166 THE ENTOMOLOGIST. 



ON THE GENUS GYMNOPLEURUS, Illiger; WITH A LIST 



OF SPECIES AND DESCRIPTIONS OF TWO NEW 



GENERA. 



By John W. Shipp. 



(Couclucled from p. 135.) 



Probably virens, Erichs , will be found to be synonymous 

 with lavicollis, Cast. ; but I have not thoroughly satisfied 

 myself yet on this point. 



Wahlhcrgl, Boh., is not quite distinct from splendeiis, although 

 regarded as such by some authors. It is, however, a good variety 

 of sjdcndcns. 



I have placed tlioracicus, Har., as a var. of ignitm, Klug., as I 

 have seen varieties which are intermediate between the two, and 

 I only regard thoracicus as the extreme highly-coloured form of 

 ignitus. 



The existing genus may be further divided as follows : — 



A. Species having the posterior angles of thorax produced 



into a distinct obtuse point, and having the basal half 

 of the lateral margins of thorax strongly emarginate 

 and slightly refiexed. Body generally flatter. First 

 segment of abdomen with the side margins straight or 

 slightly convex, edged with a very strong longitudinal 

 carina. Frontal carina never extending past the disc 

 of head - - - Paragymnopleunis , Shipp. 



B. Species having the posterior angles of thorax blunt, 



basal half of lateral margins of thorax bicarinate. 



First segment of abdomen concave, with no marginal 



carinse extending the whole length ; the carina being 



broken and evanescent in the centre. Frontal carina? 



produced at the base of head, convergent. 



a. Frontal carinas always visible. Epipleura of elytra 



not produced into a spine near the humeral 



angles . - . . Gymnopleurus, 111. 



h. Frontal carinas obsolete or nearly so at base of head. 



Epipleura of elytra produced into a short sharp 



spine near the humeral angles. 



Spinogym iwplcurus, Shipp. 



Paragymnopleurus, n. g. 

 Clypeus dentate and slightly reflexed in front, with the edge 

 split into six teeth, the basal two mostly obsolete, or with the 

 front produced and sharply cleft. Frontal carinas only reaching 

 the centre of the head ; sides produced so as to almost divide 

 the eyes. Labial palpi 3- jointed ; the first very large and broad, 

 the second smaller, and the apical joint very small and rounded. 

 Labial palpi and labrum very hairy. Maxillary palpi 4-jointed :
