absence of perfect wings in the male and the usual row of raised 

 vittje on the hindmargin of the abdominal segments, but this is 

 not considered sufficient for the establishment of a new genus. 



Epilampra medivextris, Saussure (Rev. ZooL, XYI., 321, 

 1864; Brit. Mus, Cat., 76). 



Habitat. — Tasmania. 



Epilampra pectinata, Saussure (Mel. Orth., II., fasc, 1870). 

 Habitat. — Australia. 



Epilampra irrorata, Thunberg (Nov. spec, 4, 76 ; Fabr. Ent. 

 Syst., II., 8; Brit. Mus. Cat., 231). 



Habitat. — Australia. 



If Walker's references be correct, the name represents 

 Deropeltis erythrocephala, Fabr., Blatta Capensis, Thunberg. 



The above specific name is not cited by Brunner, although the 

 works mentioned by Walker are quoted, and the pages next to 

 his. 



Opisthoplatia, Brunner (Syst., 198, fig. 22). 



" Body oblong. Pronotum with hindmargin straight, or 

 broadly emarginate. Elytra and wings abbreviated or scale-like. 

 Abdomen very broad behind ; of the male flat, of the female 

 rather convex ; hindmargin of all segments rugose, with raised 

 streaks. Cerci very small. Last segment of female triangular, 

 broadly sinuate." 



The presence of both elytra and wings is the chief distinctive 

 character. Of the four species kno^^'n, two occur chiefly in Asia 

 and the Malayan Islands, the others in South America. 



Opisthoplatia orientalis, Burmeister. 



Handbk. II., 482; Br., Syst., 199. 



" Red, dorsum black, margin brownish-red. Pronotum with 

 the anterior margin testaceous. Elytra and wings lobiform, 

 acuminate, equal in length, blackish, foremargin red. 



Male. Female. 



Length of body ... ... 24 mm. 27-33 mm. 



Length of elytra and wings 4*5 " b'Q " 



Length of pronotum ... 7*5 " 8-9 " 



Width of pronotum ... 12 " 14-15 



Habitat. — Australia (Brit. JIus. Cat., 152); India, China, 

 Brazil (^yst.)." The home of this species is most likely North 

 Australia, or Queensland; 0. australis, Burm., inhabits Brazil, 

 not Australia.
