Ch. Holsatica. Linne. — Ha. Holsatica. Steph. Catal. 216'. No. 2204. 



Ovate, convex, black, shining, thickly punctured : thorax very convex and glossy, 

 finely punctured : elytra also very convex, more deeply punctate than the 

 thorax, each with a round rufous spot near the apex, varying in size and rarely 

 extending to the apex itself: femora black, the anterior sometimes testaceous at 

 the apex: anterior tibiae and tarsi rufous: posterior fusco-piceous : antennae 

 black, with the base rufous. 



Occasionally found in marshy places near London. " Neigh- 

 bourhood of Swansea, by Mr. Jeffreys." — L. W. Dillwun^ Esq.

Genus CCCXCVIII.—Macrocnema, Megerle. 



Antenna 10-jointed, shorter than the body, slender; the basal joint elongate; 

 second and third slender, of nearly equal length, subclavate ; fourth similar 

 in form but longer; the remainder stouter, gradually shortening to the apex 

 and pilose : head very small, transverse, subtriangular, not concealed beneath 

 the anterior margin of the thorax: eyes small, slightly prominent: thorax 

 transverse, subconic, much narrowed anteriorly, the base bisinuated: elytra 

 elongate, attenuated at the apex, generally punctate-striate : body elongate, at- 

 tenuated at each extremity : anterior and intermediate Jemora slender; pos- 

 terior very nmch incrassated : tibiae simple, not dentate ; posterior curved, with 

 the apex obliquely truncate exteriorly ; the tarsi, which are elongate, inserted 

 at the superior margin of the truncation, and consequently remote from the 

 apex of the tibiae, which is spurless. 



Macrocnema is distinguished from ail the other saltatorial genera 

 of this family, by having the true second joint of the antennae ob- 

 literated, as noticed by Mr. Haliday, in the Zoological Journal; 

 the apparent second joint being unusually long; the body is in general 

 somewhat fusiform in shape ; and the posterior tibiae are conspicuous 

 by having the apex very obliquely truncate, with the tarsi — which 

 are elongate — inserted at the upper edge of the truncation. 



A. Elytra punctate-striate.
