Elytra without the red stripes, and with but two or three black 

 epots at tip, Sometimes the spots next ihe eye in front are want- 

 ing, and there are two or three fuscous arcs on the upper part of 

 front, which leads to the next variety. 



Specimens of this variety are at hand from Texas and 

 Mexico. It was described from South America.

O Tettigonia aj/hura, Baker. Psyche VIll, p. 268, 1898. 



Vertex slightly shorter than in the preceding variety. Slightly 

 smaller. 



Color; vertex and anterior 'part of pronotum pale yellow, the 

 marginal band reduced to a spot at apex and a smaller one each 

 side one-third the distance to the eyes, the lines inside the margin 

 and dashes against the eye as in the typical form, median lines a 

 little broader and shorter, often about five spots along the front 

 margin of pronotura. Elytra bright green, red bands obsolete, blue 

 ones pale, black spots at apex small or wanting, nervures slightly 

 fuscous. 



Specimens are at hand from California, and Lower Cali- 

 fornia and Mexico, and Baker reports it from Arizona, 

 This variety represents the same change in form and color 

 for this species that is shown in the Mexican varieties of 

 Qoccatoyia, and the same broadening and shortening of the 

 vertex that is seen in the Mexican forms of bifida and^^r/- 

 punctata and the confiuens form or hieroglyphica. Speci- 

 mens of this form labeled Tettigonia ci/thura, Uhl., in 

 Baker's handwriting are in the National Museum collec- 

 tion. 



^ Genus Draeculacephala nov. gen. 



Similar to Btedrocefi/tala the vertex usually longer and more 

 acutely angled. Face, as seen from side, usually straight, or slightly 

 concave to the middle of clypeus, where it is broken backwards. 

 Disc of clypeus quite gibbous. Pronotum with the lateral margins 

 parallel, narrower than or only equaling the eye. Elytra long, nar- 

 rowing apically greenish, the nervures raised distinct, the apical 

 and the anteapical cells irregularly reticulate veined. Anterior 

 tibiae slender, round. Type of the genus £) mollipes, Say. 



This is quite distinctively a temperate region group,, 

 only a few of the forms extending very far south- 

 ward. The reticulate venation, while only a trivial char- 

 acter, will at once distinguish the typical forms. The
