AN<EME. 53 



Lateral margins of prothorax in general feebly developed, some- 

 times (Anceme) consisting merely of a fine carina that extends on 

 each side from the basal margin to the outer angle of the coxal 

 cavity. Wing-venation of the usual Prionine type. 



This group, as here defined, is a provisional one and corre- 

 sponds in part only to Lacordaire's group of the same name. For 

 two of the genera included by him, I have formed a separate 

 group the Philini. Two other genera Cyrtoiiops and Crinosoma, 

 which were imperfectly known to him and doubtfully placed in 

 the group will also have to be excluded; one belongs to the 

 Disteniince and the other to the Cerambycince. Anceme, the only 

 genus of the group included in our fauna, is represented by two 

 species in Africa and one, recently discovered by Mr. H. L. 

 Andrewes, in the Nilgiri Hills, Southern India. M. Lameere 

 (Faune Ent. de 1'Afrique Trop., Longicornes, p. 47, 1903) has 

 associated this genus with Plectogaster, Waterh., placing both 

 in the group Anacolini. The Monodesmini have, it is true, 

 a fairly close relationship with the Anacolini, as they have also 

 with the ^Egosomini ; they ought therefore perhaps to be merged 

 in one or other of these two groups. With Plectogaster, however, 

 the case is different. Notwithstanding the fact that this genus 

 has been placed in the Prionince not only by M. Lameere but also 

 by two other experienced entomologists, I am decidedly of opinion 

 that it ought not to be so placed, but was rightly referred by 

 its author to the Cerambycince, chiefly for these reasons : (1) the 

 prothorax has no true lateral margin, (2) the front coxae though 

 transverse are not more so than in many Cerambycince, (3) the 

 inner lobe of the maxillae is quite fully developed, (4) the meso- 

 notum has a large undivided stridulatory area and (5) the wing- 

 venation resembles that of no true Prionince. What M. Lameere 

 describes as a lateral margin, consists of a sharp ridge or carina 

 that extends down the side of the prothorax close to, and almost 

 parallel with, its hind margin, approaching more closely in fact to 

 the hind margin at its lower end than at its upper. Such a ridge, 

 though less feebly developed, is not uncommon in the Cerambycince, 

 and is to be found co-existing with the true lateral margin in some 

 Prionince,
