442 MR. BIARTIN JACOBY OX NEW SPECIES [Nov. 28, 



distinguished. M. Olavareau, of Brussels, has sent me specimens 

 obtained in the Province Huallaga, Peru, which again differ in 

 having the elytra! band of a golden coppery tint and fulvous head 

 and antennae. I am, however, unable to see anything more in 

 these differences than one of colour. 



Oedionychis imperialis, sp. n. 



Pale piceous below, the head, antennae, and thorax pale fulvous ; 

 elytra veiy closely and finely pinictured, 23^^i'pli^^^"^'^*^^*^^®o^^' ^^^^ 

 lateral and apical margins and a narrow transverse band at the 

 middle flavous. 



Length 9 millim. 



Head flavous, impunctate ; the frontal elevations broad, con- 

 tiguous ; clypeus strongly raised into a triangular i-idge, the 

 anterior edge of which is very prominent ; antennse pale fulvous, 

 the third joint one-half shorter than the foiu^th (the terminal 

 two joints wanting) ; thorax more than twice as broad as long, 

 the lateral margins strongly rounded anteiiorly, the anterior 

 angles thickened but not dentiform, the sides broadly flattened, 

 the surface minutely and rather closely punctured, pale flavous ; 

 scutellum obscure fulvous ; elytra widened towards the middle, 

 convex, with narrow reflexed lateral margins, the shoulders 

 pi'ominent, the surface extremely closely and finely punctured 

 throughout, purplish violaceous, a narrow sti-aight transverse 

 band at the middle and the lateral and aj)ical mai'gins (the latter 

 slightly moi-e widely so) flavous ; under side and legs pale piceous. 



Hah. Yurimaguas, Peru. 



This species differs from 0. steinheili Jac. (Proc. Zool. Soc. 1880, 

 p. 179) in the pale-coloured antennae, in the differently shaped 

 anterior angles of the thorax, and in the narrow and straight, 

 flavous band of the elytra; the larger size and colour of the 

 elytra separate the species from other nearly similarly marked 

 species, as well as from 0. hifasciata Baly, which has also differently 

 coloured antennfe and a black apex to the posterior femora. 



Oedionychis occipitalis, sp. n. 



Testaceous, the base of the head and the terminal joints of the 

 antenvase black ; thorax impunctate ; elytra microscopically punc- 

 tured, testaceous, a transverse band at the base connected at the 

 suture with another broad band below the middle, black ; the breast, 

 abdomen, and the posterior tibise more or less piceous or black. 



Var. a. The elytral bands not connected at the suture. 



"Var. h. El}i3ra with a spot near the scutellum and an elongate 

 larger spot below the middle, black. 



Yar. c. Elytra entirely testaceous. 



Length 4-5 millim. 



Head impunctate, black at the vertex, the lower jDortion 

 testaceous, fi'ontal elevations broad, eyes large ; antennje slender, 

 the lower four or five joints testaceous, the others piceous, third
