//. parallelogrammica, depressa, obscure fusca cinereo-fulva varie- 
gata ; elytris medio fascia undulata, obscura, cinereo-fulva. Long. 
6^8 lin. S $ . 
Head dull brown; forehead broad, sparingly punctured; an- 
tenniferous tubercles in the male produced on their inner side 
into a stout pointed tooth. Antennae in the male nearly twice 
the length of the body, with the apical joint greatly elongated ; 
in the female about the length of the body, apical joint shorter 
than the preceding ; colour dull brown or blackish. Thorax 
uneven above, sides with a short pointed tubercle ; dull brown, 
speckled with black. Elytra slightly narrowed from base to 
apex, shoulders slightly prominent and surmounted by an ob- 
tuse shining tubercle; surface even, thickly but finely punc- 
tured, dull brown, covered with dingy tawny confluent spots, 
and crossed beyond the middle by a zigzag fascia of a little 
paler hue. Body beneath and legs blackish or dull brown. 
Common on branches of dead trees at Ega. There are two 
closely allied species in collections from the interior of French 
Guiana*. 
* Hesycha jaspidea, n. sp. H. Nyphonoidei simillima, robustior, maris

fusco-nigra, maculis sordide fulvis sparsis quarum tribus majoribus 
medianis in fasciam abbreviatam conjunctis. Corpus subtus fulvo to- 
mentosum. Antennae valde elongatse, articulis basi griseis. Long. 
8 lin. <? . Hab. In Cayenna interiore (Dom. Bar). 
Hesycha liturata, n. sp. Minor, brunnea, elytris litura tenui obliqua 
albicante. Caput fuscura, fronte punctata, tuberculis antenniferis

brunneo tomentosa. Long. 5-6 lin. S 2 • Hab. In Cayenna (Dora. 
Bar). 
The following species belongs also to this genus, from its linear sub- 
depressed form and the somewhat wide separation of the antennae at their 
bases : — 
Hesycha xylina, n. sp. Elongata, sordide brunnea ; elytris rugoso-punc- 
tatis, fusco et griseo strigatis, humeris subuncinatis. Caput fuscum, 
fronte grosse sparsim punctata, tuberculis antenniferis intus dente va- 
lido curvato armatis ( S )• Antennae valde elongatae, brunneae, apice 
pallidae, articulis (a tertio) basi testaceis, articulo 12^0 acuto, curvato. 
Thorax supra inaequalis, inermis, brunneus. Elytra valde elongata.
