Mr. C. Davies Sherborn exhibited and made remarks on a copy 

 of the reprint of George Ord's ' North- American Zoology,' recently 

 published in the United States (Haddonfield, New Jersey, 1894).

1. Descriptions of new Species of Coleoptera of the Genera 

 (Edionychis and Asphaera. By Martin Jacoby, F.E.S. 



[Received August 1, 1894.] 



(Plate XXXVIII.) 



In 1860 a Catalogue of Halticidae was published by the Rev. 

 Hamlet Clark, forming one of the British Museum Catalogues. 

 With very few exceptions, no species of (Edionychis and its allies 

 were described, although they amount to some 450 in number. To 

 make a beginning I have described those species which are at 

 present represented in my own collection, and which I have in all 

 instances compared with the specimens contained in the British 

 Museum and named by Clark, retaining in every case the latter 

 author's name. 



The genus (Edionychis almost rivals in number of species the 

 genus Diahrotica amongst the Galerucidce, and is as variable in the 

 coloration as is the case with species of the latter genus. All 

 species of (Edionychis can be separated from the allied genus 

 Asphcera by the shape of the thorax, which has broadly flattened 

 sides, with generally slightly outward pointed anterior angles, the 

 same parts in Asphcera being straighter and produced forward, 

 not outward ; the metatarsus of the posterior legs is also in all 

 cases very short in (Edionychis and the inflated terminal claw is 

 globular. In Asphcera the corresponding joint is longer, and the 

 claw is but moderately swollen ; intermediate degrees I have not 

 observed to any marked extent. With two exceptions, all the 

 species described here are from tropical South America. 



ffiDioNrcHis ALBiPENNis (Clk. Catal.). 



Pale testaceous, the intermediate joints of the antennae and the 

 disc of the thorax black ; elytra very finely punctured ; a spot on 

 the shoulder black. 



Var. a. Obscure fuscous, the elytral spot absent, the tibiae and 

 tarsi black.
