ON EISTERIDJB COLLECTED IN COCHIN CHINA BY 

 MONSIEUR DALAUNAY. 



BY GEOEQE LEWIS, F.L.S. 



At the request of Monsieur A. Grouvelle I have lately deter- 

 mined the names of the Histeridae collected in Cochin China by 

 Monsieur Dalaunay ; only one requires a description. The species 

 are Platysoma Confucii, Mars., MarseuU, Cand. (odiosum. Mars.) ; 

 Sister cliinensis, Mars., lutarius, Er., squalidus, Er., ccelestis, Mars. ; 

 Epierus Dalaunayi, n. sp. ; Saprinus ovalis, Mars., since, Mars. ; and 

 Faromalus Khongius, Mars. The collection is thus seen to be a very 

 small one, and as it contains only three or four sub-cortical species, it 

 can hardly be called a representative one of the region of enormous 

 forests in which it was gathered. The Hisieridce are not a very 

 attractive Family to entomologists generally, and I have no doubt 

 M. Dalaunay paid more attention to other groups. I have much 

 pleasure in naming the new species after him. 



Epieeus Dalaunati, n. sp. 



Ellipticrts, convexus, niger nitldus, antennis pedibusque rvjis ; f route 

 inter oculos parum convexa, clypeo impresso ; pronoto stria marginali integra 

 tenuiter punctulato lateralibus punctis majoribus intermixis ; elytris striis 

 tenuiter crenatis, 1 — 4 integris, 5 — 6 basi abbreviatis, interstitiis evidenter 

 punctulatis ; propygidio parce et grosse pimctato, pygidio apice Icevi ; pro- 

 steryio angustato bistriato, striis sub-parallelis antice leviter divaricatis ; 

 mesosterno late emarginato, stria integra antice tenue impressa, subtilissim 

 punctulata ; tibiis aiiticis serrulatis, posticis ciliatis. Long., 2J mill.

This species is an interesting addition to the genus, as the known 

 species from Asia are very limited in number. Among the Asian 

 species it is remarkable for its elliptical outline and convex form, and 

 for the large punctures on the propygidium. The pygidium also has 

 a few smaller punctures at its base, which gradually lessen in number 

 until they leave the apex smooth.

Note on llouoplius piuguis, Lewis, Ent. Mo. Mag., xvi, p. GO, 1879. — Mr. 

 Peringucy last year described this species as Saidixter {Marseulia) singularls, in the 

 Tr. S. African Phil. Soc, iv, p. 87, but there is no doubt it is a true Monoplius. 

 There are only slight differences between MoiiO])lius pingids and infiatus, Marseul, 

 except the colour and the elytral sculpture. Tlie elytral sculpture of flnguis some- 

 what resembles that of Margarinoius scaler, F., in its series of smooth spaces, but
