EPIPOCUS.— ANIDEYTUS. 125 



elytra, and the thicker punctuation of both the thorax and elytra (especially the costation 

 of the latter in the female), and other minor differences indicate, I think, a distinct 

 species. 



14. Epipocus sallsei. (Tab. VII. fig. 15.) 



Epipocus Sallei (Guerin, ined., coll. Salle) . 



Oblongus, elytris ovatis, piceus, nitidus, prothoracis elytrorumque marginibus modice explanatis et reflexis ; 

 antennarum articulo basali et apice, prothoracis lateribus, elytrorum macula parvula humerali, apiceque 

 abdomine et pedibus rufo-ferrugineis, tibiis (apicibus exceptis) piceis. Long. 9-10 millim. 



Hab. Mexico, Jacale (Salle), Jalapa (Edge). 



Head pitchy, the front, mouth, palpi, and the basal and two or three apical joints of 

 the antennae red. The latter nearly half as long as the body, their third joint elongate, 

 nearly or quite equal to the fourth and fifth united, the ninth and tenth joints very 

 little produced on the inner side ; all the joints finely pubescent. Thorax transversely 

 squarish, not deeply excavated in front, and with the anterior angles rather blunt, the 

 surface pitchy-black, the sides broadly red, expanded, and nearly smooth, the disc 

 obsoletely punctured, the basal sulci indistinct ; on each side of the pitchy part of the 

 disc is a tumid dark spot. Elytra much wider than the thorax, moderately convex, 

 their margins a little expanded, the epipleurse very wide at the base, their disc closely 

 and very finely punctate ; pitchy-black, a small portion of the margin at the shoulder 

 and the apex red. Underside rufous, the breast and the base of the abdomen pitchy. 



This insect will no doubt form the type of a new genus. It is allied to Epipocus by 

 the elongate third joint of the antennae, and by the form of the prosternum ; but it has 

 the appearance of an Anidrytus, and the epipleurae are very wide and quite different 

 to those of any other species of either genus. As the four specimens seem all to be 

 females, I do not think E. sallcei should at present be separated. 



ANIDRYTUS. 



Anidrytus, Gerst'acker, Monogr. Endom. p. 256 (1858) ; Gorham, Endom. Eecit. p. 21 ; Chapuis, 

 Gen. des Col. xii. p. 122. 



This genus is more numerous in species in the southern than in the northern conti- 

 nent of America, and is, so far as we know at present, confined to the tropics. The 

 species are less pubescent than those of Epipocus, and are usually of a uniform black 

 or chestnut-brown colour. They are found associated with fungoid growth on dead 

 and fallen trees. 



About twenty species have been described ; they are, like those of Epipocus, closely 

 allied to each other and hard to discriminate.
