COCCINELLID.E. 



Anterior coxae transverse, cavities generally closed. 



Posterior coxa; distant, not reaching the margin, sometimes sulcate. 



Ventral segments 5-6 (7 in Hyperaspis <$). 



Tarsi 4-jointed, 2d bilobed, 3d very minute, claws generally dentate. 



The structure of the tarsi has generally caused these insects to be 

 placed at the end of the order, but they evidently belong in the Clam- 

 corn series, from all other families of which they differ by their tarsi, 

 combined with securiform palpi, generally dentate claws and usually 

 closed cavities. The only other family with similar tarsi is the Endomy- 

 chidw, which has small globose anterior coxae, with open cavities, and 

 simple claws. It is, however, to be noticed that the elongate aberrant 

 Coccidula has sub-globose anterior coxa?. The coxae are often sulcate as 

 in Cistelidce. 



Ctstelid.e. 



Anterior coxae transverse, cavities open. 



Posterior coxae sub-contiguous, reaching the margin. 



Ventral segments 5, 1-3 sub-connate. 



Tarsi 5-jointed, often lobed beneath. 



Antennae gradually clavate, legs retractile, hind coxae sulcate. 



This family is very distinct by its facies. Chelonarium may form a 

 separate family, the antennae are entirely filiform. I have reverted here, 

 as elsewhere, to Geoffrony's name for the typical genus (1702) ; the name 

 Byrrlius belongs to the Anobium, Fabr., and the Byrrhus of Linnaeus is 

 Anthrenus, Geoff. By means of Liminichus this family is closely allied 

 to Georysxus and Elmis. 



Georyssid^e. 



Anterior coxae compressed, trochanters large, covering the prosternum, 

 cavities open. 



Posterior coxae distant. 



Ventral segments 5, 1st very large, 1-2 connate. 



Tarsi 4-jointed, antennae 9-jointed. 



Allied to Cistelidce (Byrrhidce) by the general habit ; distinct. 



PSEPHENID^E. 



Anterior coxae globular, cavities open, prolonged externally, trochanter 

 very large. 



Posterior coxae dilated into a plate, contiguous. 



Ventral segments 6-7, 1-2 connate. 



Tarsi 5-jointed. 



Maxillary palpi very long, securiform, antennae long, filiform. This 

 insect is most singular and anomalous ; notwithstanding the evident 

 affinity to Parnidm it differs remarkably from it by the elongate palpi and 

 6 ventral segments. The 7th ventral segment is visible only in the -j, . 

 It is in many respects closely allied to Belodes in the Serricomes. This 

 family is the commencement of a small group of closely allied families, 

 differing in the details of the coxa?, but agreeing remarkably in the parts 

 of the mouth.
