222 MR. A. MURRAY'S MONOGRAPH OF THE FAMILY OF NITIDULARLE. 
separate dorsal part of the segment were removed there would still remain an abdominal 
ring (fig. 14). I propose to call this hem or turned-over part of the 
segment the fimbria. 
Legs.—PFemora. These are almost always more or less flattened; (Æ< 
in some of the species of Camptodes, Amphicrossus, and ZEthina, very 
much so. Where the flattening is not very great, there is a slight Pat e 
depression on the posterior edge of the femur in which the base of the 
tibia is received. When the legs are very much compressed the inner Fig. 15. 
and posterior side of the femur is thinned to half its thickness, so that 
the flat tibia folds in upon the flat femur like the blade of a paper- 
cutting knife. Fig. 15, letter b, shows this arrangement. In such 
cases the side of the tibia and that of the thin portion of the femur 
are highly polished, although the rest of the leg may be punctate or 
pubescent. te 
Tibia. Sometimes very broad and thin, at others not flattened. pina leg of Camptodes 
The very broad tibie are confined to the Strongyline. In Meli- inen: 
gethes the serrations of the anterior tibiæ are found to afford useful specific characters. 
In some genera ( Brachypeplus for example) there is a small groove on the outer side of 
the apex, for the reception of the tarsi (see Plate XX XIV. fig. 10, c). 
Tarsi. Pentamerous, but the fourth article is very small. The three first are usually 
broad, and furnished with long brushes of hairs beneath. The small fourth article 
(fig. 15, a) is one of the best characters for distinguishing the family. It is absent in 
no species belonging to it, if we remove Cybocephalus from it, which, I think, ought to 
be done.

LARVA AND METAMORPHOSES. 
The remark made by M. Candéze and M. Chapuis upon the larve of this family, in 
their modestly styled ** Catalogue des Larves des Coléoptéres connues jusqu'à ce jour, avec 
la description de plusieurs espèces nouvelles," may at this day be repeated with little 
alteration—** There are few families so considerable as this, of the earlier stages of which 
so little is known: not more than five or six of these larvee have been described." 
Anything further that is known in relation to them proceeds from M. Edouard Perris, in 
his * Insectes du Pin maritime" (Ann. Soc. Ent. France, 1853), and from M. Candeze him- 
self, who in his * Histoire des Métamorphoses de quelques Coléoptéres exotiques ' (1861) 
has added the descriptions of two or three to the number. But still the number known 
is even more limited than those mentioned by these entomologists. The five which had 
. been described previous to the publication of their catalogue were 0 obsoleta, 
Soronia grisea, Pocadius ferrugineus, Ips 4-pustulata, and Rhizophagus depressus. But 
of these the descriptions of Epurea obsoleta and Ips A-pustulata were so little detailed as 
to be of no use, and a doubt has been suggested by Erichson whether Bouché, who 
describes Pocadius ferrugineus, had not confounded it with a Lycoperdina ; which 1s 
not an improbable supposition from his description, and from the fact that both feed 
on the Lycoperdon Bovista. Rhizophagus Y do not include in my subject. The larva of
