52 THE CANADIAN ENTOMOLOGIST 



ON SOME NEW OR NOTEWORTHY COLEOPTERA FROM 

 THE WEST COAST OF FLORIDA.— IV. 



BY W. S. BLATCHLEY, INDIANAPOLIS, INDIANA. 



A further study of the Coleoptera collected by myself during the 

 winter season of 1916-17. and those taken at porch light and sent 

 me in June and July, 1917, has revealed the following species worthy 

 of note or apparenth- undescribed. Unless otherwise mentioned, 

 all the species were taken at or near Dunedin, a town on Clear- 

 water Bay, 21 miles north of St. Petersburg, Florida. 



Platynus octopunctatus Fab. — A single example of this 

 handsome and easily recognized Carabid was taken February 13 

 from beneath rubbish on the site of a recently drained pond. 

 Schwarz records one specimen from Tampa, and Leng has one or 

 two from "Fla." In Western Indiana it occurs frequently in win- 

 ter beneath co^"er on the slopes of sparsely wooded hills. 



Bidessus floridanus Fall. — ^Of this species, which bears a 

 close general resemblance of B. pulicarius Aube, a dozen or more 

 specimens have been taken at Dunedin, and one or two at Sarasota 

 and Kissimmee. Fall's types are from Jacksonville, and it prob- 

 ably occurs throughout the State. 



Celina grossula Lee. — One specimen was taken at Gaines- 

 ville on Februarys 7. Schwarz records it as very rare at Enter- 

 prise and Jacksonville. 



Hydraena marginicollis Kies. — This minute Hydrophilid oc- 

 curs in small numbers beneath immersed boards in the ponds about 

 Dunedin. Like Notomicrus nanulu's Lee. it only becomes visible 

 when it mo\"es. Schwarz lists it as rare, but mentions no definite 

 locality. 



Tropisternus sublaevis Lee. — No previous record of the oc- 

 currence of this species in Florida can be found. It was described 

 from Nebraska and Georgia. Single specimens were taken at 

 Dunedin on January 30 and February 23, and another at porch 

 light on June 20. 



Ditonia carinata Lee. — A single specimen was taken be- 

 neath the bark of a magnolia log at Gainesville on February 7. 

 Recorded from Tampa and Enterprise b>- Schwarz. 



February, 191S
