16. Episcapha difficilis. 



Nigra, nitida ; capite prothoraceque parcius et sat profunde punc- 

 iatis ; elytris singulis striis septem, leviter impressis, crebre 

 minute jiunctatis, fasciis duabus interruptis, una basali utrinque 

 dentata, altera ante apicem, Icete rufis. 



Long. 7-8 millim. 



Hab. Andaman Islands {coll. Gorham). 



This species at first sight so very closely resembles E. senegalensis. 

 Lap., = E. 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 striae ; in E. senegalensis striae 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 



punctata ; prothorace parcius et subtilius punctata, ad angulos 

 anticos macula rotundata aurantiaca ; elytris sublcevibus, niaculis 

 duabus subhumeralibus (inferiore majore) alteraque magna trans- 

 versa ante apicem aurantiacis. 

 Long. 1.5 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 me to make 

 a new genus for it, but I fail to find any vahd characters l)y which 

 to separate it. The presternum 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 epipleurse 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 apes 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 

 subupicali valde arcuata flavis ; 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
