I'-'-udotrimera. But :..- _ -rally placed in the Clavicorn 



ar Endoniychidae, rhoeff has recently made con- 



morphological stu: the male genital organs of 



i, and as the result, he concludes that Coccinellidae 

 radically from all other Coleoptera as regards these 

 - _ ictures, and he therefore treats them as a distinct series or 

 sub-order, termed Siphonophora. The genus Lithophilus has been 

 red doubtfully a member of Coccinellidae, as the tarsi 

 -sess only in a slight degree the shape characteristic of the 

 .ilv : Verhoeff finds that they are truly Coccinellidae, forming 

 a distinct division, Lithophilini: and our little species of Coccidula, 

 which have somewhat the same appearance as Lithophilini, he 

 its as another separate group, Coceidulini.

' tico joints broad, the terminal joint elongate ; at the base of 



terminal joint there is, however, a, very small joint, so that the 



<i are pseudotetramerous ; antennae rather large, with a large 



' ; labium not at all retracted behind the mentum; front and 



hlle coxae globose ; abdomen with five movable ventral segments, 



and, a sixth more or less visible at the tip. 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, "\Ve 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.
