39. Scydmcenus graminicola, N. 



iSf. gracilior ; long. corp. f lin. Antennse art. 3 et 4, 6 et 7, 9 et 10 

 inter se subaequalibus, 5° adjacentibus paulo longiore, .3-7 sub- 

 cylindricis, 8 subgloboso, 9-10 fortiter globosis cum 11° clavam 

 formantibus. Palpi maxill, art. 3^ inverte conico, 4° mediocri. 

 Mandibulae apice arcuatse, medio acuminate l-dentatee, basin ver- 

 sus ^ensim dilatatce. Thorax obconicus, basi depressus, 2-sinuatus 

 et 2-foveolatus, rectangulatus. Pedes tibiis elongatis basi apiceque 

 arcuatis. 



Of the usual brown colour, legs and anteunee lighter, tarsi and 

 palpi very light ; femora nigrescent at the apex ; hairs of occiput 

 and thorax rather long, the former slightly narrowed behind ; the 

 head thus of a somewhat rhomboid form. Antennal club com- 

 posed of three joints, the first two of which are strongly globose, 

 the last being acuminated and slightly cut away on one side at 

 the apex. The mandibles are furnished with an acuminated tooth 

 at the middle, bent at the apex, and, what is rather uncommon 

 in this genus, gradually enlarged towards the base. The thorax 

 is obconic, rather longer than broad. The elytra are somewhat 

 more extended than usual in this group ; the rudimentary hu- 

 meral costse are rather prominent, they are separately rounded- 

 ofF at the apex. Tibiae more or less elongated, slightly bent at 

 the base and apex, at the latter place subcylindric and hairy. 

 Tarsi with joints 2-3 subequal, first pair slightly contracted. 

 A sexual distinction appears to be expressed in the length of the 

 tibiae, which are less elongated in certain individuals, which are 

 at the same time less robust than the others. The insect is 

 easily distinguished by its general appearance. 



40. Scydmanus pi/riformis, N. 



S. supra castaneus, subtus brunneo-testaceus, pedibus antennisque 

 dilutioribus, tarsis palpisque flavo-testaceis, antennarum clava ni- 

 gricante. Long. corp. ^ lin. 



Antennae art. 3-8 fere subaequalibus, excepto .5*^ parum longiore, 

 8° subgloboso, minore, 9-10 subglobosis majoribus cum 1 1° acuminato 

 clavam formantibus. Palpi maxill. art. 3° inverte conico, 4*^ minuto. 

 Thorax obovatus, basi 2-foveolatus. Pedes coxis 2 posticis distan- 

 tioribus ; tibiis 2 anterioribus basi apiceque leviter arcuatis, reliquis 

 subsimplicibus ; tarsis art. 2-3 subsequalibus. 



A pretty little species, at once distinguished by its colour, 

 which is chestnut, darker at the base and suture of the elytra, 

 and light, more or less brownish or yellowish, below ; the an- 

 tennae being of the latter colour, with a nigrescent club. The 

 occiput is slightly narrowed ; the head altogether plump, heavy, 

 and transverse. The antennal club is composed of three sub-
