Rather like F. sericeus. Head, mouth, antennse, palpi, legs, and 

 body beneath black. The head is uneven and impressed between 

 the eyes, the base is nearly smooth and shining ; the antenntB have 

 the first three joints testaceous beneath, from the foui-th to the 

 tenth the joints are longer than wide, acutely produced at 

 their innei' apices. The thorax has a large black and square 

 patch on the disk and front margin ; this is somewhat produced 

 behind, but does not reach the hind margin ; the disk is smooth 

 in fi'ont, but punctured and rugose at the sides. The form is 

 like that of P. sericeus, transverse, rounded at the sides and base, 

 without angles ; finely mai-gined, and a little elevated in front. 

 The disk and the elytra are clothed with long upright black hairs. 

 The elytra are of a deep violaceous or indigo-blue, uniformly 

 rugulose ; the rugosities are tuberculous. They are widest a little 

 before their apices, the apex broadly rounded. In addition to 

 the black erect hairs there is a white, shining, pi'uinose 

 pubescence, arranged in fasciae (but not very evidently so). 



The legs and underside are wholly jet-black. 



The male has the head unevenly impressed between the eyes, 

 the antennae more acutely serrate, and of course the front tarsi 

 four-jointed. The elytra cover the abdomen in air of the four 

 specimens before me ; in the female the segments of the abdomen 

 when distended appear narrowly margined with red.

A genus recalling by the curious sexual characters of the 

 antennae in the male the genera Laius from Australia and Collops 

 from the New World, and by its excavated and coi-nuted head 

 in the male the genus Hedybius, with which it might have 

 been associated ; but I think although the enlarged fifth and 

 sixth joints of the antennae are only a sexual character, it is one 

 so similai- to what is found in Laius and Collops that it will be 

 well to keep insects of this family possessing it in a separate
