neio species of Eumolpiidce. 45 



face sparingly clotlied witli suberect pubescence. Scu- 

 tellum semirotundate, sides thickened, impunctate, the 

 apex notched ; surface concave, coarsely and closely punc- 

 tured. Elytra much broader than the thorax, broadly 

 oblong, slightly narrowed towards the apex; above convex, 

 transversely excavated below the basilar space, the latter 

 slightly thickened ; humeral callus elevated, obtuse ; surface 

 sparingly clothed with somewhat coarse suberect hairs, 

 coarsely punctured, the puncturing irregular at the base, 

 arranged in longitudinal stride towards the apex, inter- 

 spaces at the base thickened, elevate-reticulate behind the 

 middle, thickened and subcostate. Intermediate pair of 

 tibias thickened and flexuose at the apex, hinder tibiai 

 armed at the apex with a long acute spine. 



Genus Etbiolpus, Weber. 



I have here made an attempt to monograph the genus 

 Eumolpus. For some years past I have been accumu- 

 lating materials for the purpose, my own cabinet having 

 been formed from the collections of the late A. Deyrolle, 

 H. W. Bates, W. W. Saunders and others. 



I am thus in possession of a long series of specimens 

 of several of the more ^-ariable species, without Avhich it 

 would have been almost impossible to fix their specific 

 limits. 



I have found colour of but slight use in separating 

 these insects, but have in many instances discovered 

 good characters in the form of the pro- and meso-sterna, 

 in the form and sculpturing of the apical segment of the 

 abdomen, and (in the male sex) the form of the telum, 

 or $ organ. 



Out of the ten species described, three have been pre- 

 viously characterized, and the rest are new.
