 instructo, abdomine segmentis dorsalibus 6 et 7 crebrc

Allied to Homalota notha, but larger and brighter in 

 colour, and even more like a Gyrophcena, by its detlexed 

 head, and curled-up hind body ; the colouration is also very 

 much that of a Gyroplmna, The antenna are rather 

 short, considerably thickened towards the apex ; the 3rd 

 ioint is more shoH and more slender than the 2nd ; the 

 4th ioint is but little stouter than the 3rd, and not quite 

 so lono— from this to the 10th each joint is stouter than 

 the preceding one; 5 th longer than broad ; 10th evidently 

 transverse ; 1 1th joint rather thick, nearly twice as long 

 as the 10th, and rather lighter in colour. Head deliexed, 

 narrower than the thorax, pitchy, very finely and indis- 

 tinctly punctured. Thorax very short, shaped like that ot 

 a GyrophcBna, rather narrower than the elytra, more 

 than twice as broad as long, all the angles much rounded ; 

 of a pitchy ferruginous colour, almost impunctate Llytra 

 longer than the thorax, of a tawny colour, a little darker 

 at the external angle, rather closely covered with hne 

 elevated i^unctures, which are not so distinct about the 

 scutelhim. Hind body yellowish, a little darker towards 

 the apex; rather rounded at the sides, narrower at the 

 extremity; shining above, and nearly impunctate but to- 

 Avards the extremity the segments are furnished with some 

 yery fine elevated points; it is clothed on the underside 

 with a dense, fine, erect pubescence. The legs are yellow. 

 In the male the elytra are provided, near the outer 

 corner, with an elevated tubercle, and the 6th and 7th 

 segments of the hind body are furnished on the upper side 

 with numerous granulations, which are coarser on the /th 

 than on the 6th segment. 



Tapajos ; two male individuals. 



2. Brachida Reyi, n. sp. Rufescens, antennis medio, 

 capite, elytris, abdomineque ante apicem infuscatis ; tho-
