THE CANADIAN ENTOMOLOGIST 385 



NEW COLEOPTERA. VII. 



BY H. C. FALL, PASADENA, CAL. , 



In view of the possible appearance in the not distant future 

 of a synopsis of the North American species of Conotrachelus, it 

 is thought best to present at this time descriptions of two new 

 species, which have been drawn up for some time. With these 

 are submitted descriptions of what appear, with presertt hght, 

 to be five new species of Ceutorhynchus. - It is rather remarkable 

 that four of the five w^ere taken at the same place — Aweme, Mani- 

 toba- — and all in the same month, by Mr. Norman Criddle, who 

 has sent them to me for determination. Types of all the above 

 are in my collection. 



Conotrachelus Sch. 



Conotrachelus biscaynensis, n. sp. 



Form approaching that of anaglypticus, but with the pro- 

 thorax somewhat wider and the elytra a little less robust. Colour 

 piceous, the beak and tibia? dark rufous; vestiture consisting of 

 rather narrow to linear appressed scales, mostly brownish fulvous 

 in colour and irregularly dispersed, with a few, usually broader, 

 creamy white scales aggregated in v^ery small spots, mostly along 

 the elytral ccsta?. Head coarsely punctate, with a small, incon- 

 spicuous frontal fovea; beak about two-fifths the length of the 

 body, polished and ^■ery sparsely, finely punctate apically, lightly 

 sulcate at sides posteriorly; antennse inserted at apical third. 

 Prothorax a little wider than long, sides parallel and straight in 

 about basal half, thence a little oblique nearly to the apical con- 

 striction; surface coarsely, densely cribrate punctate, median line 

 imperfectly and incompletely carinate. Elytra one-half wider at 

 base than the thorax, sides feebly sinuate for a short distance at 

 base, becoming widest at about -basal third, thence arcuately 

 narrowing to apex; strial punctures rather coarse, intervals 3, 5, 

 7, 9 acutely carinate throughout. Mescsternum not protuberant; 

 metasternum grossly punctate; first ventral similarly, coarsely but 

 still more sparsely so, following segments broadly smooth and 

 polished at middle, punctate only at sides, last segment unmodi- 

 fied. Femora obscurely annulate and unidentate. 



Length 4.1 mm.; width 2.2 mm. 



November, 1917
