strong, the second and third turning towards each other at the base, interstice of 

 first and second widest anteriorly, fourth apical, short, fifth apical and one-third 

 longer, straight, reaching the middle of the dorsum, sutural interstice wider than 

 the others, apical margin microscopically strigose ; the propygidium, transversely 

 punctate, median punctures oblong ; the pygidiam with a large, deep, nearly circular 

 fovea on either side, median area distinctly convex, forming a little boss ; the pro- 

 sternum without striae, microscopically strigose, anterior lobe irregularly punctulate, 

 punctures of various size and much scattered ; the mesosternum anteriorly widely 

 sinuous, bistriate at the sides, inner stria complete in front, both striae continued 

 along the sides of the metasternum ; first segment of the abdomen also laterally 

 bistriate ; all the sternal plates are punctulate, but the punctures are extremely fine, 

 scattered and evenly set. .The anterior angles of the mesosternum are minutely 

 strigose ; the legs are pitchy-red, anterior tarsal grooves nearly straight (generic 

 character), tarsi, especially the intermediate and posterior pairs, short and robust, 

 anterior tibiae 5 — 6 dentate. 



E. monticola, Lew., is a species similar to the above.

PLATYLISTER, n. g. (Type JPlatysoma ovafum, Er.). 



Gen. Platysomse approxime afflne sed multo major. Corpus depressum, 

 ovntum vel oblongo-ovatum ; mandibulis validihus, fortihus dentatis ; frons 

 concava ; prosternum haud striatum ; mesosternum antice emarginatum vel 

 sinuatum ; pygidium margine extus elevata ; tihice anticce fortiter dentatce, 

 fossa tarsali conspicue sinuata. 



The type of the genus Platysoma is P. depression of authors, and 

 I propose to separate from it the large species which are found in 

 considerable numbers in Eastern Asia and the Islands lying to the 

 west of the Pacific Ocean, under the name of Platylister. With rare 

 exceptions the species of Flatylister have the mesosternal marginal 

 stria complete. The genus Platysoma as it has stood until now con- 

 tained nearly 150 species ; Harold, in 1868, gave 82, of which at least 

 10 names are lost in synonymy, so that since the issue of the Munich 

 catalogue the number of species has been doubled, and now nearly 

 50 of these will come into the new genus. Many species of Platysoma 

 have a convex immarginate pygidium, and are very differently con- 

 structed insects to Flatysoma ovatum, Er., P. odiosum, Mars., and others; 

 and I think it will greatly facilitate the study of this somewhat obscure 

 group to divide it as I have determined. 



Plattsoma steiatisternum, sp. n. 



Ovatum, parum convexum, nigrum nitidum, punctulatum ; fronte leviter 

 impressa, stria utrinque interrupta ; elytris, striis 1 — 3 integris, 4 — 5 ahhre- 

 viatls ; pygldio utrinque transversim excavato. Long., 3f mm.
