2. Tytthomimus rufotestaceus, sp. n. 



Oblong-ovate, narrow, moderately shining, faintly alutaceous, ferruginous or rufo-testaceous. Head almost 

 smooth, transversely depressed and sometimes foveate between the eyes, the latter moderately large and 

 separated by less than their own width ; rostrum short, stout, feebly curved, parallel- sided in its outer 

 half, sparsely, very finely punctate, the antennae inserted at the middle. Prothorax not quite so long as 

 broad, suboval, the subapical constriction indistinct, obliterated above; closely, finely punctate, with an 

 abbreviated smooth median line at the base. Scutellum almost smooth, conspicuous. Elytra moderately 

 long, a little wider than the prothorax, subparallel in their basal balf, broadly produced at the apex, the 

 apices somewhat explanate and bluntly, separately rounded; narrowly punctate-striate, the interstices 

 broader than the strise, convex at the apex, finely uniseriate-punctate. Beneath sparsely, finely punctate ; 

 first ventral segment broadly depressed down the middle anteriorly in the $ . Tibiae feebly mucronate 

 at the inner apical angle, the anterior pair sinuate within.

the subapical constriction almost wanting ; the ventral depression of the male shallow

the longer and more slender legs, &c, separate T. rufotestaceus from Caulophilus 





sericatus.

3. Tytthomimus lineatocollis, sp. n. 







Moderately elongate, narrow, somewhat depressed, obscure ferruginous, finely alutaceous, feebly shining. 

 Head closely, finely punctate on the vertex, foveate and slightly depressed between the eyes, the latter 

 large and separated by a little more than half the width of the rostrum; rostrum cylindrical, rather 

 slender, about as long as the posterior portion of the prothorax, sparsely, finely punctate, the antennae 

 inserted at the middle. Prothorax nearly as long as broad, somewhat oval, abruptly constricted in front ; 

 closely, finely punctate, except along the smooth median line, which extends from the base to the sub- 

 apical constriction. Scutellum small. Elytra moderately long, slightly wider than the prothorax, 

 subparallel to beyond the middle, obtusely produced and subexplanate at the apex ; narrowly punctate- 

 striate, the interstices much broader than the striae, flat, transversely rugulose, and closely, conspicuously 

 uniseriate-punctate. Beneath closely, finely punctate ; first ventral segment narrow!) 7 depressed down

One specimen. More 



elongate 



and more depressed than the two other species 









referred to this genus, the head punctate on the vertex, the rostrum longer and not so 

 stout, the prothorax with an almost complete impunctate median line, the elytral 











interstices transversely rugulose and conspicuously uniseriate-punctate
