ItSi! Mr. J. Nietiier on new Ceylon Colcoptera. 



of the said carina, differing, however, from it in general appear- 

 ance. The colour is that of S. alatus, but a shade or two darker, 

 the insect being at the same time larger and altogether more 

 robust. The eyes are small. Antennal club three-jointed, the 

 joints forming it gradually increasing in size, obovate, flat at 

 the base, the last acuminated. Scutellum obsolete. Elytra with 

 two slight basal impressions, the traces of a humeral costa, sepa- 

 rately rounded-off at the apex. Legs elongated as usual ; two 

 posterior coxse distant ; tibife straight, subcylindric, but not nar- 

 rowed at the apex, the four anterior ones hairy ; tarsi with joints 

 1-4 almost imperceptibly decreasing in size, or perhaps 2-3 

 equal, the anterior ones slightly contracted, these and the inter- 

 mediate ones hairy on the inside. Mesosternal carina middling, 

 flat on the back, with a shallow, but very distinct, longitudinal 

 groove or excavation, anterior part projecting, acuminated. 



34. Scydmcmus pselaphoides, N. 



S. subpyriformi-ovatus, subconvexus, magis minnsve brunneiis, pedi- 

 bus antennisque subtestaceis, femoribus apice nigvescentibus, tarsis 

 palpisque testaceis ; flavo-pubescens. Long. corp. 1-li lin. 



Antennae art. 1° mediocri, apice biacuminato, 2-4 sensim niinori- 

 bus, 5 et 2, 6 et 3, 7 et 8, 9 et 10 inter se snbaequalibus, 9-11 cla- 

 vam formantibus, 6-11 basi rotunda trunratis, 6-8 apice oblique 

 truncatis, 7-8 corapressis, 9-11 obovatis. Mandibulse dente bifido 

 munitse, basi dilatatse et ciliatse. Palpi maxill. art. S^inverte conico, 

 4° minimo apice truncato. Thorax obovatus, latitudine quarta parte 

 longior, basi 4-foveolatus. Elytra apice singulatim rotundata. Pedes 

 validi, tarsis art. 1-4 gradatim minoribus, anterioribus dilatatis, his 

 cum intermediis subtus fortius pilosis. Mesosternum prsecedentis. 



An anomalous species with regard to its general appearance, 

 which differs considerably from that of the rest of the group, 

 and makes it, as I have remarked above, the connecting link 

 between this and the following group. This is the largest spe- 

 cies I have hitherto met with. The system of coloration is the 

 usual one, — more or less deep brown, legs and antennae lighter, 

 tarsi and palpi very light. Eyes middling. Antennse with a 

 3-jointed club, the joints subglobose, flat at the base, the last 

 large, conic; joints 6-8 are slightly truncated at the apex; 7 

 and 8, being at the same time strongly compressed, have a sub- 

 perfoliated appearance. The mandibles are furnished with a 

 bifld tooth. The third joint of the maxillary palpi has the sha[)e 

 of an inverted cone, the fourth minute and truncated at the 

 apex. The thorax is of an obovate form, about | longer than 

 broad, rounded-off before and gradually narrowed below the 

 middle, subquadrate at the base, impressed with four fovea? or 

 ])its, the posterior angles roundtd-off. Scutellum minute. Ely-
