306 PROCEEDINGS OF THE ACADEMY OF [Juiie, 



antennae burnt carmine, pale and weak proximad. R'onotum with 



the lateral angles marked with maize yellow. Caudal tibise vina- 



ceous pale on the angles; tarsi of all the limbs with 



\r\ff the lateral portions dull purplish brown, the median 



ftl n^ area buff. Ovipositor ochraceous as is also the abdomen, 



y V distal two-thirds oil green, touched with brown at the 



apex, the median suture lined with black for the greater 



portion of its length.

The type of this species is the only specimen seen. 

 Orohelimum glaberrimum (Burmeister). 



This species is represented by seven male individuals taken at five 

 localities: Jacksonville, August 10 and 11, two taken from high bushes 

 in city park; Pablo Beach, August 12, two from wet grassy spots in 

 scrub palmetto barrens ; San Pablo. August 13, one from undergrowth in 

 pine woods; Gainesville, August 17, one from grassy margin of sink- 

 hole; Cedar Keys, August 15, one from salt marsh. 



In size some variation is noticed, chiefly in the length of the tegmina 

 and wings and in the length of the caudal femora. The tegmen and 

 wing variation is quite considerable, the extremes for the length of the 

 exposed combined tegmina and wings being 27 and 34.5 mm. 



Orchelimum nitidum Redtenbacher.i* 



Two males of this species were taken at Jacksonville, August 11, and 

 Palatka, August 19. In both cases the specimens were taken in the 

 city. 



The absolute identification of Redtenbacher's species is attended 

 with considerable difficulty, as the species here described as 0. molossum 

 is in many respects very closely allied. The present authors previously 

 confused these two forms and recorded both as 0. nitidum}^ How- 



'^ Attempts to determine material by the presence or absence of spines on the 

 ventral surface of the caudal femora having proved futile, we are compelled to 

 abandon this character, which in our opinion is generally too indi\'idual in its 

 variations to be diagnostic in this genus. The forms here treated have been 

 recognized chiefly by characters of the genitaha of both sexes, which are more 

 stable and of sufficient diversity to separate the species with the least difficulty.
