i. Antennae 11-jointed MYCETiEiNiE (Leiestin^e). 



ii. Antennae 4-jointed Trochoidein;e. 



II. Tarsi crypto-tetramerous, apparently 3-jointed, 

 the third joint being very small and concealed 

 between the lobes of the bilobed second joint, 

 i. Ligula oblong, with its free margin rounded. . ENDOMYCHiNiE. 



ii. Ligula at least as broad as long, with its free 



margin truncate or emarginate.

pressed, sub-foliaceous. 



A. Labial palpi with the last joint transverse. Eumorphinje. 



B. Labial palpi with the last joint quadrate . CoRtNOMALiNiE. 



2. Antennae with the club subcylindrical or only 



slightly compressed. 



A. Antennae with joints 9-10 pointed and 



prolonged internally Epipocin^e. 



B. Antennae with joints 9-10 not prolonged 



internally.

b. Form short-oval or round Stenotarsinje. 



Mr. Grorham (Biologia Centr.-Ainer. vii, p. 115) places the 

 Endomychid^e next to the Erotylid.e, and says that the passage 

 from the latter to the former through Homoeotelus seems natural 

 enough, and some species of Brachysphenus, such as B. festivus, 

 have quite the facies of. the Endomychid.e. "The family," he 

 says, " is somewhat more specialised, but, on the other hand, its 

 representatives are far inferior in number, both in genera and 

 species, to the Erotylid.e. The Palasarctic and Nearctic zones 

 and low Southern latitudes possess few and feeble forms; as a 

 group, they are a tropical development of a peculiar type that has 

 never been dominant, dependent on special circumstances for their 

 existence, and therefore rare in nature." 



Family 47. COCCINELLIME. 



Form usually round, rarely oblong-oval, convex, head deeply sunk 

 in thorax ; antennce inserted at the inner front margin of the eyes, 

 eleven-jointed {rarely eight- to ten-jointed), with a variable, usually 

 three-jointed, club; anterior coxal cavities open or closed behind; 

 elytra ivith very distinct epipleuroe ; anterior and posterior coxa? 

 transverse and separated ; legs short, usually strongly retractile, the 

 posterior pair often fitting into more or less hollowed shallow plates 

 (plaques abdominales)* ; tarsi pseudo-trimerous, the third joint being 

 very minute and concealed (except in Lithophilus, in which it is free) ; 



* These are of great use in the separation of genera, as they vary much in 

 size and shape ; they are present to a less extent on the metasternum also.
