2nd; 4 — 10 yeiy similar to one another in length, and 

 each scarcely stouter than the preceding ; the last joint 

 sinuate at the extremity. Mandibles nearly one-half 

 as long as the head. Head as broad as the thorax, the 

 hind part gradually narrowed into the neck ; it is scarcely 

 shorter than the thorax, considerably longer than broad ; 

 above it is densely and coarsely rugose-punctate, and with 

 a rather long pubescence, beneath it is very shining and 

 rather sparingly punctured ; the lateral grooves are absent, 

 but a raised, smooth space, proceeding from the base of 

 the mandible, indicates what should be the boundary of 

 the groove beneath. The thorax is elongate, about twice 

 as long as broad, about half as broad as the elytra ; it is 

 nearly straight at the sides from the base to the middle, 

 thence narrowed to the front ; it is of a shining-blue 

 colour, finely and rather sparingly punctured, with an 

 impunctate space along the middle. Elytra scarcely so 

 long as the thorax, and darker in colour, rather finely 

 and sparingly punctured. Hind body shining blue, finely 

 and rather sparingly punctured. Legs bluish, tibia3 with 

 a grey pubescence on the inside. 



Ega ; one specimen, probably female. 



2. Af/rodes longiceps, n. sp. Cyanea, nitida, thorace 

 elytrisque subtiliter punctulatis, illo elongato ; capite subtus 

 dense grosseque punctato, mandibulis hoc plus duplo bre- 

 vioribus. Long. corp. 8|^ lin. 



Allied to the preceding species, but with the head diffe- 

 rently formed, and closely and coarsely punctured beneath. 

 The antennje are nearly black, with the three basal joints 

 bluish ; the extreme base of the 2nd joint red ; they are 

 not thickened after the 4th joint, joints 4 — 10 scarcely 

 differing in length and breadth ; last joint sinuate at the 

 extremity, ferruginous at the tip. INIandibles not half 

 the length of the head. Head long and narro-\v, with the 

 eyes very prominent; it is about as long and about as 

 broad as the thorax, the hinder part much narrowed to 

 the neck ; it is above densely rugose-punctate, of a violet 

 colour, not shining, with a rather dense pubescence ; 

 beneath it is very shining, closely and very coarsely punc- 

 tured, without any trace of lateral grooves. Thorax 

 considerably more than half the width of the elytra, 

 nearly twice as long as broad, nearly straight at the sides
