NOTES ON MELANDRYIDAE (4). 



{Continued from Vol. LII. p. 157, 1916.) 



BY a. C. CHAMPION, F.Z.S. 



I liave recently had occasion to examine the type of the Japanese 

 genus Omineus Lewis [Ann. & Mag. Nat. Hist. (6) xvi, p. 119, July 

 iSO.j] and find that it belongs to the Heteronierous-grou}) " M^'cterina," 

 as defined by me (Ent. Mo. Mag. Hi, p. 101). The author referred the 

 genus to the Malacoderm-group " Mel3'rini," the 5-, 5-, 4-jointed tarsi 

 notwithstanding, which are clearly shown in his tig. 10 on plate vi.* 

 The type of Oinitwits., O. liumcralis Jjewis, from Japan, is so closely 

 related to Phalysiiis Champ., tj^pe P. caevuleiis Champ., from Perak 

 {I.e. pp. 150, 157, pi. ii, tigs. 15, 15 r^), that the latter generic name 

 may have to be sunk as a synonym when other new forms ai'e discovered, 

 the diiferences being partly bridged over by a Singapore insect I'ecently 

 received b}^ the British Museum. "^I'lie Japanese O. luu)ieralis has 

 exti'emely short antennae, and a narrow, bi-impressed prothorax, which is 

 more feebly margined at the base than in F. cacrtdcits ; the ventral 

 6 characters, however, are very similar, O. humeraliti having a })romi- 

 nent fulvo-pubescent tubercle in the middle of the second ventral 

 segment (not mentioned by Lewis), which is represented by a tuft of 

 fulvous hairs in P. caerideus. The opportunity^ is here taken to describe 

 the above-mentioned Singapore insect. Mr. Baker has also sent various 

 Malayan species of the allied genus Coiioi/iorj)IiNs to the Museum, but 

 these must be left unnamed for the present. 



O milieus iiicnnus, n. s]^ 



$ . Elongate, narrow, widened posteriorly, rather couvex ; piceous, the 

 labrum, the basal joint of the antennae, and the legs in part, reddish, tliiddy 

 clothed with tine cinereous pubescence ; the upper surface densely, very tinek, 

 subrugulusely punctate, subopaque, the elytra with an indication of t^hallow 

 impressed lines on the disc, the ventral surface shining and with the punc- 

 turing a little sparser. Head short, broad, the eyes extremely large; antennae 

 very short, extending to slightly beyond the anterior margin of the prothorax, 

 thickened outwards, joints 7-10 strongly transverse, 1 and 2 also stout. Pro- 

 thorax short, slightly broader than the bead, strongly transverse, rounded at 

 the sides, very little wider at the base than at the apex, transversely, inter- 

 ruptedly bi-impressed across the middle of the disc, the base bisinuate and tiiiely 

 margined to near the hind angles, wliicli are obtuse. Scutellum transverse. 

 Elytra very long, at tlie base a little broader than the prothorax, widest at about 

 the apical tJiird, separately rounded at the tip. JBasal joint of posterior tarsi 

 as long as the others (2 4) united. 

 Length 4 nun.
