Q^() [September, 



with lapponicus, L. I have examined Stephens' specimen which is in 

 the British Museum, and it is not an Ectobia, but a Phyllodromia, and 

 I shouTd think it probably a stray exotic species, as P. germanica, L., 

 is the only European representative of the genus. 



ii.— PHYLLODEOMIA, Serville. 

 Distinguished from Ectobia by the absence of the dilated apical 

 area and the form of the supra-anal plate ; also in this genus the 

 ulnar vein, instead of arising from the radial vein, comes separately 

 from the base, and the radial vein branches only anteriorly.

 Phyllodromia germanica, Serv,, Orth., p. 107 ; Brunner, Prod, der Eur. 



Orth., p. 46, fig. 9. 

 Head ferruginous, paler behind the vertex and below the insertion of the 

 antennae. Antennae testaceous. Pronotum testaceous, with two blackish-brown 

 longitudinal bands, which do not quite reach either the anterior or posterior margin, 

 and are prolonged backward over the mesonotum. Elytra unicolorous, lanceolate. 

 Wings smoky towards the costa. Legs testaceous. Abdomen testaceous, with some 

 fuscous markings above, darker below. Cerci long. Length, 14 — 15 mm. 



Egg capsule oblong, with more strongly marked angles than in 

 Periplaneta, and with the opening at the side, not dorsal as in Peri- 

 planeta. 



This species is found in woods in Central Europe, and has taken 

 up its abode in many houses. In England I have found it in many 

 London restaurants, and in some of the houses in the Zoological 

 Society's Gardens. Wherever it is found it is in large numbers. 



iii. — PEKIPLANETA, Burmeister (fig. 2). 

 This genus, which includes the common house cockroach, is at 

 once distinguished by the large size of the species. The subgenital 

 lamina is divided into lateral lobes, and these embrace the egg capsule, 

 which has its long diameter perpendicular instead of transverse, as in 

 Phyllodromia. The branches of the radial vein are mostly branched 

 (fig. 2), and the two ulnar veins arise separately from the base.

mentary 1. orient alis, Linne. 



2 (1) Elytra and wings in both sexes fully developed, longer than the abdomen.
