104 NORTH AMERICAN 



not prominent, more visible from beneath than above ; labrum rather large, 

 concealed from above, strongly inllexed, wider than long, truncate at tip 

 where it bears four or five short setae ; antennae about as long as the width 

 of head, rather slender, club moderate, basal joint longer and more robust 

 than the second. Prothorax large, just visibly wider at apex than the head, 

 four-fifths wider posteriorly, widest slightly before the base where it is about 

 twice as wide as long ; anterior margin transverse, posterior broadly emargi- 

 nate, transverse and straight in the middle of the emargination, sinuate 

 toward the posterior angles which are rather strongly produced and very 

 acute; disk very convex, polished, very finely feebly and transversely stri- 

 gose. itnpunctate except the rather conspicuous pores for the reception of the 

 bulbous roots of the hairs. Scutellum large, triangular, wider than Ion";, 

 asperate. Elytra widest in the middle where they are distiiu-tly iKirrower 

 than the pronotum ; sides parallel and just visi))ly arcuate; conjointly 

 abiuptly truncate behind, truncation broadly arcuate ; inner apical angles 

 very slightly rounded ; disk but very slightly longer than wide, about two- 

 fifths longer than the pronotum, moderately convex, rather coarsely some- 

 what strongly and distantly asperate, shining. Legs rather short ; femora 

 robust, compressed ; tarsi extremely slender ; anterior coxae large, nearly 

 globose ; anterior tibia having at the tip several fine slender interior spines. 

 Abdomen very short, basal joints concealed under large transverse lamellar 

 extensions of the posterior cttxae ; pubescence long and fine. Length 0.8 mm.

I found this spec-imen running amongst the roots of" grass in a dense 

 turf. It appears to be distinct troni ifhibricuUls, the only described 

 species with which it can be compared, as in that species the elytra 

 are widest behind the middle and are shorter than the head and pro- 

 thorax together, while in the present form the elytra are widest if 

 anything before the middle and are slightly longer than the head and 

 prothorax together; the antennae are fiavate in f/hibn'col/is wliicl^ is 

 not the case in rndicola. The sides of the prothorax are much less 

 arcuate than in the figure of glahriruIUs given by Mr. iNIatlhews, and 

 the sides of the elytra are much more convergent posteriorly through 

 the apical half. 



The abdomen in the type is very much drawn up so that the tip 

 scarcely attains the elytral apex, and the light shining through the 

 lateral portions of the latter is of a |)ale flavate color ; I do not think, 

 however, that the tip is actually paler. The same translucency is 

 seen in the thin posterior angles of the pronotum, whi(;h are conse- 

 (pu-ntly paler and fulvous. 



T. fllllgiiillH n. sp. — Form robust, oldong ; sides parallel ; rather con- 

 vex. Color above ])iceous-black, elytra becoming rufo-piivous toward the 

 tips which are margined with fulvous ; under surface of the alidomen, legs, 

 coxae, oral organs, and basal joints of the antennae rather dark piceo-testa-
