19. Acorynus tolianus spec. nov. 



S- Rostrnm, head and prothorax brown-black, apex of pronotnm and elytra, 

 and underside rufescent. Antenna brown, rufous towards base. Legs entirely pale 

 rufous. Underside, rostrum and head, scutellura, pygidinra, and markings of 

 pronotum and elytra pubescent yellow. Pronotnm with three straight vittae, the 

 lateral ones broad, incompletely separated from the pubescence of the underside. 

 A broad basal marginal band to elytra, dilated below shoulder and near suture, 

 joined to a subbasal spot which stands b-'t\veen stripes 1 aud 4 ; behind tiiis spot 

 a small dot and larger rounded spot ; at basal third of suture a transverse spot, not 

 interrupted at suture, between interspaces 3 of the two elytra, produced backwards 

 on third stripe, joining a square median spot which expands between second and 

 sixth interspace; an elongate sutnral spot before declivous apex, isolated ; a sutnral 

 and a lateral apical spot, joined together ; two nearly square lateral spots, one 

 before, the other behind middle, the second produced along margin to near apical 

 spot. Pygidium slightly brown in middle. 



Rostrnm with three abbreviated sharp dorsal carinae, the lateral ones slightly 

 converging at end. Eyes longer than broad, close together in front, bat not 

 touching each other. Segment 10 of antenna half as long again as broad, 

 9 shorter than 3 and only one-third longer than 8. Prothorax broad, rouuded- 

 angulate before base, no coarse punctnration, antemedian sulcus present, but not 

 sharply impressed, dorsal carina feebly biconvex. Elytra convex, depressed at 

 suture, basal callosity feeble, sides somewhat rounded. Prosternum irapnnctate. 

 Metasternnm with brown lateral spot on sternite. Abdomen and tibiae unarmed.

cJ. Blackish-brown, somewhat rufescent ; pubescence of underside grey, not very 

 dense. Upperside marked with clay-colour : rostrum, cheek and a dorsal stripe 

 along eye ; three straight vittae on pronotum, the lateral ones broad ; a sutnral 

 vitta on elytra, occupying basal third, then dividing into two broader stripes, one 

 on each elytrura, these strijies running oblii|uely backwards aud laterad to outer 

 apical angle of elytrum, the sutnral vitta connected at basal edge with an irregular 

 humeral vitta which extends to middle of elytrum, a few Jots between the two vitta, 

 and one on second strijje at apical fifth ; suture edged with clay from near obli(pie 

 band to near ajiex. Antenna and legs rufescent. Pygiilium clay, with lirowu 

 mesial vitta. 



liostrum short; cariuae feebly marked, abbreviated. Segments 9 to II of 

 antenna nearly as long as the others together, 8 conical, shorter than 10, this 

 one-third of 9, the latter nearly eiiualling 5 to 8 togetlier. Eyes well separated, a 

 little longer than ijniad. Protliora.x conical, witii almost straight sides, not
