(Plate VIII, fig. 1.) 



Described from a single pinned specimen from the marginal zone 

 of the Inle Lake at Fort Stedman, Yawnghwe State, 28-ii-1917. 



Head reddish-brown with a central, longitudinal, pale, impressed, 

 smooth line on disk ; antennae hairy, ochraceous, the basal joint stout, 

 curved, with sub-basal, submedial and apical fuscous annulations ; 

 second joint a little shorter than first, broadly banded with fuscous 

 a little beyond base and at apex ; third joint slender, subequal in length 

 to second and fourth, almost entirely fuscous except at base, where it 

 is pale ; 4th joint slender, with basal and apical fuscous annulations ; 

 eyes black, deeply faceted, the facets appearing silvery in certain lights. 

 Pronotum reddish-brown, the posterior area much darker, almost black 

 and thickly covered with shallow punctures and short black hairs. On 

 the anterior area there are two submarginal, bluish-grey, longitudinal 

 fasciae widening posteriorly and extending from near the anterior lateral 

 angles to a little beyond the junction of the anterior and posterior lobes ; 

 sides of pronotum distinctly subangulate, the posterior angle rounded. 

 Elytra dark brown with a large irregularly rectangular patch at basal 

 angle, narrowed towards base, a small oblong one at about middle of 

 inner margin and a reversed Y-shaped mark at apex, dull white. Dr. 

 Annandale informs me that when the insect was alive these marks were 

 of a bluish-grey tint. Underside light yellowish-brown, the prosternum 

 and the mesopleura darker, a lateral series of silvery grey spots out- 

 wardly margined with black, extending from the prosternum to the 

 sixth ventral segment, a suffusion of red on the underside of the con- 

 nexivum and on the fifth, sixth and seventh ventral abdominal seg- 

 ments. Legs hairy, luteous, annulated with dark fuscous ; coxae and 

 femora marked with red on the underside ; hind femora incrassated. 



Rostrum ochraceous, with a broad, longitudinal, black band 

 below. 



Length G millim. 



Type No. 7109/H, I. in the collection of the Zoological Survey of 

 India.
