2. Glenns liatesi, n. sp. Kiifus, capitc nifb-tcstacco, 

 thorace elytrisque sang'uineo-tomentosis, abdomine nigro- 

 subfBneo, segmentis singulis transversim vix siniiatiin i-iifo- 

 marginatis, crebre subtiliter punctatis. Long. corp. 13 lin. 



Closely allied to G. Chri/sis, Grav., but distinguished 

 therefrom by the redder colour of the pubescence on the 

 thorax and elytra, and by the much more closely and 

 finely punctured liind body; the transverse red markings 

 of segments 3 — 5 are nearly straight. 



Tapajos ; two specimens. 



Obs. — I have also an iudi\ idual of this fine species in 

 my collection, labelled " lirazil." A fully extended large 

 individual attains sixteen or seventeen lines of length.

 very easily removed. Scutellum black, dull and velvety. 

 Elytra not longer than the thorax, of a peculiar dull-red-
