^ . Black, shining, above and beneath veiy densely and distinctly 

 punctured : first joint of the antennae and the rostrum, piceous : tarsi 

 pale yellow piceous. Tylus remotely punctured towards the base, im- 

 punctate before the middle, transversely rugose : thorax in the middle 

 almost twice longer than the head, convex towards the sides, behind 

 the middle, and anteriorly transversely slightly depressed, somewhat 

 convex before the middle, this convex part somewhat depressed in the 

 middle, anteriorly somewhat sloped : clavus with two rows of punc- 

 tures : corium in the interior part behind the middle with four rows 

 of punctures, towards the base, and on the exterior part sparsely punc- 

 tured : membrane fuscous, (Stal). Long, 4 J : broad, 2 mill. 



Reported from Tranquebar, India, Saigon.

Second joint of the antennae much smaller than the third : plaques 

 mates of the episternums small : lobes of the head, unequal or equal which 

 causes the anterior margin to appear more or less emarginate : tylus 

 almost as long as the juga. Head slightly reflexed on the margins and 

 ajDpearing impressed or more or less emarginate in front : pronofcum ap- 

 pearing flattened in the margins although really possessing a marginal 

 ridge : median angles of the presternum less pronounced than in the other 

 genera of this section and therefore the median groove is not so deep : 

 mesosternal ridge indistinct, metasternum smooth : ostiolar canal with 

 an ear-shaped small tongue very distinct, the dull plates (plaques mates) 

 weakly developed above and below the mesosternal groove (Sign.).

More or less oval : bluish-black, shining, punctured, spotted 

 white ; two irregular spots on the anterior angles of the pronotum, 

 two others at the external base of the hemelytra and two not so large 

 at the external angle of the corium : usually also two small white dots 

 at the external angle and at the base of the pronotum as in the type, 

 white : head indented in front, juga with a channeled rim : feet blu- 

 sh-brown, with a more or less broad white ring at the base of the tibiae :
