Arsipoda m<srens. 



Late ovata, convexa, nigra, nitida, tarsis posticis, pedi- 

 bus anticis quatuor antennisque sordide flihds, his apice 

 piceis; thorace tenuiter punctato, iitrinque basi obsolete 

 impresso ; elytris regulariter piinctato-striatis, punctis 

 apicem versus tenuiter impressis ; interspatiis planis, minute 

 sed distincte punctatis. 



Var. A. Abdominis apice piceo. 



Long. 2| lin. Hab. — Mysol : var. A. New Guinea 

 (Dorey). 



Head trigonate, not longer than broad ; vertex nearly 

 impunctate, very minutely rugulose ; front impressed on 

 either side with a very deep groove, which, extending along 

 the upper and inner margin of the eyes, curves abruptly 

 just before reaching the middle of the latter, and extend- 

 ing directly inwards to join its fellow immediately above 

 the apex of the carina ; encarpte well-defined, transverse, 

 naiTow, elongate, separated by the apex of the carina; the 

 latter compressed anteriorly, its upper two-thirds flattened, 

 narrowly wedge-shaped, its apex truncate ; antennae about 

 half the length of the body, filiform, the three outer joints 

 fuscous. Thorax three times as broad as long ; sides 

 nearly straight and slightly converging from the base to 

 the middle, thence slightly rounded and more quickly con- 

 verging to the apex, anterior angles thickened, obtuse ; 

 basal margin sinuate on either side near the medial lobe, 

 the latter obtusely truncate ; upper surface finely punc- 

 tured, impressed on either side at the base with an ill- 

 defined, shallow fovea. Elytra rather broader than the 

 thorax, very slightly attenuated towards the apex, convex, 

 regularly punctate-striate, the striae rather strongly punc- 

 tured before the middle, much more finely so toAvards the 

 apex ; interspaces finely punctured. Hinder thighs strongly 

 thickened ; hinder tibia? slightly incurved, the outer sur- 

 face bicanaliculate. Apical segment of abdomen trilobate, 

 the middle lobe longitudinally grooved. 



The present and the fblloAving species differ from the 

 typical form of Arsipoda in having the hinder tibias less 

 excurved at the base, 



Arsipoda Wallacei.
