Dr. Horn stated that during the past summer he haa received from 

 Mr. W. H. Ashmead a number of species of coleoptera collected in 

 the Florida Keys, among which were several which had not been 

 before known to occur within our faunal limits. 



Hister {Omahdes) Klugii Mars. 



liutela formosa Burm. 



Polycesta angulosa Duval. 



Adelocera mexicana ? Caud. 



Stenodontes exsertus Olio. 



Brenthus anchorago Fab. 



These are all found in Cuba excepting the Adelocera, and of this 

 comparison will be necessary to determine positively its identity. 



Dr. Horn also stated that he had observed the following synonymy 

 while preparing, at the request of Mr. F. G. Schaupp, a synoptic 

 table of Dicablus for publication in the Bulletin of the Brooklyn 

 Entomological Society. 



Dicaelus dilatatus -S'^^, Dejeanii Dej. 



D. elongatus Dfj., simplex Dej., opacus | Lee. 



D. ambiguus Ferte^ opacus Ferte, turhulentus Lee. 

 Gyascutus obliteratus Lee. has been received by iNIr. Ulke from 

 North Carolina. The specimens are, however, smaller than those from 

 California and the sculpture less rugose. 



On p. xiii of these " Proceedings" the measurement of Xemicebis 

 marginipennis Lee, should be 5 mm. 



Mr. E. T. Cresson exhibited specimens of three species of hymen- 

 optera, which he characterized as follows : 



Rhitigaster bicolor.— "J, J. —Black, shining, sparsely clothed with a 

 short, whitish pubescence; face with a more or less deep longitudinal im- 

 pression on each side; mesothorax with the longitudinal impressed lines deep 

 and crenulated, middle lobe, as well as sometimes the lateral ones, with a 

 shallow longitudinal groove; base of scutellum deeply excavated, the exca-
