patch of coarse pni\cUi;-es on each side of the groove. Under parts 

 green Avith ajiieous reflections. 



Femora green and covered with minute crowded warts ; tibiae and 

 tarsi hght rnfous, the tibiae with elongated papillje and short hairs. 



Hub. Mexico. 



Of this species there are two examples in the Museum ; in the one 

 a purplish red tint pervades all the joints of the antennse but the 

 first, and extends over the whole elytra excepting on the basal mar- 

 gin and the extreme edge, which are green. 



Tliis species seems to link the three genera Pyrodes, Mallaspis, 

 and Solenoptera ; it agrees in most particulars wth Pyrodes. 



Pyrodes Smithianus. 



Scutellum considerably elongated at the point and notched at the 

 base, the shoulder and the elytra close to the scutellum are produced, 

 and near the shoulder there is a deep groove. The head and thorax 

 are rather smooth and closely jninctured ; the front margin of the 

 thorax is slightly notched in the middle ; the scutellum is qiute smooth 

 on the edges, down the middle, and at the tip ; the elytra are roughly 

 punctured, the punctures often running together and forming cha- 

 racters like letters ; there are four longitudinal ribs down each, which 

 are branched at the end. 



This Pyrodes is of a bronzy copper colour, the tibiae and most of 

 the joints of the antennse being tinged mth purple. 



Hub. Brazil. 



A specimen was found by J. P. George Smith, Esq., of Liverpool, 

 on Caripi, an island thirty miles from Para : be presented it, with 

 numerous other fine insects, to the British Museum. 



Calloctenus, n. g. 



Body small, the elytra extending over its side and considerably be- 

 yond its extremity. Head much excavated in front. Eyes large and 

 prominent. Thorax with a distinct tooth on the sides a little beyond 

 the middle. Scutellum of an elongated triangular form, pointed at 

 the end. Elytra spined at the suture and at the end of the lateral 

 margin. 



Antennse in the male pectinated from the fourth joint, in the fe- 

 male serrated from the fifth : in the male the first joint is of the same 

 length as the fourth exclusive of the appendage ; the third is consi- 

 derably elongated and with a protuberance at the end ; from the 

 fourth to the eighth the end is furnished with a compressed appen- 

 dage narrow at the base, dilated afterwards and blunt at the tip (the 

 ninth and other joints broken off). Antennse in the female with the 

 terminal joints depressed, oblique at the end, so that the inner edge is 

 serrated. Legs moderate, simple, without serratures. Elytra spined 

 at the suture and at the end of the lateral margin. 



This genus comes between Pceci/osoma and Anacolus. 



Calloctenus pulcher.
