12 THE CANADIAN ENTOMOLOGIST, 



rounded on the sides." Casey (1892, 391) combined LeConte's 

 squamnlatHs with the corniculaitis as recognized by Dietz and his 

 description is a composite of the two. Dietz (1894, 164) described 

 a form as corniculatus, and then mentions" four varieties. These, 

 as lettered in his collection at Cambridge, appear to be a, a small 

 form ot his nehulosus; c. the same as described by him as cornicu- 

 latus; h, and </, the sciiiamulatiis of LeContc, of which Dictz's 

 columbiauus is a synonym. Until the type of Fahrieus is studied 

 by some American Coleopterist familiar with our species of Smi- 

 cronyx, the name corniculatus may, as well as any other, be ascribed 

 to the form so recognized by Dietz. 



.A study ot the type of S. Ian uiii)iosus Dietz in the Horn collec- 

 tion shows it to be a dwarf form (2 mm.) of corniculatus with the 

 "conspicuous long, hair-like setse" mentioned by Dietz visible 

 only when viewed in profile,, and then scarcely if an\- more obvious 

 than those of corniculatus when similarh- viewed. I consider it 

 scarcely worthy a varietal name. 



As mentioned above, Smicronyx squamulatus LeConte (1876, 

 173) was treated by Casey as a synonym of corniculatus, wiiich it 

 closely resembles, but differs in the maculate elytra, paler antennce 

 and distinct set"Ve of both thorax and elytra. Dietz (1894, 177) 

 mentions it as unknown to him, but "probably a variety of corni- 

 culatus.'' His types show, however, that he had described it 

 (1894, 162) as 5. columbianus, and also (p. 165) as varieties b and d 

 of corniculatus. 



Smicronyx quadrifer texana, var. nov. 



Differs from quadrifer Casey in having the scales of upper 

 surface mostly pale brown, the lateral stripes of thorax obsolete 

 on apical third, the median one reaching only to basal third; 

 elytral dark spot beginning at basal fourth instead of basal sixth, 

 with a white line running from its front margin to base along the 

 third intervals; each interval with a row of large, white, inclined 

 scale-like seta?, these absent on the median black spot.
