Pseudotrimera. But they are -run-ally plaerd in tin- ( 'lavicorn 

 series, near Endomychidae. Yrrhoeff has recently made con- 

 siderable morphological studies on the male genital organs of 

 Coleoptera, and as the result, he concludes that Coccinellidae 

 differ radically from all other Coleoptera as regards -these 

 structures, and he therefore treats them as a distinct series or 

 sub-order, termed Siphonophora. The genus Litlm^h il as has been 

 considered doubtfully a member of Coccinellidae, as the tarsi 

 possess only in a slight degree the shape characteristic of the 

 family: Verhoe ft' finds that they are truly Coccinellidae, forming 

 a distinct division, Lithophilini; and our little species of Cucdd idn, 

 which have somewhat the same appearance as Lithophilini, he 

 treats as another separate group, Coccidulini. 



Fam. 39. Endomychidae. 1 - -Tarn apparently three-jointed, the 

 first two joints broad, the term I mil jnint elongate; at the base of 

 the terminal joint there is, ho'trever, a very small joint, so thf /// 

 tarsi are pseudotetramerous ;' antennae rat/nr large, with a large 

 club; I,//,/'//,/, nut at all retracted behind the mentum ; front and 

 middle coxae globose ; abdomen witlt, five movable ventral segments, 

 mid a si i'tli more or less visible at the tiji. This family includes 

 a considerable diversity of elegant Insects that frequent fungoid 

 growths on wood. It comprises at present fully 500 species, but 

 nearly the whole of them are exotic, and inhabit the tropical 

 forests. "We have only two British species, both of which are 

 now rarities, but apparently were much commoner at the 

 beginning of the century. The larvae are 

 broader than is usual in Coleoptera ; very 

 few, however, are known.

group is an altogether artificial one ; but we think, with Duval, 

 it makes matters simpler to separate them. There are only
