3i 8 MEMOIRS ON THE COLEOPTERA 



Jans., and fulveola Bates, which therefore also form part of this 

 group; perhaps schotti Lee., may also belong here rather than to the 

 inda group, but of this I can say nothing further at present. In 

 looking over the published figures on the Biologia plate, it seems 

 evident that mystica Thorns., and iridescens Schaum, may form a 

 subgeneric group different from any here proposed and candezei 

 Jans., is in all probability generically different from Euphoria, 

 because of elytral structure and striation. 



Group VI. 

 Subgenus Euphoria in sp. 



In this group the antennal club is rather small in both sexes and 

 never more than very slightly longer in the male than in the female. 

 The body is feebly rhombiform, never opaque above, the elytra with 

 sparse tomentose spots and lines in all except basalis and fascifera, 

 which species are also aberrant in other respects, as well as in type 

 of elytral coloration. The two costse of the elytra are nearly always 

 distinctly elevated, and the anterior tibiae are tridentate in both 

 sexes, the two lower teeth usually, but not always, more approxi- 

 mate than the two upper. Individuals of most of the species are 

 very abundant, and it seems therefore the most appropriate group 

 to typify the genus Euphoria in its more special sense; the species 

 are, however, more difficult to define and more varietally diversified 

 than in any other group of the genus; those at hand are the follow- 

 ing: 



Elytra uniform in color, generally having small tomentose spots; scutellar 

 sinus of the pronotum deep 2 



Elytra yellow or orange, trifasciate with black, without tomentose spots 

 on any part of the body 9 



2 Pronotum almost punctureless, except anteriorly and broadly toward 

 the sides 3 



Pronotum generally uniformly punctured, excepting a more or less narrow 

 and generally more or less embossed punctureless median line, the 

 hairs numerous but short, coarse; elytra with sparse short stiff setae. 4 



3 Pronotum with an oblique broken vitta at each side, not attaining 

 base or apex, and also the lateral limb, tomentose. Body oblong-oval 

 (9). narrower and slightly rhomboidal (cf), shining, rufo-piceous; 

 head with rather close and moderate punctures, the vertex pilose, 

 the clypeus with a very feeble median sinus at apex; prothorax with 

 the punctures laterally large but shallow and obliquely crescentic, 

 the median parts with a few larger and small punctures remotely
