180 j\Ir. II. W. Bates oa the Longicorn Coleoptera 



The females of some of the species resemble Oncideres very 

 closely; and almost the only feature by which their generic 

 position may be recognized is the peculiar dark patch, streaked 

 with paler colours, which exists on the apical part of the elytra 

 of all the species. The head is broad, very little broader in the 

 females than in the males ; but the forehead is not so plane or 

 so much elongated as in Oncideres. The basal joint of the an- 

 tennae forms a smooth ovate club ; the thorax is relatively a little 

 longer than in Oncideres ; the elytra are free from ridges and 

 tubercles, and are obtusely rounded at the apex ; the claw-joint 

 of the tarsi is moderately elongated, and is about equal in length 

 to the remaining three. 



1. Eudesmus ruhef actus, n. sp. 

 E. cylindricus, convexus, rufescens ; thorace nigro-lineato ; elytris 



dimidio basali grisescente, apice utrinque macula magna ovata 



saturatiore strigis nigris et griseis ornata. Long. 7|-9 lin. S $ . 



Head reddish tawny, vertex streaked with black ; front plane, 

 coarsely punctured, dingy grey ; eyes oblong, one-half the length 

 of the front ; antenniferous tubercles in the male acute on their 

 inner sides. Antennae about the length of the body, reddish 

 tawny; apices of joints, from the fourth, blackish. Thorax 

 cylindrical, of same width as the head, very uneven, especially 

 on the sides, where the inequalities rise to broad, obtuse tuber- 

 cles ; colour pinkish red, centre with two black lines continuous 

 with those on the vertex, sides each with two or three much- 

 broken and oblique lines. Scutellum and basal margin of ely- 

 tra reddish, spotted with black. Elytra cylindrical, convex, 

 abruptly declivous near the apex ; surface uneven, with faintly 

 raised lines, thickly punctured, especially towards the base, 

 basal half occupied by a large, triangular, common, dingy-gTey 

 patch ; on this follows a belt of pale greyish red, which broadens 

 greatly on the lateral margins; the apical portion of each elytron 

 is occupied by a dark, neatly limited, oval patch, streaked longi- 

 tudinally with black, tawny red, and grey. Body beneath and 

 legs reddish brown ; breast ashy in the middle. 



Ega, clinging to dead boughs of trees ; rare. 



3. Eudesmus caudalis, n. sp. 

 E. cylindricus, depressiusculus, cinereo-brunneus ; thorace postice 

 fusco notato ; elytris dimidio basali griseo-fusco, apice utriuque 

 macula magna ovata nigricante fulvo strigata, medio cinereo las- 

 ciata. Long. 5|-6 lin. c? $ . 



Very closely allied to E. rubefactus, and scarcely differing in 

 the disposition of the colours and markings of the elytra. The 

 latter, however, are much more depressed ; and the insect is of a
