Eyes placed just in front of the globose portion of the head, moderately large, rounded, not prominent, 



somewhat approximate above ; rostrum cylindrical, feebly arcuate, the antennae inserted at or just 

 beyond, the middle, with an ovate, abrupt club, the scrobes obliquely descending ; head transversely 

 depressed or foveate between the eyes ; prothorax suboval, not so long as broad, feebly constricted at the 

 sides in front ; scutellum small ; elytra with narrow punctured striae separated by broader interstices, 

 obtusely produced at the apex; anterior coxae separated by considerably less than their own width ; third 

 tarsal joint a little wider than the second, simple ; body narrow, oblong, almost glabrous. 



Type, T. rubicundus. 



The three small species included under this genus are nearly related to Stenomimus, 

 but they seem to be best separated from it. They are all of a ferruginous or rufo- 









_f 



testaceous colour, and have a cvlindrical rostrum, subapproximate, moderately large, 

 not very prominent eyes, narrowly punctate-striate elytra, and not very widely separated 

 anterior coxae. The ventral excavation of the male of T. rubicundus is peculiarly 

 shaped. Tytthomimus differs from Micromimus in the position of the eyes ; from 

 Caulophilus in the more slender limbs, &c. ; and from the various forms here referred 





\ 



to Rhyncolus in having the rostrum more distinctly separated from the head.

Oblong-ovate, narrow, rather convex, shining, ferruginous. Head smooth, shallowly transversely grooved and 

 narrowly foveate between the eyes, the latter large ; rostrum short and stout, feebly curved, sparsely, 

 very finely punctate, smooth along the median line. Prothorax a little broader than long, somewhat 

 oval, feebly constricted in front; closely, finely punctate, except along a rather narrow smooth space on 

 the middle of the disc. Scutellum conspicuous, smooth. Elytra moderately long, slightly wider than 

 the prothorax, subparallel to near the middle, the apices broadly produced, somewhat explanate, and 

 each bluntly and separately rounded at the tip ; punctate-striate, the interstices broader than the stria, 

 flat on the disc, convex at the apex, the ninth subcostate from about the basal third, each finely uniseriate- 

 punctate. Beneath sparsely punctate ; first ventral segment with a broad, deep excavation, in the centre 

 of which posteriorly is a transverse tuberculiform prominence, the fifth segment shallowly foveate; first 

 ventral suture strongly sinuate. Tibiae with a minute tooth at the inner apical angle, the anterior pair 



sinuate within.
