tion deep, not quite extending to the margins, elytra rather strongly 
and closely punctured, the apex not produced into a tooth, the 
second abdominal segmént furnished with two short, closely approa- 
ched appendages, the first joint of the posterior tarsi as long as 
the following two joints together, claws bifid.

11. simplicipennis differs but little in shape and colour from 
several other species of the genus, but can only be compared on 
account of its uniform flavous coloration to Æ7. ceylonensis Jac., 
1H. longicornis AI. and 77. rostripennis AI]. ; from the first named, 
the species is distinguished by the want of the elytral costæ, from 
the second by the much shorter antennæ ; the want of the tooth 
at the apex of the elytra, and the absence of the two longitudinal 
sulci at the sides of the latter, separates the species from 
1. rostripennis. The penis is very similar in sbape to that of 
H. abdominalis, but instead of being rather suddenly constricted 
into a strongly curved point, is gradually narrowed and less 
strongly curved; in the female the last abdominal segment is 
deeply excavated at the apex and the latter is broadly rounded and 
produced at the middle; numerous specimens were obtained, which 
prove constant in the above particulars. 
Haplosoma costatipennis n. sp. 
Fulvous, abdomen black, elytra finely punctured, the sides with 
a longitudinal costa, the apical angle dentiform. 
Length 3 1/2-4 lines. 
Head impunctate, the antennæ extending below the middle of the 
elytra, the third and fourth joints equal, elongate, thorax one half 
broader than long, of usual shape, the dise deeply transversely 
sulcate, elytra rather opaque, finely punctured, the shoulders very 
prominent, the sides with a very strongly marked longitudinal 
costa, abbreviated before the apex, the latter slightly concave and 
produced into a short tooth or point; abdomen black, the last 
segment with a short indentation at the middle. 
Hab. Madura (Madras). 
This species may be compared to Z7. ceylonensis Jac. on account 
of the elytral costæ, but in that insect the entire underside is 
fulvous and the apical angle of the elytra is not produced ; there are 
only two (apparently female) specimens before me. 
Mimastra alternata n. sp. 
Testaceous, the antennæ and tarsi obscure piceous or fuscous, 
thorax with five small piceous spots, elytra finely and closely
