never crested; while in the second section the mesopleurae are always 

 more or less striated, and their epimerum distinctly crested. Ten groups 

 constitute the first section, and are separated on the form of the first ab- 

 dominal segment, position of ocelli, and shape of pygidium. The old 

 genus Rhopalum leads off with the first segment of abdomen petiolate 

 and nodose at apex, followed by several groups, the form of their first 

 segment grading into those groups in which the first segment is sessile 

 with the second. The old genera, Blepharip-us and Thyreopus, end the 

 first section and show their relation to the second section by the presence 

 of a small pointed prominence on the epimerum mesopleuralis at the 

 same point where the crest is situated in the species of the second 

 section. The c? antennae in this section offer excellent characters for 

 separating the various groups, either being simply clavate, non-dentate, 

 or the first four joints of flagellum are strongly dentate tKngath; again 

 the sixth joint of flagellum is deeply emarginate at bas<= ...d in one or 

 two groups is in addition strongly produced at apex beneath. The fore 

 tarsi of the male is frequently flattened and dilated, while in other 

 groups they are of the usual form. A number of the old species will be 

 reduced to the synonymy, inasmuch as the sexes of one species have in 

 several cases been described under different names, but this reduction 

 will be more than equaled by the addition of the new species. No further 

 business being presented the meeting adjourned to the annex for refresh- 

 ments. THEO. H. SCHMITZ, Secretary.
