204 MR. M. JACOBY ON NEW [Feb. 17, 



Head with an obsolete median longitudinal groove, closely and 

 finely rugose-punctate. Antennae two thirds the length of the body, 

 slender and filiform, the second joint distinctly shorter than the 

 first, the third more than twice as long as the preceding, basal 

 joint stained with piceous above, the two or three following fulvous, 

 the rest dark piceous or black. Thorax subcylindrical, scarcely 

 broader than long, the lateral margin entirely absent ; surface sculp- 

 tured like the head, obsoletely transversely depressed across the base. 

 Elytra more strongly punctured, the punctuation arranged in very 

 closely approached rows, the interspaces here and there obsoletely 

 raised, surface covered with a thick layer of white powder, when 

 rubbed shining black. Legs black, extreme apex of the tibiae and 

 the tarsi obscure fulvous. Femora armed with a smooth tooth. 



Oyama, Kiga, Oguma, Nikko, 



In size this species agrees with L. lewisi, Baly, and L. fulvus, Baly, 

 but is quite distinct from either of them. The general colour is 

 entirely black ; and the insect, when captured, is covered with a thick 

 layer of white powdery matter which entirely hides the punctuation 

 from view ; when rubbed, the elytra, unlike L. lewisi, are shining 

 black and not covered with pubescence. la the latter species there 

 is a finely but distinctly marked lateral margin to the thorax, which 

 in the present insect is totally absent; the punctuation of the head 

 and thorax also is much more finely rugose, the antennae are pro- 

 portionately longer and have the three or four lower joints fulvous. 



Genus Demotina, Baly. 



Demotina bipunctata, sp. nov. 



Narrowly oblong, obscure fulvo-piceous, closely covered with 

 white pubescence ; antennae and legs fulvous ; head, the sides of 

 the thorax and elytra, and a small spot at the middle of each elytron, 

 whitish. 



Length 1| line. 



This species, although closely allied to D. modesta, Baly, is yet 

 quite distinct. The antennae are less robust, the thorax is rather 

 more transverse, the pubesnence which covers the entire upper surface 

 is not fuscous as in the allied species, but white, covering the entire 

 head thickly, and forming a band at the lateral and anterior margin 

 of the thorax as well as at the sides of the elytra, while a small spot 

 of white hairs is placed near the middle of each elytron ; the punc- 

 tuation of the latter as far as visible seems to be arranged in very 

 closely approached rows. The intermediate tibiae are obsoletely 

 notched at their apex ; claws bitid ; femora with a minute tooth. 



Kobe. 



A single specimen was obtained by Mr. Lewis during his first 

 journey, a second one at the last visit to Japan. The species is 

 closely allied to D. modesta, Baly ; but is of smaller and less robust 

 size, and distinguished by the white pubescence in forms of stripes and 

 spots on the elytra. D. decorata, Baly, is smaller still, of different 

 coloration and with comparatively short antennae.
