IJab. Malacca, Penang [H. N. Ridley). 



One male, received at the Museum in 1874. This insect 

 has the general facies of 1. pallidicolor, ^ , as here identified, 

 differing from it in the distinctly longer, stouter, curved 

 apical joint of the antennae, the darker limbs, the simply 

 emarginate sixth ventral segment, and different armature. 

 7. atriceps, from Burma, has a more elongate apical joint 

 to the antennae, the head more produced anteriorly, the 

 femora testaceous, and a dissimilar S -armature. 



57. Idgia decolor, sp. n. 



Elongate, narrow, shining, finely pubescent, and sparsely 

 fusco-setose ; testaceous, the elytra paler and somewhat 

 transparent, the tips of the latter and the head black, the 

 antennae and legs (the bases of the femora excepted) infuscate. 

 Head elongated anteriorly, the labrum about as long as 

 broad ; eyes very large, contiguous in ^ , narrowly separated 

 in ? ; antennfe long, slender, joint 11 sinuate, concave 

 within, about one-half longer than 10. Protliorax longer 

 than broad, slightly wider than the head, sinuate at the sides 

 posteriorly. Elytra long, densely, finely punctate, 



(J . Anterior tarsal joints 1-3 with a comb along their 

 inner edge ; sixth ventral segment triangularly emarginate. 

 Genital armature (PL XII. fig. 47) : lateral lobes long, rather 

 narrow, feebly curved, blunt at the tip ; median lobe very 

 long, slightly sinuate, drawn out into a short, curved point 

 at apex. 



Length (excl. head) 8-10, breadth 2|-3 mm. (cT ? .) 



Hab. Burma, Karen Mts. {Doherty^ type : (^ ? ) ; Tenas- 

 SERIM, Tavoy {Doherty : ? ). 



One male and six females. Separable from its allies by 

 the pallid, somewhat transparent elytra, with small apical 

 spot, tlie elongate black head, the infuscate anteunae and 

 legs (the bases of the femora excepted), and the $ -armature, 

 which is very different from that of the allied Burmese 

 1. atriceps, the latter also having a relatively longer apical 

 joint to the antennae. One of the females from Tavoy with 

 wholly pale head (eyes excepted), and another (immature) 

 with the legs and antennae also testaceous, doubtless belong 

 to the same species. 



* In the figure it is removed from its in-oper position and shown from 

 the ventral aspect.
