4 84 Mr. E. Bergiotli on 



colour-inaikin<>;s of tlie scutellum none of the numerous 

 varieties ot' artensis seems to be similar to the single known 

 specimen of the Borneaii species. 



Tiie species of Coleoiichus principally inhabit the islands 

 of the Paciric Ocean. One species is known from Sumatra, 

 but none had previously been found in any of the other great 

 iSuiida islands. 



Fam. Pentatomidae. 



Subfam. Abmin^. 



Schouteden has divided Canthecona, Am. S., into two 

 genera, separating the Asiatic species as a distinct genus, 

 Cuntheconidea. The latter genus he divides into two sections, 

 A and B, corresponding to Stal's division ai and aaa of 

 Canthecona. Tliese sections differ much more inte)' se than 

 the section B of Cantheconidea differs from Canthecona, and 

 must in my opinion be regarded as distinct genera with the 

 following characters : — 



The eides of the tQetasternum strongfly cari- 



nately raised above the level of the coxjc, 



freely produced forward and backward 



between the coxai. Tibiaj cylindrical, only 



toward the apex flattened or slightly sulcate. 



The males with no sericeous patches on the 



venter ; apical niarfrin of sixth male ventral 



segment br()adly bisinuate. (Type: C.Javana, 



Dall.) Cantheconidea, Schout. 



The sides of the metasternum a little raised, but 



not produced forward and backward. Tibice 



conspicuously sulcate down their whole 



length. The males with a large sericeous 



(stridulatory ?) patch on each side of the 



venter extended through the fourth and fifth 



segments ; apical margin of sixth male ventral 



segment broadly unisinuate. (Type: C'.fur- 



cillata, Wolti") Eocanthecona, gen. no v. 



Asopus chri/sopterus, H. Sch., from the island of Guam, 

 has remained unknown to later authors, but has in all 

 catalogues been placed in Canthecona, and later in Canthe- 

 conidea ; yet from the description and figures, and from the 

 fact that Herrich-Schaffer placed it in a division chaiacterized 

 by '' Vorderschenkel ohne Dorn," it is clear that it has 

 nothing to do with this group of genera. There can be 

 little doubt that it belongs to an undescribeJ genus.
