A pair of this pretty little insect was found by Mr. Row- 

 land Taylor in 181)5, It has the general aspect of Lachnosterna 

 and BrahmiJia, from wiiich it is impossible to dissociate it in 

 spite of important divergences. Its very short and prominent 

 anterior coxae infringe the primary characteristic of the true 

 ]\Ielolonthini, with which the fused abdominal segments and 

 general structure connect it. Its most striking feature is tlie 

 enormously elongate club of the male, consisting of three equal 

 joints almost as long as the elytra. The scape is about as 

 long as the six joints forming the stipes taken togetiier, 

 these being very short, but slightly increasing in diameter as 

 tliey approach the club. In the female the club is extremely 

 short, and between it and the elongate first joint there are 

 only five joints, which are not compressed as in the male, but 

 are conjointly a little longer than the scape. The prothorax 

 is finely rugulose, tiie scutellum smooth and velvety, and the 

 elytra very irregular, with shallow depressions, variolosa 

 punctures, and strong carinaj near the apices. The organs of 

 the mouth are rather peculiar, and the claws have a strong 

 curved tooth about the middle. The legs and underside are 

 everywhere strongly punctured, and there is a greyish bloom 

 ])ariinlly covering the sterna, abdomen, and elytra.
