Syn. Blatta Ægyptiaca? Linn. Syst. Nat. 1. 2. 687. 2. Gronov. Zooph. 637. t. 15. f. 3. Ahrens Fauna Ins. Eur. f. 1. tab. 13. Fabr. Ent. Syst. 2. p. 6.

Habitat: Jamaica (Drury). Egypt (Linnæus).

Head and antennæ dark brown. Thorax dark brown, and surrounded, except on the hinder side, with a cream-coloured margin. Wings and wing-cases brown and thin, the latter having a cream-coloured streak along the anterior margin, about a quarter of an inch long. Abdomen and legs brown. The thighs and tibiæ being furnished with many spines.

I have added a mark of doubt to the specific denomination of this insect on account of the different habitats given by Drury and Linnæus, although it agrees with the description of Blatta Ægyptiaca given by the latter author.
