198 Major T. Broun on some 



with obtuse angles ; the fovese rather shallow, not distinctly 

 extending forwards to the rather flat forehead ; auteunal 

 tubercles" distant and small, Ei/es moderately large^ not 

 verv convex, situated at the middle. Thorax of about equal 

 leu'ffth and breadth, rounded and widest just before the 

 middle, rather more narrowed in front than behind ; it is 

 quite distinctly but irregularly punctured, most closely near 

 the base ; lateral foveae subrotundate and deep, without any 

 definite anterior prolongation, and not distinctly united to 

 the semicircular basal fossa, discal furrow moderately broad 

 and deep and almost reaching the apex. Elytra subquadrate, 

 with somewhat rounded shoulders, a little depressed at the 

 base and apex, without definite puuctation; sutnral striae 

 broad, deep, and foveiforni at the base, but duplicated for 

 most part of their length, the outer border of each carinate 

 at the base, more feebly so behind ; intra-humeral im, 

 pressions also deep and broad at the base, but becoming 

 obsolete towards the middle. Hind body rather shorter than 

 the elvtra. much narrowed and deflexed near the extremity. 

 the basal three segments subequal. 



Legs rather long, simple. 



Antenna fully the length of the head and thorax ; basal 

 ioint cvlindrical and nearly twice as long as broad, second 

 oviform, evidently longer than broad, the next small and 

 subovate, joints 4-8 small and mouiliform, the eighth 

 shortest, fifth and seventh slightly larger than adjacent ones, 

 ninth moderate, distinctly larger than the preceding one, 

 but not as broad as the trans\erse tenth, the terminal one 

 nearly the length of the preceding three combined, conical 

 and acuminate. 



Underside finely pubescent, pale chestnut-red. Prostei'uuiu 

 carinate along the middle. Metasicrnum convex and 

 moderately elongate. Basal veiftral segment covered by the 

 femora, second obtusely elevated across the middle for nearly 

 half of its whole breadth and minutely ciliate behind, third 

 curvedlv depressed across the middle of the base and about 

 as long as the following two singly, sixth large, obtusely 

 triangular, the operculum distinct, oviform, and extending 

 from the apex nearly to the base. 



After studying the descriptions of the five species (3198- 

 3202) referred to Trichonyx by Herr Reitter, I feel pretty 

 sure that the peculiar duplication of the sutnral striae and 

 the rather plane head are sufficiently good distinguishing 

 characters. None described by me are exactly similar.
