strongly transverse and perfoliate. Prothorax transversely oval, tliree-fourtlis 

 wider than long, the sides rounded and convergent anteriorly, becoming par- 

 allel and nearly straight in basal half ; base slightly bnt distinctly wider than 

 the apex, both strongly arcuate ; basal angles obtuse and blunt ; disk strongly 

 convex, the median line feebly impressed and with a feeble transverse impres- 

 sion before the base. Elytra transverse, nearly one-half wider and two-fifths 

 longer than the prothorax ; sides slightly divergent and arcuate from the 

 humeri, the latter narrowly rounded, rather broadly exposed at base ; disk 

 convex, very broadly, feebly impressed near the scutellum. Abdomen short, 

 when moderately contracted not as long as the anterior parts, as wide as the 

 elytra ; border rather strong and thick. Length 1.35 mm.; width 0.55 mm. 



Iowa (Cedar Rapids). Dr. E. Brendel. 



The large series before me exhibits scarcely any variation, ev^en 

 in size. A specimen which I took at Galveston, Texas, differs but 

 very slightly and is probably conspecific. 



T. parvicollis n. sp. — Oblong, convex, pale rufo-testaceous throughout, 

 with the exception of a small piceous cloud on the fourth tergite ; integuments 

 strongly shining, the head and pronotum subimpunctate, the elytra very 

 minutely, rather closely but scarcely distinguishably, the abdomen minutely, 

 rather closely and subasperately ; vestiture long, erect, ashy and bristling 

 from every part of the body. Head wider than long, strongly impressed in 

 the centre, fully three-fourths as wide as the prothorax, the eyes rather large, 

 at scarcely more than their own length from the base ; tempora feebly con- 

 vergent and arcuate behind them to the very broad neck ; antennae longer, 

 unusually slender, extending to the middle of the elytra, the first joint longer 

 than the second, the latter scarcely longer but thicker than the third, four to 

 six moniliform, subglobular, nearly similar, seven to ten very slightly increas- 

 ing in width, the tenth slightly transverse, eleventh small, ovoidal, obtusely 

 acuminate, only one-half longer than the tenth. Prothorax small, transverse, 

 three-fifths wider than long, the sides strongly convergent, evenly and moder- 

 ately arcuate from base to apex ; base much broader and more strongly arcuate 

 than the apex ; basal angles obtuse and blunt ; disk strongly convex, feebly 

 impressed along the median line toward base only. Elytra strongly transverse, 

 three-fifths wider and two-fifths longer than the prothorax ; sides but feebly 

 divergent and slightly arcuate from the humeri, which are right, scarcely 

 rounded and broadly, transversely exposed at base. Abdomen scarcely as long 

 as the anterior parts, in the middle as wide as the elytra, but at base distinctly 

 narrower ; sides parallel and arcuate ; border thick ; posterior margins of 

 tergites three and four broadly, feebly sinuate in circular arc throughout the 

 width ; fifth distinctly longer than the fourth, transverse at apex. Posterior 

 tarsi two-thirds as long as the tibiae, the first four joints equal, the fifth as long 

 as the preceding two. Length 1.7 mm. ; width 0.65 mm.

This species is somewhat aberrant in its longer, more slender and 

 less incrassate antennae, and longer fifth ventral segment. It is
