 Mel. Orth., in Mem. Soc. Phys., Geneve. 

 Habitat. — Australia. 



Eleutheroda, Bynmner (Syst., 264, fig. 29). 



" Silky pilose. Head laroe. Pronotum semiorbicular in front, 

 truncate behind. Elytra flat, almost rectangular, scarcely slant- 

 ing, not exceeding the abdomen. Wings twice as long as the 

 elytra, wholly folded back in the middle. Legs slender. Abdo- 

 men oblong, convex beneath. Supra-anal lamina of male trans- 

 verse ] of female rounded. Cerci small, base very broad, four- 

 jointed. Subgenital lamina of male small ; styles short. 



The insects resemble Coleoptera considerably in appearance, and 

 much more so than any other of the Blattari^e, except Cassidiodes, 

 from the Philippine Islands, but of different type ; the former 

 apparently mimicking certain Tenebrionido?, the latter resembling 

 our black Paropsinge. 



Eleutheroda galerucoides, Walkei-. 

 • Diploptera, Brit. Mus. Cat., 57. 

 "Tawny, flat, elliptical, shining, very finely punctured, 

 minutely setulose. Head largely but distantly punctured. 

 Antennae submoniliform, shorter than body, base black. 

 Pronotum transversely subelliptical, sides much rounded, semi- 

 hyaline, hindmargin straight, disk with two interrupted, much 

 abbreviated, blackish bands. Elytra coriaceous. Wings cinereous, 

 hyaline. Legs moderately long. Abdomen piceous, slightly

Panchlorid.e {Br., Syst., 266). 



Head rather thick, partly or wholly covered by pronotum. 

 Pronotum mostly smooth, angular or truncate behind, flat or 

 hooded. Elytra perfectly explicate (except Oniscosoma), rounded, 

 without apical area, anal vein impressed, axillary veins very 

 close. Wings rounded in front, apical area not distinct, fan-like 

 explicate, anal area fan-like, ulnar vein pectinate. Femora 

 unarmed; tarsi wdth arolia. Abdomen depressed, angles of

 soma. 



Most species of the six small or moderately-sized genera of this 

 family are extra-Australian, and widely distributed. The chief 

 distinctions are the quadrate, incised or entire lamina of the
