834 THJi LATE MR. M, JACOBY ON NEAV [Nov. 26, 



in front of scutellnm at each side. Setitellttm ti-igonate, foveolate 

 at base, the latter navrowl}^ black. Elytra with strongly produced 

 humeral lobes, extremely finely punctured in shallow grooves ; 

 the interstices flat and impunctate. Prosternum transverse, 

 strongly produced in front ; pygidium closely and rather strongly 

 pimctured, pale fulvous. 



Hah. Brazil. 



This species difl'ers from Crypt, pasticus Suff.,to which it seems 

 closely allied, in the black antennse, the short thoracic depression 

 (which does not extend to the sides), and in the black apex of the 

 tibiae and the similarly coloured tarsi. 



Stegnocephala basalis, sp. n. 



Fulvous ; terminal joints of the antennae and the breast black ; 

 thoi'ax impunctate ; elytra very finely punctate-striate, fulvous, 

 the basal margin black. 



Length 3-3| millim. 



Short and ovate ; the head impunctate ; eyes nearly contiguous 

 in the male, more separated in the female, broadly subquadrately 

 emarginate. Antennae slender, extending to the base of the thorax ; 

 lower three or four joints flavous, rest black ; third and fourth 

 joints elongate, equal, following ones slightly thicker and shorter. 

 Thorax neaily twice as wide at the base as anteriorly, strongly 

 widened at the middle, lateral margins nearly straight posteiior 

 angles acutely produced ; median lobe scarcely marked ; surface 

 entirely impunctate, the anterior portion slightly darkened, 

 obscure, basal portion paler fulvous. Scutellum broadly trigonate, 

 obscure fulvous, impunctate. Elytra slightly narrowed posteriorly, 

 extremely finely punctured except near the basal margin, where 

 the rows commence with a deep impression ; interstices flat, 

 impunctate, the last outer one slightly convex; the base narrowly 

 black, in shape of a transverse band ex ten ding across the shouldeis 

 and downwards along the margins to' a, slight extent. Breast more 

 or less black ; piosternum broader than long, anterior margin 

 concave. 



Hah. Amazons. 



Of nearl}" similar coloration as the variety of S. discoidalis Baly, 

 but distinguished by the entirely impunctate thorax and the 

 finely punctured elytra, even when seen under the strongest lens. 

 Five similar specimens are contained in my collection. 



Cryptocephalus peruanus, sp. n. 



Black ; thorax impunctate ; elytra finely punctate-striate. 



Length 3 millim. 



Oblong, slightl)' narrowed posteriorly ; the head finely granulate- 

 punctate, opaque ; eyes triangularly emarginate ; antennae rather 

 short, black, basal joint fulvous below, long and slender, third and 

 fourth equal, the following joints slightly triangularly widened. 

 Thorax rather long, about one half broader'than long, sides feebly
