NOTE ON I. POLIOS. 



In the lower part of the plate are represented paratypes No. 23 

 (S under surface), No. 24 ( (^ upper surface), No. 25 ($ under surface), 

 and No. 26(9 upper surface), of /. polios, described in the Canadian 

 Entomologist for June, p. 202. It may be pertinent to state that the 

 food-plant oi polios has been discovered, eggs secured, and the larvae now 

 being raised have already passed the first moult. The specific validity of 

 the form is no longer open to question. 



NEW COLEOPTERA FROM THE SOUTHWEST.— III. 



BY H. C. FALL, PASADENA, CALIF. 



Pteroloma caraboides, n. sp.— Blackish-brown, moderately shining, 

 legs and antennae somewhat paler. Antennae as usual. Head sparsely 

 finely punctate. Prothorax 2/5 ( ^ ) to 1/2 (?) wider than long, widest 

 at or slightly in advance of the middle, base a little wider than the apex, 

 sides moderately rounded, oblique and just perceptibly sinuate posteriorly, 

 hind angles sharply defined, but slightly obtuse; disk evenly, rather feebly, 

 convex, median line not at all impressed, side margin acute and slightly 

 reflexed, a feeble impression within the hind angles; surface finely, sparsely 

 punctate, the punctures somewhat unequal in size, and becoming more 

 numerous near the basal and lateral margins. Elytra elongate oval, a 

 little wider at base than the prothorax, more than three times as long as 

 the latter, and more than one-half longer than wide ; sides arcuate, feebly 

 sinuate before the apex, which is narrowly rounded ; striae strongly 

 impressed, distinctly but not coarsely punctate ; intervals very finely and 

 sparsely punctulate, the alternate ones with a series of distinct and feeble 

 larger punctures. Body beneath distinctly alutaceous, but shining and 

 very finely, sparsely punctate. Epipleura minutely and sparsely punctate. 

 Length, 6;^-7 mm. 



Wenatchee, Washington, collected by Prof. H. F. Wickham; Mt. San 

 Antonio, So. California, a single example taken at an altitude of about 

 9,000 ft. by Mr. C. A. Richmond. 



The male has the front tarsi quite strongly dilated, the first two joints 

 of middle tarsi moderately so. 



This species has the general form q{ Forstroemei, but differs — judging 

 from the description — in the more finely punctate thorax, with median line 

 unimpressed, the much less distinct serial punctures of the alternate elytral
