Nigra, nitida ; capite prothoraceque parcius et sat profunde punctatis ; elytris singulis striis septem, leviter impressis, crebre minute punctatis, fasciis duabus interruptis, una basali utrinque dentata, altera ante apicem, late rufis. Long. 7-8 millim. Hab. Andaman Islands (coll. Gorham). This species at first sight so very closely resembles E. senegalensis, Lap., = £'. interrupta, Lac, that it will suffice to point out the distinction. The head and thorax are more shining and more sparsely and more deeply punctured. The elytra have seven distinct although very fine punctured stria?; in E. senegalensis stria? are not visible, but the elytra are punctured all over, and are subsulcate only at the apex. The basal fascia does not run obliquely up to the shoulder, where in E. senegalensis it is widest, but runs straight across, emitting a single tooth towards the base. It is more convex than the African species, and is more brightly coloured. A third species even more closely allied to E. senegalensis, if not the same, occurs in India. 17. EPISCAPHA OCTOPUSTULATA. (Plate XVIII. fig. 4.) Nigra, nitida, supra valde convexa; capite sat fortiter crebre punctato ; prothorace parcius et subtilius punctato, ad angulos anticos macula rotundata aurantiaca ; elytris sublavibus, maculis duabus subhumeralibus (inferiore maj ore) alteraque magna transversa ante apicem aurantiacis. Long. 15 millim. Hab. Philippine Isles, E . Mindanao (Semper). This is unlike any other Episcapha known to me, in having the thorax spotted; and its convex look would have led to m e to make a new genus for it, but I fail to find any valid characters by which to separate it. The prosternum is almost angularly cut out at its posterior margin, but it is almost equally so in E. semperi; it is compressed in front into a blunt point, and is roughly punctured, but the epipleura? are smooth. The form of the mesosternum is somewhat peculiar : it is compressed in front so as to form a sub-triangular table, with its apex in front, and rounded, fitting the excavation of the prosternum. Metasternum obsoletely punctate. 18. EPISCAPHA PICIVENTRIS. Nigra, subnitida ; capite prothoraceque subtiliter alutaceis, crebre et minute punctatis; elytris obsolete striato-punctatis, fascia humerali subobliqua, sutura interrupta, utrinque dentata, lunulaque subapicali valde arcuata fiavis ; abdomine rufo-piceo. Long. 10-11 millim. Hab. Old Calabar (coll. Murray). This species is a little larger than any E. senegalensis I have seen, and is at once separable from that species by the delicate punctured striae, as well as the narrow fascia and by the hinder one being arcuate. It is more nearly allied to the species standing in |
