i:34 A. MATTHEWS. 



much produced and broadly yellow; elytra short, shorter hut not wider than the 

 head and thorax, widest at the middle, very convex, moderately asperate in re- 

 lapte, transverse, wavy rows; sides and apex much rounded, the latter pale; iib- 

 (lomen rather long, obtuse ; legs and antennse dusky yellow. 



Differs from T. ahrupta in its shining surface, remote sculpture, much 

 longer and paler hinder angles of the thorax, and longer and more slender 

 antennae — from others in its short, convex form, rounded sides and de- 

 pressed base of the thorax, and rounded elytra. 



Hah. — Central America, found by Mr. Champion on " Totonicapam," 

 Guatemala, at an altitude of 10,500 feet. 



T. minor Matthews n. sp.— L. c. .87 mm. — Oblong, oval, convex, rather shin- 

 ing, black, densely clothed with yellow hair ; head moderate ; eyes not prominent : 

 thorax rather long, longer and rather wider than the head, closely covered with 

 large tubercles in irregular rows, the interstices shining and faintly reticulate: 

 sides margined and moderately rounded, with an erect black seta on each side 

 before the middle, basal margin retiexed. and much sinuated, with the angles pale 

 and much produced; elytra fuscescent, sub-quadrate, not longer or wider than the 

 head and thorax, deeply and closely asperate in transverse rows; sides nearly 

 straight, with an erect black seta near the shoulder, and another beyond the mid- 

 dle on each side, apex broad, much rounded, pale, with the edge white ; abdomen 

 rather long, fuscous, with the apex bidentate : legs long and robust, bright yellow : 

 antenna long and slender, dark yellow. 



DiflPers from T. grandicollis in its much smaller .size, oblong form, and 

 deeper sculpture. 



Hah. — Central America, found by Mr. Champion in abundance near 

 San Greronimo, (xuatemala. 



T. grandicollis Mann (Trich. Illust. p. 135).— L.c. 1— .12 mm. — Rather 

 broad, very convex, brassy-black, thickly clothed with fulvous hairs; head large 

 and broad; thorax large, widest before the base, ornamented with moderate tu- 

 bercles irregularly placed, with the interstices reticulate; sides margined, and 

 very much rounded with an erect black seta on each side behind the middle, 

 hind angles acute, much produced ; elytra moderate, scanjely longer, but rather 

 narrower than the head and thorax, slightly rounded, furnished with an erect 

 black seta on each side near the shoulder, and also behind the middle, apex slightly 

 contracted and pale; antennae long, piceous, or black ; legs yellow. 



A single specimen of this species was found by Mr. Champion on 

 "Totonicapam," at an altitude of 10,500 feet. It seems strange that 

 this very common European insect should occur in such a locality, and at 

 so high an altitude, in Central America ; but, after the most careful ex- 

 amination, I can discover no point of form or sculpture in which this 

 specimen differs from the European examples of the female ; in this sex 

 the sides of the thorax are always less dilated than in the male. 



T. cognata MatthewsCist. Ent. 2, p. 176, 1877.— L.c. 1.12 mm.— Oval, rather 

 narrow, convex, black, clothed with very short pale hiiir ; head rather small ; I've:-
