which enabled it to reach the Sugar Maple district of New 

 York is the common Huckleberry. 



Upon careful comparison I fail to find the slightest differ 

 ence between specimens breeding in Huckleberry and others 

 sent by Dr. Merriam, but I take this opportunity to describe 

 another species of Corthylus which occurs within the political 

 boundaries of the United States, but which evidently belongs 

 to the colony of West Indian species in southern Florida. 



Corthylus spinifer n. sp. Form oblong, robust ; color piceous or 

 reddish-brown ; legs and antennae pale-reddish. Byes large, transverse, 

 deeply emarginate in front, antennae inserted in front of the emargina- 

 tion. Thorax and elytra glabrous excepting a few hairs on the front 

 margin of the former. Thorax slightly longer at middle than wide, an 

 teriorly much rounded ; sides parallel when viewed from above ; basal 

 marginal line well marked and forming an obtuse angle with the lateral 

 line, which nearly reaches the front margin ; asperities smaller than in 

 C. punctatissimus and indistinctly arranged in concentric rows ; poste 

 rior half of thorax smooth and tolerably shining. Scutellum semicir 

 cular, smooth. Elytra barely as wide as and but little longer than the 

 thorax, cylindrical, broadly rounded at tip, surface shining, finely and 

 rather sparsely punctulate, the punctures irregular except on the disc, 

 where they are distinctly seriate ; declivity nearly vertical, slightly 

 retuse, irregularly punctulate, on each side with a longitudinal series of 

 three small cusps, and margined on each side at its apical third by a 

 rather well-defined smooth ridge ; suture elevated on the declivity ; su- 

 tural space not perceptibly excavated and densely punctured. Front 

 tibiae nearly linear, straight, outer edge finely serrulate and with two 

 larger teeth near the tip, terminal uncus rather blunt and curving out 

 wardly. Abdomen rather densely punctured and hairy. Length, 2 mm. 



Male : Surface of head flattened and depressed, the depression rather 

 deep in front, gradually shallowing posteriorly and covered with rather 

 dense yellowish, but not very long, pubescence, sculpture concealed by 

 the pubescence on the anterior part of the depression, posterior portion 

 moderately shining and finely punctulate. Antennal scape greatly 

 dilated toward the tip, triangular, apical edge straight ; funicular joint 

 very small, transverse ; club very large, nearly circular in outline, 

 densely punctulate and hairy and with three distinct sutures, of which 

 the basal one is nearly straight but distinctly angulated near the anterior 

 end, the two outer sutures decidedly, almost semicircularly, arched ; 

 from the base of the inner surface of the club arises a slender spine 

 which, following at first the curvature of the posterior edge of the club, 

 projects above the club and curves inwardly, the projecting portion of 

 the spine being as long as or longer than the whole antenna. If the 

 antennae are applied to the sides of the head the tips of the two spines 

 overlap each other. 



Female : Unknown.
