Genera and S^pecies of Coleoptera. 331 



obcordate yellowish spot on the vertex, descending befrn'een the eyes 

 but not passing beyond them ; antennas nearly three times as long as 

 the body in (^, black, the intemiediate joints greyish at the apex; 

 prothorax as long as broad, an in-egidar patch on the disk, apparently 

 made up of smaller spots, and occupying its whole length, occasionally 

 two or three smaller spots at the side ; scutellum small, triangidar, 

 black ; elytra short, broadly ovate, greyish yellow, with four principal 

 spots on the disk, the shoidder, a few smaller spots at the sides (some- 

 times nearly obsolete), and several at the apex black ; legs of moderate 

 length, the anterior but little produced in c?, femora and tibiae obscurely 

 ringed with gi'ey, the basal and claw-joints of the tarsi ashy, except at 

 the apex ; side of the propectus, metasternum, and abdomen closely 

 covered with a yellow pile, a spot on each side of the segments and 

 the middle of the apical one black. Length 9 lines. 



In none of the species described above have the males a spined 

 propectus, 



DcEOTHENA [Anthiibldae]. 



Head small, not contracted below the eyes, rostrum very short. An- 

 tennae 12-jointed, very slender, much longer than the body, arising 

 from a cavity beneath and a little in front of the eye, the first joint 

 swollen at the base, gradually diminishing upwards, and terminated in 

 a truncated apex, the second as long as the first, but slenderer and 

 obconic, the remainder to the eighth inclusive subequal, filifomi, their 

 apices more or less tumid, the apical third of the ninth and three ter- 

 minal joints foi-ming an oblong slender club. Eyes large, lateral, deeply 

 emarginate beneath. Antennary cavity gi'ooved above. Epistome and 

 lip forming together a small triangle covering the centre of the man- 

 dible's. Palpi filifonn. Prothorax convex, rounded anteriorly, as wide 

 as the elyti'a at the base, the carina immediately in contact with the 

 base at the middle, but slightly and gradually diverging towards the 

 side, forming a shai-p angle at its fiexure, then continued to half the 

 length of the prothorax, where it suddenly ceases. Elytra convex, not 

 gibbous at the base. Legs of moderate length, first tarsal joint elongate. 



The insect which has served for the above generic description is 

 exceedingly like Protcedus 7noerens, Pasc* On examination, how- 

 ever, they will be found to be not even generically identical, the 

 twelve-jointed antennae and its club, composed not of three only but 

 also by part of a fourth joint, being, I believe, unparalleled among the 

 Anthribidae, and the emarginate eye and the position of the abbre- 

 viated carina being quite different in Protcedus. I do not here more 

 than allude to the enormous size of the two intermediate tarsal joints, 

 as it is just possible that that may be only a sexual character. The
