178 Mr. C. 0. Waterhouse's new 



Mixoehlorus sutwalis, n. s. 



Laete aureo-viridis, crebre punctulatus ; fronte, thoracis elytro- 

 rumque vittis duabus rufo-cupreis. Long. 13 mui. 



Head densely punctured, gently convex ; the forehead reddish 

 coppery, with a green median line on the vertex. Thorax rather 

 straight at the sides, a little narrowed in front, broadest at the 

 posterior angles, which are acute ; rather strongly and moderately 

 closely punctured on the raised parts, densely punctured in the 

 impressions. Scutellum green. Elytra somewhat strongly punc- 

 tate-striate ; the suture with a broad green stripe, which is im- 

 pressed, finely rugulose and punctured ; the two interstices next to 

 the green stripe finely and not very closely punctured, the lateral 

 interstices closely and finely strigose. The extreme margins 

 green ; the epipleural dilatation at the base blue. Prosternum very 

 strongly punctured ; the abdomen rather less strongly and less 

 closely punctured, the apex semicircularly emarginate. 



Hab. Honduras (Brit. Mus.). 



Note. — There is a species of Agrilus from Mexico, 

 which so much resembles this that it might at first 

 sight be mistaken for it. The thorax is, however, 

 uniform in colour, and the punctuation of the elytra is 

 not in lines. 



PERONiEMIS, n. g. 

 Form nearly that of Cinyra albonotata, but with the thorax 

 more convex and more parallel at the sides. Antennal pores 

 anterior. Scutellum transverse and trapezoidal. Sternal cavity 

 formed by the meso- and meta-sterna. Basal joint of the posterior 

 tarsi scarcely as long as the 2nd and 3rd together. Head slightly 

 convex ; antennal cavities small and round. Thorax a little 

 broader than long, very convex anteriorly ; with three rather deep 

 ovate impressions at the base ; the posterior angles slightly 

 diverging and acute. Elytra as broad as the thorax, subparallel 

 for two-thirds their length (slightly sinuate at the sides), gradually 

 and obliquely narrowed at the apex ; the apex of each elytron 

 angular in the middle. First and second segments of the abdomen 

 separated by a suture. The lateral line of the thorax runs obliquely 

 downwards and vanishes in front. 



Peroncemis thoracicus, n. s. 

 Elongatus, subnitidus ; capite viridi, medio rufo-cupreo ; thorace 

 Laete rufo-cupreo, crebre sat fortiter punctato, basi infuscato;
