^88 THE CANADIAN ENTOMOLOGIST, 



THE RED-HEADED ORCHELIMUM AND SOME OTHER NEW 



JERSEY ORTHOPTERA. 



BY WM. T. DAVIS, NEW BRIGHTON, STATEN ISLAND, N. Y. 



It seems quite certain in considering Redtenbacher's description of 

 Xiphidiu77i agile, DeGeer, which he considers the same as Orchelimum 

 vulgare, Harris, that he took for his type of the species what is generally 

 identified as O. vulgare. His figure (80) is also a typical vulgare. He 

 says the elytra not at all or scarcely exceeding the hind femora, very little 

 shorter than or equalling the wings. All the femora unarmed. These are 

 characters of O. vulgare, Harris. 



DeGeer's figure, however, shows a rather slender insect, in which the 

 wings are longer than the elytra, and he says the wing-covers are trans- 

 parent. Such an insect, with the hind femora spined on the under side, 

 occurs in New Jersey, and has been identified by Prof. Lawr-ence Bruner 

 as Orchelimum aoile, DeGeer. I am indebted to Prof. j. B. Smith for 

 specimens of this species, which agree very well with DeGeer's descrijjtion 

 and figure. They show no dark median streak down the face. In the 

 Pine Barrens of New Jersey there is another Orchelimum much resembling 

 vulgare, but which may easily be told from it at a distance by its very 

 different song. Upon a nearer approach its most noticeable feature is its 

 very red face, often the whole head being of a blood-red colour. It 

 appears as if the insect had eaten of ripe cranberries and got its head 

 stained with the fruit, for the colour is the same. The Red-headed 

 Orchelimum appears to be undescribed, and may be more particularly 

 characterized as follows : 



Orchelimum erythrocephalum, sp nov. — A medium-sized robust 

 species, with the general colour green ; there are occasional light brown 

 examples. The face, if not wholly red, has usually a red band down the 

 middle, which expands laterally. This area is not definite, and not choco- 

 late brown as in some other species. There is a dark brown dorsal band 

 upon the prothorax and head. The elytra and wings usually exceed the 

 hind femora about 4 mm , and the wings are usually a little longer than 

 the elytra. The hind femora are rarely without erect spines, but are 

 armed with from one to several spines on the under side. The spines are 

 on the outer carina, and are not always of the same number on both legs. 

 The ovipositor is curved, but less so than in Orchelimum vulgare.
