at the sides, rufescent ; legs red ; antennae, tarsi, and palpi tes- 

 taceous ; club fuscous, opaque. 



Agrees almost exactly in most respects with Dr. Sharp's descrip- 

 tion of Adolopus helmsi. The punctuation of the head, the thorax, 

 and the discoidal portion of the elytra, though close and distinct, 

 cannot be termed coarse ; the serial punctures of the apical part of 

 the elytra almost form striae ; the sutural striae are impunctate. 

 Underside nearly black. 



When compared with A. altulus it will be seen that the raised 

 central portion of the metasternum is much broader, and it is more 

 distinctly punctured and pubescent. The abdominal carina is well 

 developed. 



The best distinguishing character will become apparent on an 

 examination of the posterior femora. These are not glabrous, being 

 in reality distantly punctured, and from each puncture there arises 

 a fine, short hair. The pubescent thighs, indeed, may be considered 

 sufficient to isolate the species. 



Length, If lines ; breadth, nearly line.

2345. T. crassipes, n - s > Shining, dark-red, palpi and tarsi 

 yellow ; sparsely clothed with very short yellowish hairs. 



Head subovate, not prolonged anteriorly, about as large as the 

 thorax, without distinct interocular foveae or punctuation; antennal 

 tubercles contiguous, small, not prominent. Eyes distinctly facetted, 

 rather flat. Thorax rather longer than broad, convex, oviform, 

 without foveae or impressions, obsoletely and remotely punctured. 

 Elytra about twice the width of the thorax behind, but much nar- 

 rowed towards the base, apices widely incurved and depressed; 

 sutural striae moderate, more deeply impressed near the base, intra- 

 humeral impressions narrow, their surface more or less distantly 

 punctate. Hind-body rather flat and broad, very Pselaphiis-like ; 

 the basal segment medially depressed in front, about as long as the 

 elytra, the following segments short and deflexed. Legs unusually 

 thick, tibiae slightly arched externally ; tarsi short and stout, claws 

 small. 



Antennce short and stout ; basal joint cylindric and thick ; 

 joints 2-8 differ but little, but gradually decrease ; ninth and tenth 

 transverse, the ninth nearly double the breadth of the eighth ; the 

 eleventh large, oblong-oval. 



This has the appearance of a Pselaphus. It may be easily 

 identified by the oviform head, robust legs, and short antennal 

 joints. The maxillary palpi, though shorter than those of T. mu- 

 tandus, are very similar in structure. The metasternum is very 

 convex ; there is a depression between the hind coxae ; the pro-
