[Read March 4tli, 1885.] 



The following new species of LancjuniclcB are from 

 Guinea, with the exception of one fine species of Calli- 

 lanquria from the Philippine Islands ; they are more 

 particularly interesting, as comparatively few species 

 have hitherto heen described from Africa. One new 

 genus, which appears to be distinct, has been formed, 

 and it is probable that two or three of the other species 

 have a claim to generic value : the more, however, that 

 the Languriidce are studied the more evident it becomes 

 that an entire revision of the family is necessary, and 

 that the genus Languria, at all events, is composed of a 

 number of heterogeneous groups that will ultimately 

 have to be separated. There is one character that 

 hitherto has been much neglected, but which seems 

 likely to prove very useful, and that is the formation of 

 the parts of the head and the position of the antennae. 

 In the LanguriicUe the antennae are inserted in sockets, 

 which vary very much in size, shape, and depth ; these 

 stretch obliquely from the eyes to the clypeus, and are 

 therefore larger or smaller, accordingly as the eye 

 approaches the clypeus or is removed farther from it. 

 In some genera (e. g., Fatiia, CallUanguria, Langurites, 

 and Goniolanguria), there is a clear corneous space 

 between the eye and the commencement of the socket ; 

 in others, as in Teretilanguria , there is no intervening 

 space, and the eye appears to open straight upon the 

 socket. If we examine the various species of the genus 

 Lanquria we shall find that many of them have a clear 

 space between the eye and the antennal socket (as, for 

 instance, L. Iceta, L. discoidca, L. atriceps, and the 

 species, as a rule, that have the prothorax red), whereas 

 other species (e. g., L. ingens, L. ge7iicnlata, L. Leivisii, 

 &c.), have the eye opening immediately, or almost 

 immediately, on "the socket, as in Teretilanguria, to
