II. Thorax without crescent-sliaped furrow at base, its disc, 

 as a rule, furnished with two longitudinal furrows, which 

 are sometimes obsolete, and occasionally wanting. 

 i. Third joint of antennas a little shorter than second; 

 joints 5-7 oblong ; length 24-3 mm. 



1. Elytra more strongly punctured ; sides of thorax 



evidently rugose and duller; average size larger , T. bilineatds, Steph. 



{nee Er.). 



2. Elytra more finely punctured ; sides of thorax not 



or very slightly rugose and not duller; average 



size smaller T. eivularis, Mots, 



ii. Third joint of antennas somewhat variable, but usually 

 about half as long as second ; joints 5-7 as long as 

 broad ; head much narrower than thorax which is not 

 visibly foveolate on disc ; legs clear testaceous ; length 



2-2^ mm T. FCLiaiNOSUS, Orav. 



iii. Third joint of anteunse much shorter than second (the 

 latter being about three times longer than the former) ; 

 joints 5-7 always transverse. 

 1, AntennsB black, with at most the first joint pitchy 

 brown or pitchy red. 



A. Legs, except knees, tarsi, and trochanters, black; 



elyti-a rather strongly and thickly punctured; 



length 1^ mm T. foveolatus, Sahlh. 



B. Legs pitchy or pitchy testaceous, with femora 



darker ; elytra finely punctured. 



a. Head and thorax plainly punctured, the latter 



with dorsal furrows distinctly traceable ; length 



lf-2 mm T. COETICINUS, Grav. 



b. Head and thorax very finely shagreened, the 



latter without dorsal furrows, but indistinctly 



foveolate at base. L. 1^ mm T. halophilus, Kies. 



2 Antennas dark with base more or less broadly reddish 

 or reddish-testaceous. 



A. Elytra about as long as, or slightly longer than, 



thorax, the latter with two obsolete dorsal fur- 

 rows, legs red or pitchy red ; length 2 mm. . . T. elongatulus, Er. 



B. Elytra much longer than thorax ; legs clear tes- 



taceous; length not exceeding 1| mm. 



a. Thorax distinctly transverse; dorsal furrows 



rather distinct, divided, taking the form of 



four shallow depressions T. pusillus, Grav. 



b. Thorax not transverse, as long as broad ; dorsal 



furrows as in the preceding, but very indistinct. T. tknellus, Ur. 



3. Antennae entirely testaceous ; tliorax not transverse; 



form extremely narrow and linear T. subtilis, Er. 



The sexual characters of the genus do not require particular mention ; 

 in T. arcuatus the seventh ventral segment of hind body is very narrowly 

 and angularly emarginate in middle of apical margin ; in the other 

 species the same segment is feebly bisinuate or almost truncate, the 

 central portion being more or less, but always slightly, advanced. 



T. arcuatus, Steph. {scroUculatus, Er., Carpalimus arcuatns, 

 Steph.). Kather broad and depressed, black, somewhat shining, clothed
