1828. H. bifoveatus, us. Shilling, glabrous, pitchy-black, 

 antemiEe yellow, tarsi and palpi rufo-fulvous, legs red. 



Very much like H. minor, the body more oval, labrum distinctly 

 longer ; thorax rather less transverse, with less rufescent sides, and 

 with two well-marked round foveas on the middle ; elytra rufescent 

 behind, apical margins slightly explanate ; intermediate tihi(e rather 

 more scabrous ; basal joint of hind tarsi very short, scarcely pro- 

 jecting beyond the coarse cilise at the extremity of the tibise, the 

 other joints more evidently articulated. 



Length, 2i- ; breadth, nearly If lines. 



Clevedon. One example, found by Mr. G. Munro. 



Tormissus. 



Nov. gen. 



The structural characters of Hydrostygiius are, to a great extent, 

 exhibited in Tormissus, which, however, diiifers in some important 

 points. The basal joint of the antenna is more elongate, being quite 

 as long as the five following joints taken together. The basal joint 

 of the hind tarsus is quite one-half the length of the second. The 

 posterior femora are very minutely and densely punctured, but are 

 without pubescence. The middle of the mctasternum is only feebly 

 sculptured, and its iutercoxal process is narrower. The mesosternal 

 portion of ih.Q yectoral 'proniinence is conspicuous and quite erect. 



From Tormus it is distinguished by the emarginate labrum and 

 epistome, by the structure of the tarsi, and by the evidently sepa- 

 rated middle legs, kc. 



1829. T. marginatus, '^-s. Oval, convex, glabrous, shining, 

 nigro-piceous, tarsi dark-red, labrum reddish, antennae and palpi 

 fulvescent. 



Body closely and moderately punctured. Eijcs smooth. Thorax 

 transverse, curvedly narrowed anteriorly, hind angles not quite 

 rectangular, but not widely rounded, the lateral margins thicker 

 behind than in front. Elytra with, on each, ten series of well- 

 marked large punctures, the sutural strite quite distinct behind, the 

 punctuation not so evident and regular on the hind slope as it is in 

 front. 



The labrum not as large as in Hydrostygnus, its frontal incurva- 

 ture, and that of the epistome too, not so deep. The legs similar. 

 Tarsi not so densely pubescent, moderately laxly articulated. 

 Anterior coxce larger, densely and finely pubescent, the femora 

 similarly clothed, as, indeed, is most of the under-surface of the 

 body. Antemioi with the club and intermediate joints like those of 

 Hydrostygnus frontalis. The body rather more oval. 



Length, 3-| ; breadth, 2|- lines. 



Mokohinou. One damaged specimen, found by Mr. Sandager. 



1830. T. magnulus, n.s. Convex, oval, slightly nitid ; black, 

 tarsi red, legs darker, antennas and palpi pale-ferruginous. 



Head densely and finely punctured; eyes not prominent, with
