of elytra ; under-surface witli a few scattered l)lack setic, a patch 

 of yellowish scales on middle of anterior part oi three last ventral 

 segments. 



Rostrum Ijroad, short, not concave ; the middle rather flat ; 

 external ridges diverging in front, flattened ; a short deep 

 oblique impression on each side of base, lightly connected behind, 

 and forming a horseshoe-shaped impression. Head broad, thick, 

 convex ; front a little flattened behind rostrum. AntenniB 

 slender ; the scape very little thickened to apex. Protliorax 

 broader than long (5|- x 6| mm.), dilatate on sides, widest before 

 the middle, as vifide across apex as across base, lightly convex 

 transversely, not convex longitudinally ; disc depressed : anterior 

 margin strongly sinuate : middle not projecting above head; base 

 truncate ; granules large, une()ual, rather flat, separate, uni- 

 setigerous (the setiB black and small) ; sides granulate, and rough 

 to the coxas ; a narrow space along anterior margin free from 

 granules, setigero-punctate, and declivous. Elytra oval (14 x 5|^ 

 mm.), widest about middle, transversely and longitud,inally con- 

 vex ; disc not flattened ; base hardly emarginate ; shoulders ad- 

 vanced in a strong, obtusely conical projection ; apex without 

 sinuosity or projections near suture ; sculpture formed of sub- 

 foveiform depressions and irregular transverse wrinkles separated 

 by intervals, these depressions and intervals arranged in longi- 

 tudinal lines, and forming stri;e and interstices ; the sculpture 

 more regular behind and on sides ; striie deep, uneven, the course 

 of two next suture interrupted and confused, tln-ee next more 

 even ; first three interstices indeterminate and commingled, 

 fourth hardly separated from them, fifth and sixth consisting of 

 closely-set regular elevations ; the surface of the elytra sparsely 

 sprinkled with fine black setie. Three last ventral segments 

 wrinkled at the sides ; apical segment not as long as two pre- 

 ceding ones together, a deep narrow fovea at apex. 



Length, 22 ; breadth, 7| nnn. 



Habitat. — 



This species differs conspicuously from T. obsmirus, SI., female, 

 in having the elytra very convex longitudinally, and without 

 projections or sinuosity at apex, &c., &c. It may be possible that 

 T. noctis is the female of T. insignis, SI., but I do not think 

 there is any reasonable probability of such proving to lie the 

 case; however, until both sexes of this or some closely allied 

 Amycterid are known, it is impossible to speak with certainty 

 of the sexual differences in this group of Talaurinus. The 

 differences from the male of T. convexus, SL, are too decided for 

 there to be any possibility of its being the female of that species. 



Talaurinus insignis, n. --^ji. 

 Male. — Elongate, subparallel ; prothorax very dilatate on sides, 

 granulate ; elytra foveo-striate ; legs long ; antenna3 slender.
