the absence of raised interstices separate it from lycoides, 

 the eyes are even less prominent than in that species. I 

 do not think it will prove to be the alternate sex of either.

This species bears a striking resemblance to Platynop- 

 tera Goryi, the palpi, however, are not hatchet-shaped. 

 The thorax has its sides not sinuate, as in that species, but 

 nearly straight, only subtuberculate in the middle, wider 

 at the base than in front, the elytra are widened nearly as 

 in P. Goryi, the punctures deeper, the fascia is inter- 

 rupted by the suture. The reflexed edge of the elytra is 

 yellow as far as the fascia, and there is an indistinct short 

 line of the same colour between the humeral vitta and the 

 suture, which also has a few yellowish hairs.

Ichnea Batesiana, n. sp. 



Nigra, subopaca, capite subtus, maculaque parva 

 occipitali, thorace linea mediana, scutello, elytris margine 

 humerali, fasciaque irregulari in medio, a sutura inter- 

 rupta, femorumque basi flavis.

A remarkable species, in form resembling a Platynop- 

 tera, the palpi are, however, not hatchet-shaped ; it also 

 somewhat resembles certain Pelonia, but is verj distinct, 

 by the reduced, and confused third to eighth joints of the 

 antenna, as well as in the form of the palpi. 



Antennae half the length of the body. Head and thorax 

 with erect brown seta, the latter with the sides evenly 

 rounded, formed much as in P. pilosum. Scutellum 

 yellow, elongate triangular. Elytra rather wider than 

 thorax at the base, widening to about three times that 

 width before the apex, which is suddenly rounded, obso- 

 letely punctured, subcoriaceous of a dull black, the margin 

 at the humerus and central fascia yellow, the latter not
