624 Longiconda Malayana. 



Narrow, moderately elongate, ashy; prothorax elon- 

 gate, slightly ovate with two black median spots ; scutel- 

 lum nearly semicircular; elytra black, with four ashy 

 bands, the first basal, the second running very obliquely 

 upwards to the scutellum, the lower part a little curved 

 externally, the third band below the middle, throwing up a 

 long narrow triangle at the suture, the apex of which 

 touches the second band, the fourth apical, apices with 

 the outer angle strongly produced ; body beneath dull 

 ashy, the bases of the abdominal segments brownish- 

 black ; legs grayish-brown ; antennee brownish-ashy at 

 the base, gradually paler outwardly. 



Length 6h-8 lines. 



This species may be a modification of Olytus elongatulus. 

 Lap. et Gory, but with every allowance for possible 

 variation, it scarcely accords sufiiciently with either their 

 figure or description. 



Demonax detortus. 



D. modice elongatus, cinereus ; prothorace oblongo- 

 globoso; elytris nigris, fasciis quatuor cinereis,

 medio triangulariter ascendente, tertia semicircularij 

 quarta lata apicali. 



Hah. — Sarawak . 



Moderately elongate, ashy; prothorax oblong-globose, 

 with two round black spots before the middle ; scutellum 

 transversely triangular, a little rounded at the point; 

 elytra black, with four ashy bands, the first basal, sending 

 down on each shoulder a long narrow pointed stripe, 

 the second forming an elongate triangle, its apex 

 touching the scutellum, the basal angle on each side 

 throwing out a slender curved line, the third band arched 

 anteriorly, nearly semicircular, the fourth rather broad, 

 apical; body beneath dull ashy; legs brownish-gray; 

 antennee with the first four joints blackish, the rest 

 grayish- white. 



Length 6| lines. 



This species has a prothorax more inclining to glo- 

 bose; the black interval between the first and second 

 bands takes the form of the letter W, or rather of two 

 W'Sj the interruption occurring where the apex of the 

 triangle of the second band joins the scutellum.
