of abdomen black ; apices of coxa?, apices of femora, extreme bases of tibice, rostrum near base, central 

 portions of sternum, and the abdomen, ochraccous. 



Tegmina and wings blackish, the venation brownish-ochraceous ; tegmina with the base narrowly 

 brownish-ochraceous and crossed by a narrow creamy fascia, commencing beneath and near the apex of 

 radial area and terminating on posterior margin beneath the lower apical area. 



Var. a. — AVings with some obscure pale submarginal rays as in the specimen figured (Tab. II., fig. 1). 



Var. h. — Wings with the venation black and concolorous. 



Var. c. — Tegmina with the transverse creamy fascia much widened. 



Var. d. — Mesonotum with two central ochraccous spots (Tab. II., fig. 2).

I possess a specimen labelled " China," but do not care to attach much importance to 

 that habitat without further corroboration. T. fasciata, according to present knowledge, is a 

 purely insular form, and is replaced on the mainland by the following race ? or species ? 

 T. mclanoptcra. 



In some specimens the posterior margin of the pronotum is green, and not ochraceous, 

 but this colour difference does not constitute a distinct variety, as it is observed co-existent 

 with the other aberrations already described under vars. a, b, c.

Allied to T. fasciata, but tegmina and wings darker in hue, the transverse creamy fascia to tegmina 

 much less oblique ; pronotum without the small ochraceous spots at anterior margin, and the abdomen 

 beneath more or less blackened, but prominently so near base and apex. 



Var. a. — Legs black, with the apices of the femora ochraceous. 



Var. b. — Legs uniformly black. 



Var. c. — Tosena albata. (Tab. II., fig. 4, a, b.)

Tegmina with five longitudinal greyish fasciae, one occupying radial area, and the others divided by ulnar 

 veins, two of which amalgamate with the transverse fascia, and five irregular greyish fasciae situate in the 

 apical areas. Wings with nine greyish ray-like fasciae situate on outer margin, the one at anal area 

 largest; two-thirds of the outer margin narrowly edged with greyish. Apices of the femora not ochraceous.

This species ? or race ? seems to be only separable from T. fasciata by colour differences, 

 the usual structural characters used in differentiation, such as the shape of the opercula, &c., 

 being apparently identical in both T. fasciata and T. vtclatwptcra. The internal structure of the
