the Australian Piestid genera which have their abdomen unmar- 

 gined by its tarsi consisting of only three joints. 

 G. sculptum, sp. nov. Obscure ferrugineum ; vix subnitidum • 

 subglabrum ; vix perspicue punctulatum ; capite 

 longitudinaliter obtuse 3 — carinato : antennis brevibus 

 robustis, articulis basalibus 7 moniliformibus 8° — 10^ 

 trans versis 11° breviter subconico, articulo basali quam 

 sequentes (clavse exceptis) paullo majori ; prothorace trans- 

 versim subquadrato, retrorsum leviter angustato, supra 

 valde inaequali (interrupte intequaliter obtuse longitudinaliter 

 multicarinato), in disco planato, quam caput paullo latiori 

 vix longiori, angulis posticis valde acutis, lateribus vix 

 arcuatis ; elytris quam prothorax sat brevioribus, carinis 

 discoidalibus eirciter 4 obtusis longitudinalibus ornatis 

 Long., 1 1.; lat., \ 1. 

 The only previously-described Glyptoma with which I am able 

 to compare this species is the Hawaiian G. Blackburni, Shp. It 

 does not seem to differ from that insect by any character likely 

 to be generic ; as a species, however, it differs widely by inter 

 alia its very much smaller size and very much shorter elytra, as 

 well as by its evidently less opaque surface.

 G. sordidum, sp. nov. Prrecedenti {G. sculpto) affinis ; capite 

 subobsolete 3 — carinato ; oculis magis prominulis ; antennis 

 minus robustis ; pronoto in disco planato parum inaequali, 

 utrinque versus latera subtiliter 2 — carinato, angulis posticis 

 minus acutis ; elytris quam prothorax eirciter tertia parte- 

 longioribus ; cetera ut G. sculptum. Long., f 1. 

 This species can be at once distinguished from the preceding 

 by its very much longer elytra, and notably smaller size. It also 

 differs by the much less uneven surface of its head and prothorax 

 and by its evidently convex eyes (in G. scidptum the eyes 

 scarcely stand out distinctly from the general outline). The 

 sculpture of the head consists of the disc being longitudinally and 

 very widely and feebly convex, with a much narrower and some- 

 what more evident longitudinal convexity on either side near the 

 eye. The pronotum is on the disc, almost even, but flattened, 

 with a vague depression in the middle of the flattened portion 

 and a feeble arched transverse sulcus near the base (in scidptum 

 the disc is occupied by strong obtuse carinas confusedly inter- 

 rupted so as to seem like seriate tubercles from a certain point of 

 view, and a strong arched transverse sulcus near the base) ; the 

 lateral part on either side bears two fine raised lines (in sculptum 

 these are quite strong costre). The sculpture of the elytra is 

 much the same in the two species.
