ATHYSANELLA, A NEW GENUS OF JASSIDS. 



BY CARL F. BAKER, ALA. POLYTECHNIC IXST., AUBURN, ALA. 



Athysanella gen. nov. 



■ Athvsanus-like forms, small, pale fulvous, 

 or grayish ; and rather i^ohust. Head wider 

 than pronotum, verte.\ rather strongly, but 

 very obtusely angulate, the usually convex 

 and more or less transversely depressed 

 vertex broadly rounded on to the front; at 

 apex usually with two large and one small, 

 black spots. Rostrum weak, shorter than 

 clypeus. Clypeus broad, the sides very 

 gradually conveiging to the rounded apex. 

 Ocelli on extreme front edge of vertex and 

 close to e^'es. Front short and broad, con- 

 spicuously wider than clypeus at clypeal 

 suture, the sides sinuate and slightly diverg- 

 ing upward. Lorae about one half width of 

 clypeus or less, and of about the same length. 

 Antennae about as long as head and prono- 

 tum together. Pronotum transverse, about 

 as long or shorter than vertex, feebly trans- 

 versely wrinkled posteriorh' and with a few 

 faint punctures. 



Usually brachypterous. In macropterous 

 individuals the el_vtra about equal the abdo- 

 men iu length, with a broad appendix ex- 

 tending around the apex; with four apical 

 cells including the one between the first 

 anteapical and costa, which should perhaps 

 not be called an apical; with two anteapical 

 cells, the second a part of the basal cell cut 

 off by the usual transverse vein which enters 

 radial cell; the radial, first anteapical, and 

 first true apical directly in line; the first true 

 apical narrow, sides subparallel, the second 

 and third true apicals broad, broadening 

 apically. Wing with the short costal or 

 supernumerary cell distinctly defined; with 

 two apical cells, the second about half the 

 width of first, the submarginal about half the 



width of marginal. The ovipositor always 

 long and strongly exserted. Type Athysa- 

 nella magdalena n. sp. 



This is a small group of closely 

 related western forms, which will in- 

 clude together with several unde- 

 scribed, Atkysanus curtipefinis G. & 

 B., and Eutettlx terebrans G. & B. 

 Of some of the sjiecies here placed in 

 this genus, the fully winged forms are 

 unknown, but other characters make 

 their relationships very evident. 



The head in this genus is much like 

 that of Athysamis in many respects, 

 though more produced than is usual in 

 that genus The characteristic elytral 

 and wing venation throw it at once 

 into a group which includes Aconura, 

 GnatJiodiis and Heitschia. But it is 

 verv distinct from any of these. It 

 should not be confu.sed with that group 

 of Deltocephaltts which includes ar- 

 genteoltis and its allies. These are 

 also dimorphic and possess the elongate 

 ovipositor. It has only a superficial 

 resemblance to Doraiiira, the head in 

 that genus being totally difterent. 



Athysanella magdalena n. sp. Macropter- 

 ous female. Length 3.25 mm. Front little 

 more than one-fifth longer than broad, about 

 twice the length of the clypeus. Clypeus 

 about one-fifth longer than broad. Vertex 

 very obtusely angulate, broadly transversely 

 depressed at middle, length on median
