genera and species of Malacoderm Coleoptera. 407 



two specimens taken by Mr. Lewis, one has rather longer 

 antennae than the other, and is no doubt the male ; they 

 are scarcely serrate in either specimen. 



It bears a strong resemblance to Eros velatus, but the 

 thorax is divided into four areolets, something as in 

 Conderis. The elytra appear firm and rather flat, with 

 the four costae evenly raised, but the 1st and the 3rd 

 terminate before the apex. 



Pristolycus, n. g. 



Caput oculis mecliocribus, antennis quam corpus brevi- 

 oribus, leviter serratis, 11-articulatis. Thorax trans- 

 versa, antice angustatus, angulis posticis prominulis 

 subacutis, marginibus parum reflexis, disco obsolete 

 crebrius punctato, leviter et obsolete canaliculate Scu- 

 tellum integrum. Elytra haud reticulata, creberrime 

 confluenter punctata, costis tribus ante apicem desinenti- 

 bus. Pedes mediocres, tarsi quinque-articulati, articulo 

 tertio obconico, quarto subtus longe lamellato. 



Pristolycus sagulatus, n. s. (PI. XVII., fig. 8). 



Niger, subnitidus, prothoracis marginibus antice piceis, 

 elytris roseo-miniatis, prope suturam infuscatis, margine, 

 sutura et costis nigris, scutellum nigrum punctulatum.

The very remarkable insect for which I propose this 

 genus has the general appearance of being one of the 

 Lycidce. It presents, however, so many points in which 

 the structure is divergent from the family that its 

 position is doubtful. The antennae are closely inserted 

 on the front of the small head, which is sunk in the 

 prothorax. The maxillary palpi have their apical joint 

 cylindrical, and the labial are small, not enlarged at the 

 apices. The middle coxae are separated only by a narrow 

 ridge of the mesosternum. The trochanters are small 

 pieces closely applied to the bases of the femora. Of 

 the abdomen I cannot speak precisely, the specimens 

 having shrunk a good deal ; they may all be females, 

 and I can only detect six ventral segments ; at all events 

 the structure is not dissimilar to that of many female 

 Lampyridce. It is black, with no indication of being 

 luminous. The prothorax has the hind angles turned
