAM, IOWA CITY, IOWA. 



All of the species described in the following pages belong to genera 



which are of small extent or have been recently monographed, and it is 



hoped that no confusion will result from their publication. The types are 



in my own collection, and, unless otherwise credited, were captured by 



myself. 



Physorhinus, Esch. 



Hitherto the only species of this genus known from the United States 

 was P./uscuIus, Champ. (Anchasi us frontalis, Horn), and the curious 

 pale head, which Dr. Horn thought might be accidental, is, according to 

 Mr. Champion, characteristic of the genus, which is well represented in 

 Central America. I have in my collection a form which seems to be new. 



P. yucca, n. sp. — Elongate, subfusiform, convex, shining, clothed with 

 rather dense yellowish pubescence; castaneous, legs rather lighter. Head 

 yellow, clypeal margin blackish, the surface deeply but somewhat finely 

 punctate ; antennas passing the hind angles of the thorax, second joint 

 extremely small, third barely longer, together about equal to the fourth. 

 Prothorax a little wider than long, broadest behind the middle, rapidly 

 narrowing to apex, sides nearly parallel behind, hind angles just percepti- 

 bly divergent, acute, bicarinate, the inner carina straight, oblique, outer one 

 very slightly curved and quite near the margin ; surface deeply and dense- 

 ly but not very coarsely punctured, the punctuation of the neigiibourhood 

 of the anterior angles being the coarsest. Elytra at base not as wide as 

 the thorax, becoming rapidly narrower from a point much in advance of 

 the middle, sides slightly rounding, apices distinctly finely serrulate, tips 

 conjointly rounded, all the stride distinct, but fine, with small distant punc- 

 tures at bottom, interstrial spaces finely, irregularly and rather closely 

 punctate. Beneath somewhat finely and closely punctured. Dilated por- 

 tion of posterior coxal plates rounded at tip. Length 1 1 mm. 



Taken near Brownsville, Texas, by C. H. T. Townsend and myself, 

 in heads of Yucca during July. Differs from P. ftiscultis by the closely 

 punctured head. It is quite closely allied to the Mexican P. frontalis, 

 Cand. The Central American species are said by Champion to occur 

 mostly in forest clearings, and are collected by beating branches of trees. 



Chrysobothris, Esch. 



C. "Piiita, n. sp. — Form oblong, subdepressed, bronzed, shining, 

 head bright reddish cupreous, front green ; pronolum reddish cupreous,
