2. Encoptolophus costalis. 



(Edipoda costalis Scudd., Bost. Journ. Nat. Hist., vn, 473; Walk., 

 Cat. Derm. Brit. Mus., iv, 732; Thorn., Syn. Acrid. N. Amer., 112. 

 Tragocepliala costalis Stal, Recens. Orth., i, 119. 

 Known only from Texas. 



3. Encoptolophus parvus nov. sp. This insect is closely al- 

 lied to E. costalis, from which it differs in its smaller size, compara- 

 tively shorter tegmina and wings and in the following other points : 

 the head is less tumid, the fastigium of the vertex much more sulcate 

 and less oblique, the median ridge from the back of the head to the 

 middle of the fastigium much more prominent, the frontal costa deeply 

 sulcate throughout and separated abruptly from the fastigium of the 

 vertex by a not very broad transverse ridge. The disc of the pronotum 

 is not marked by X -shaped pale markings on a dark ground as in E. 

 costalis, but is darker in parallel lines along the lateral carinas, deepest 

 and broadest posteriorly; the brevity of the tegmina is entirely con- 

 fined to the apical portion containing the parallel veins ; the trans- 

 verse pale stripe at their base is much narrower than in E. cos- 

 talis, and followed apically by a uniform fuscous cloud, instead of a 

 cluster of fuscous flecks; the inner transverse stripe is also much 

 narrower ; the wing is less heavily clouded. 



Length of body, 16 mm. ; of antenna?, 7 mm. ; of tegmina, 15 mm.; 

 of hind legs, 11 mm. 2 d", Dallas, Texas, taken Mar. 12 and 24, J. 

 Boll. These two specimens are the only ones I have received and 

 the species appears to be much rarer in Texas than E. costalis.
