the apex is siibpubesceufc, but smooth and shining. The meso- 

 sternum is strongly punctured ; metasternum and episterna clothed 

 with short pubescence, but very thinly. Abdomen shining. The 

 palpi are pitchy, the maxillary ones paler at their tips, which are 

 sharply acuminate. 



I have some doubts as to what genus this insect is best placed in. 

 Thanasinms, as it now stands, is a complete magazine. Comparing 

 this insect with T. formicarius, the antennae are rather long, and 

 are in the middle wider and flatter, the apical joint rather larger and 

 less cultriform ; the head, trophi, eyes, thorax, form of the elytra, 

 &c. agree fairly well ; the femora and tarsi appear to me also to 

 agree sufficiently well. 



Two specimens were obtained.

The head in this little species is ^ider than the thorax and 

 thicklj^ clothed with silvery shining hairs ; the eyes are large and 

 oval and finely faceted, with numerous setose hairs ; the antennae 

 are very short, reaching scarcely to the middle of the eyes, almost 

 white. The thorax is wide in front, with a deeply impressed 

 transverse Hne just behind the front margin, the sides strongly 

 lobed immediately behind this line ; the lobes with a small fossa on 

 each, then much contracted to the constricted base. The elytra are 

 about the same width as the head, parallel, almost variolose, the 

 small callus, and a variable spot nearer the scutellum, often the 

 whole base, is indeterminately white ; the rest dull black, thickly 

 clothed with short shining hairs. The legs are rather variable ; 

 the tibiae except at the apex, the femora except at the bases, are 

 dark pitchy ; but the hind femora are sometimes quite testaceous, 

 the tarsi are short. This species differs from N. despectus in the 

 form of the thorax and with the following species will probably 

 ultimately be separated generically ; at present the points of re- 

 semblance — the structure of the antennae and head — justifv its 

 association with it. 



Several specimens.
