Malacoderm Genera Prionocerus and Idgia. 371 
tip, and the palpi also, testaceous ; the head and prothorax 
closely, minutely, the elytra densely, rugulosely punctate, 
the latter with seriately-arranged raised granules extending 
down the disc. Head somewhat produced in front, narrow ; 
eyes moderately large, distant, emarginate; apical joint of 
maxillary palpi elongate-triangular ; antennz very slender, 
long, joints 4-6 gradually increasing, and 7-10 rapidly 
decreasing, in length, 3 and 4 subequal in length, 11 as long 
as 10, constricted at the middle. Prothorax a little longer 
than broad, the sides rounded anteriorly and feebly sinuate 
before the base, the disc canaliculate. Elytra long, sub- 
parallel, much wider than the prothorax, rounded at the tip. 
Legs long, very slender; tarsal claws widened in their basal 
half. 
Length (excl. head) 5, breadth 11 mm. 
Hab. Burma, Karen Mts. (Doherty). 
Six examples. This species has the general facies of a 
Dasytes, from which it is readily distinguished by the 
emarginate eyes, a character bringing J. dasytoides into the 
“ Prionocérides ” of Lacordaire. In the absence of the male, 
it can remain under Jdyia for the present, the Chinese 
I. flavirostris, Pasc., having similar tarsal claws, slender 
legs and antenne, a small head, &c.
