37. ScydnKjenus pygmoius, N. 



S. statura et colore praecedentis sed longius pubescens et sesqui 

 minor ; long. corp. ^ lin. Antennae art. 3 et 4, 5 et 6 inter se 

 subaequalibus, 7° majore, ovato, 8-10 subglobosis, fortius com- 



. pressis, cum ll'' clavam formantibus, hoc magno, obconico, apice 

 obtuso. Palpi maxill. art. 2" tenuiore, ?>^ inverte conico, 4° mi- 

 nute. Mandibulse obsolete unidentatae. Thorax conicus, latitu- 

 dine parum longior, elytris fortiter applicatus, basi 2-sinuatus et 

 4-foveolatus. Pedes et elytra praecedentis, his tamen amplioribus. 



Strongly allied to the two preceding species, but very much 

 smaller, more compact, and covered with longer hair, — thus of 

 rather a different appearance regardless of its size. From S. pu- 

 bescens this species would principally differ in the shape of the 

 seventh antennal joint, also in that of the first three club-joints, 

 which are much more compressed and more hairy in S, pygmceus. 

 The thorax of the latter is more firmly applied to the base of the 

 elytra, the latter have a fuller and more robust appearance about 

 them, the palpi are more slender, and the tooth of the mandibles 

 is pointed. From S. advolans it would principally differ, besides 

 the generalities mentioned above, in the shape of the thorax 

 and in some of the points in which it differs from S. pubescens, 



b. Occiput narrowed. 

 38. Scydmcenus glanduliferus, N. 



S. robustus ; long. corp. f lin. Antennae art. 3-7 sensim majoribus, 

 8-10 globosis, fortiter compressis, cum \\^ glanduliformi clavam 

 formantibus, longe ciliatis. Palpi max. art. 2° tenuiore, 3° inverte 

 conico, 4° mediocri. Thorax conicus, latitudine basali baud lon- 

 gior, elytris fortiter applicatus, basi 2-impressus, in impressionibus 

 2-foveolatus. Tarsi art. 2-3 subaequalibus. 



Of the size of S. advolans and the plump shape and colour of 

 S. pygmceus , the latter being rather lighter than that of ^. advo- 

 lans ; it has the longer hairy vesture of the former (especially on 

 the occiput and thorax). The occiput is slightly narrowed be- 

 hind. The antennal club is composed of four joints, the first 

 three of which are strongly compressed, the fourth being plump, 

 and of the shape of an acorn with its cup ; all are strongly 

 ciliated. The thorax is conic, firmly applied to the base of the 

 elytra, as in the preceding species, depressed, and with two pits 

 at the base, posterior margin with two sinuosities. The shoulder- 

 ridges of the elytra are short, but rather strongly marked. 

 The tibiae are narrowed, subcylindric, and hairy at the apex. 

 Joints 2-3 of the tarsi are subequal, the anterior pair more, the 

 intermediate less contracted.
