LONGICORN COLEOPTERA FROM BURMA 23 



des Clytus, p. 68, pi. 13, fig. 79), and to P. fulif/inosus, Chevr. 

 — the tj^pe of Chevrolat's genus Amaureslhes. It has a very similar 

 style of marking to the former, but differs from both by the 

 sparser punctuation along the middle of the pronotum, and by 

 the black patch on the middle of the disk. I do not find that 

 Amaureslhes can be distinguished by any definite characters 

 from Pei'issus. The three species just mentioned agree in having 

 their prothorax a little bulged out just behind the middle ; but, 

 so far as I can see , there is no other character of the least 

 generic importance by which they differ from typical species of 

 Pen'ssus. 



The Clytus cinereus of Lap. & Gory (= C. Dwponti (Dej.) 

 Muls.) appears under the genus Clijius in Reitter's Catalogue 

 of European Coleoptera: but if the genus Perissus is to be re- 

 tained , as , for convenience sake , I think it may, it ought to 

 include C. cinereus. 



57. Perissus persimilis, sp. n. P^r ecedenti similis, sed prothoracis 

 lateribus magis parallelis, discoque sine plaga transversa nigra, scu- 

 tello omnino cinereo. Elijtrorum fasciis ante-mediis minus conlortis. 

 Long. 8 97im. 



Two examples taken at Thagatà in Tenasserim. 



This species has at first sight a strong resemblance to the 

 preceding, but may be distinguished by its more parallel-sided 

 prothorax, which is moreover without a transverse black space 

 above. The scutellum is wholly cinereous. The antemedian band 

 of the elytra begins a little behind the scutellum, passes back- 

 wards and outwards, diverging rather strongly from the suture, 

 is then turned slightly forward, and reaches the outer margin 

 without undergoing a second bend. 



58. Perissus mutabilis, sp. n. Capite prothoraceque rufo-ferrugi- 

 neis aut nigris, minute granulosis, griseo subtilissime pubescentibus; 

 prothoracis dorso plaga transversa sub-nuda, margine basali utriii- 

 que albescente; scutello albo, elytris nigro-opacis, fasciis griseis et 

 cinereis ornatis, abdomine et fasciis pectoris cinereis; pedibus anten- 

 nisque nigris, his griseo-pubescenlibus: Long. 8-14 mm.
