ORTHOPTERA— ACRIDIDAE— SYRBULA LEUCOGERA. 869 



second expedition. It is evidently closely allied to the Acrolophitus hirtipes, 

 Say, although the elevated pronotal crest and acute posterior pronotal 

 margin of the latter place the two in different genera. 



Professor Cope has somewhere remarked that specific characters may 

 be carried over from one genus to another. If he is correct in this opinion, 

 this would appear to be a case in point, for the similarity in the specific 

 characters of this species and A. hirtipes is apparent to the most superficial 

 observer. The figure of this species is copied from one engraved by Pro- 

 fessor Grlover. 



By permission of Lieutenant Wheeler, a description of this new genus 

 and species was published in the Proceedings of the Academy of Natural 

 Sciences of Philadelphia, from which it was copied into my Synopsis. As 

 it was given there really as an extract from this paper, it is given here as 

 new. 



SYRBULA. 



This is another of Stal's new genera in which he places a new North 

 American species. I insert his short description of the genus. 



Similar to Mermiria, except as follows : — Antennae slender, filiform, 

 slightly dilated toward the apex ; eyes longer than the portion of the cheeks 

 below them ; presternum destitute of a spine ; posterior lobe of the pronotum 

 strongly punctate, rugulose.

 This is the Oxycoryphus montesuma of Sauss. transferred. 



SYRBULA LEUCOCERA, Stal. 

 Syrbula leucocera, Stal, Recens., 1873, 102. 



Very similar to the S. montesuma, green changing into testaceous gray ; 

 the cheeks and lateral lobes of the pronotum obscure fuscous ; an oblique 

 vitta of the cheeks, margin of the mandibles, the entire broad exterior 

 margin, and a narrow abbreviated interior margin and two abbreviated 

 longitudinal lines of the lateral lobes of the pronotum pale. Elytra griseo- 

 hyaline, sprinkled with fuscous ; veins reddish or fusco-ferruginous ; an 

 anterior intercostal, ferruginous, opaque vitta. Posterior femora with three 

 exterior fuscous spots ; posterior tibia? fuscous at the base, with a broad
