the head shortened behind the eyes, and some other 

 minor points, it considerably approaches the genus 

 Pliymafodes, * and must, I think, be considered as a link 

 connecting the two sub-families. The antennse in this 

 species have the second joint very strongly transverse; 

 the terminal robust, ovoid, and not, as in Phyniatodes, 

 elongate and sub-cylindrical ; the prothorax, moreover, 

 and the form of the labium and the maxillary palpi are 

 different from that genus, and more closely resemble the 

 corresponding parts in Goniadera. 



The Goniadera cariosa (Dej. Cat.), judging from an 

 example so named in the Lafertean collection, has the 

 penultimate joint of the tarsi as strongly expanded be- 

 neath the claw joint as in the genera Ancedus and Ly- 

 props, and should form the type of a distinct genus t 

 of the sub-family Heterotar since ; the whole group, how- 

 ever, yet requires a very careful study on a large 

 number of species, when, probably, it will be found 

 necessary to erect the species just described into a dis- 

 tinct genus. 



Another new genus, or sub-genus, will be an insect re- 

 cently received from Mr. Hauxwell from Pebas, in Peru : 

 it is very closely allied to Phymatodes (having quite 

 a similar habit) , but is at once separable by the re- 

 markable form of the antennge, which are shorter and 

 stouter, the joints becoming gradually shorter and 

 wider ; 6-10 are strongly transverse ; 11 large (but shorter 

 than in Phymatodes) , and strongly bent or arched ; 3, 4, 

 5 are flattened on the under side, and 6-10 are not only 

 thus flattened, but are concave, or very broadly channelled 

 along their length, beneath. Only a single example, a $ , 

 of this insect has been received (I have seen another 



* lu which, also, the loeunltimate joiut of the tarsi only approaches 

 the sub-hilobed form, and cannot be considered as at all expanded beneath 

 the claw joint. Mr. Pascoe has proposed I(Jouru. Linn. Soc, Zool. ix. 

 142, u.) the name Phymatestes, in lieu of Phymatodes, the latter having 

 been pre-occupied. 



f Keadily distinguishable from Phymatodes (irrespective of its much 

 smaller size and different habit) by the character already mentioned, and 

 by its remarkably slender labial palpi ; the second joint of the maxillary 

 elongate, slender, and curved at the base ; and by its spurred tibire : — from 

 Phobelius by the latter character, and by its simple hind thighs : — from 

 Ana'dus by the base of its prothorax being squarely truncate, with the angles 

 simple, and by its jet-black, shining, deeply creuate-striate elytra : — and 

 from Lyprops (OUgorus, Dej. Cat.) by this last character, as well as by its 

 transverse prothorax, and short broad elytra. I propose to name the 

 genus Mmymone, and purpose soon to describe it in detail.
