640 PROCEEDINGS OF THE ACADEMY OF [NOV., 



Winter Park, August 26, two males in a wet drain at Edenton, August 

 20, and one adult and one immature female in undergrowth in woods 

 at Bayville, Ya., August 19. A single male from Raleigh taken 

 August 30, at edge of marsh, is also in the collection. 



The specimens from North Carolina all have the head more or less 

 decidedly reddish, and should be regarded as representing 0. erythro- 

 cephalum Davis if this is considered a valid species, which the present 

 authors believe is not the case. Sufficient material is in hand, from 

 about a dozen localities ranging from New Jersey to north-central 

 Florida to demonstrate to our satisfaction the great amount of indi- 

 vidual variation in this species in the coloring of the head as well as 

 that of the dorsum of the pronotum. The emphasis placed on the 

 ■characters separating erythrocephalum from vulgare in the original de- 

 scription of the former, tends to mislead one, as vulgare is quite distinct 

 in cereal and other characters and glaberrimum with which 

 the specimens of erythrocephalum should have been compared is not 

 mentioned. 



Regarding the presence or absence of spines on the ventral carinae 

 of the caudal femora, the following notes made from fourteen specimens 

 of this species may be of interest: three specimens have 0-0, one 0-1, 

 two 0-2, one 0-3, four 1-2, one 1-4, one 2-4, one 3-3. In size the 

 species regularly increases southward, north-central Florida specimens 

 being extremely large when compared with New Jersey, Delaware 

 and Maryland individuals. Thomasville, (la., representatives are 

 hardly smaller than Jacksonville and other north Florida indi- 

 viduals, while North Carolina specimens are about intermediate in 

 size between those from Georgia and Delaware. As has already been 

 pointed out by the present authors, the length of the tegmina is quite 

 variable. 



Orchelimum agile (DeGeer). 81 



A series of eleven males and two females taken at Sulphur Springs, 

 September 17-29, 1904 and 1905, and a single female taken at Raleigh, 

 September 17, 1904, in upland pasture represent this species. The 

 diversity in size in the Sulphur Springs series is considerable, aside 



21 After carefully examining the literature bearing on the identity of the 

 much-discussed Locusta agilis De Geer, we are compelled to retire Harris's vulgare 

 in favor of the much older De Geerian name, which we believe to be undoubtedly 

 based on the same insect. De Geer's locality was Pennsylvania and Harris's 

 Massachusetts, and a comparison of material from the two States shows no 

 reason for their separation. De Geer's figure is, to us, sufficient to fix the species. 

 We are also of the opinion that Orchelimum gracile Harris is a synonym of 

 Conocephalus fasciatus (De Geer).
