CYLlXUltOltHIXIDAE. J 27 



which is curved inwardly behind; the vertical sides have similar 

 sculpture. > 



Tliis species is smalk'r than T. aterrima, 3288, and may be at once 

 distinguished by the entire absence of granulation on the thorax and 

 elytra. 



T. lat/'rosfris, 2911, has more parallel-sided and differently sculptured 

 elytra; the joints of tlie fi'ont tarsi are evidently longer and sub- 

 triangular, whereas the basal two in T. laer/rosfafa are shurt and 

 broad, and the antenna! club is more slender and a good deal narrowed 

 towaids its base; 2911, moreover, has a differently sculptured thorax 

 and a small yet distinct scutellum, but in the present species the scutelhim 

 is very narrow and hardly visible.

Subovate, moderately convex, a little nitid; black, antennae and 

 tarsi rufo-piceous; sparingly clothed with greyisli, rather fine, decumbent 

 squamae, which, on the elytra, are concentrated so as to form 4 longi- 

 tudinal streaks on each. 



Rostrum rather elongate, subparallel, and not dilated anteriorly, of 

 about the same length as the thorax; distinctly punctate, with an 

 elongate interantennal impression; there is a similar mark l)etween, 

 but in front of, the flat, strongly transverse eyes. Thorax unusually 

 elongate for this genus, being quite as long as it is broad, only very 

 slightly wider at or just before the middle than behind, where its sides 

 are nearly straight; in front it is somewhat abruptly contracted; along 

 tlie middle there is a shallow impression which is most distinct at the 

 base and almost divided lengthways near the centre; the adjacent space 

 is finely and distantly punctured, but, outside of it, the sculpture con- 

 sists of large, very iriegularly formed, shallow impressions; these are 

 nearly covered with scales; neai- each side tlie punctation is coarsei- than 

 that near the middle. Elytra oval, fully double the length of the thorax, 

 and rather broader than it is at the base; each elytron, including 

 the convex suture and lateral margin, is quadricostate : the 3rd costa 

 does not reach the extremity; each of the flattened intervals has 2 series 

 of moderately coarse punctures; these are placed close to the ridges, 

 and are more or less intei-mingled witli small gi-nnules, near the suture 

 especially. 



Femora medially dilated. Tibiae slightly flexuous, mucronate or 

 spurred at the inner extremity, and with a second more slender spur 

 a little further from the apex. Tarsi, excepting the 3rd joint, almost 

 glabrous underneath, the basal two joints, however, at the apices, have 

 concentrated patches of rigid setae, causing them in some aspects to 

 appear unsymmetrical ; in old abraded specimens tliese patches are 

 absent. 



Scape inserted near the apex, slightly Hexuous, and extending back- 

 wards to the eye; basal two joints of the funiculus nearly equal and 

 about twice as long as broad, 3-6 short l)ut not moniliform, 7th obconical 

 and evidently larger tlian the Gtli ; club short, ovate, obliquelv narrowed 

 outwardly. 



This species is remarkable on account of its elongated thorax.
