is beset with uumerous, although uot deuse, long, erect hairs, forming trans- 

 verse rows on the dorsal side. 



Head horizontal, rather short, rounded, somewhat stout, inserted in the 

 prothorax. a transverse portion of the front, not much longer than the pro- 

 jecting parts of the mouth (including the epistoma), remaining uncoverd; 

 (lutcunpe inserted on the sides of the head, a little shorter than the breadth 

 of the labrum, 4-joiuted, basal joint very short, transverse, more than twice 

 broader than long, second joint subcylindrical, less than twice longer than 

 broad, third joint cylindrical, about the same length with the third, but 

 much narrower, obli(iuely truncated at the tip ; the fourth joint is repre- 

 sented by two minute, short articles, closely applied to each other and in- 

 serted in the truncature of the third joint; a black spot on each side of 

 the head, close behind the antenujv;, may foreshadow the appearance of 

 ocelli, which are not otherwise perceptible; front irregularly wrinkled, ep- 

 istoma short, transverse, its posterior suture very distinct, straight in the 

 middle, slightly oblique on both sides; labrum transverse, not longer and 

 a little narrower than the epistoma, horny, its anterior margin nearly 

 straight, slightly recurved in the middle, so as to form a distinctly elevated 

 edge; its surface has two minute impressed points, with a hair inserted on 

 each; niajidthhs horny, stout, slightly arciiated exteriorly and hollowed 

 out on the inside, with three blunt teeth at the tip; unless removed, they 

 arc concealed inside of the mouth and do not project beyond the labrum; 

 inaxillic : a short, obli(jue cardinal piece; a broad, coriaceous basal piece; 

 two lobes of the same consistency; the inner one narrow, short-lanceolate, 

 pointed at tip, with six or seven stout bristles on the inside; the other, 

 inserted between the first and the palpus, and separated from the basal 

 piece by a distinct sutu.re, is also coriaceous, rounded at tip. on the inner 

 side of which a palpiform, subcylindrical. stout joint, pointing inside, is 

 inserted; three stout bristles are placed immediately behind it; maxillary 

 palpi 4-joiuted, conical, joints of about e(|ual length, diminishing in 

 breadth; mrufnm large, flat, disclike, broader than long, rounded on the 

 sides, partly concealing the basis of the maxillae; palpigerous piece horny, 

 broad, with a bisinuated projection in the middle, between the palpi, 

 which are 2-jointed, short. 



Prothorax as long as it is broad, with numerous transverse wrinkles on 

 its anterior half, more smooth posteriorly; laterally it is bent on both sides 

 towards the pectus, so as to be convex above and concave below; its lateral 

 edges are sharp and project over the basis of the coxae; its anterior and 

 posterior margins above are straight; the lateral ones slightly rounded; 

 the angles are also rounded; its iinterior portion below is a triangular skin,
