taia (Ojpomala biviftata Serv.), in the shape of the fastigium of the 

 vertex. All three species occur in Georgia, so that Thomas' name is 

 unfortunate. M. alacris differs from M. neomexicana in having the 

 fastigium of the vertex still more produced and more pointed, the 

 anal cerci of male a little shorter, the last ventral segment of the 

 same sex less produced, in the lighter coloring, roseate or roseo- 

 ferruginous taking the place of dark fuscous or blackish, and in the 

 greater diffusion of green over the tegmina. 



65. Hippiscus lineatus. Frontal costa expanded at the 

 ocellus, more constricted below than above, expanding toward and 

 extending to the clypeus. Head brownish yellow, mottled with ferru- 

 ginous, the antennas blackish beyond the basal third. Pronotum 

 darker than the head, the superior surface minutely punctate and a 

 little rugulose in short straight ridges, those of opposite sides slightly 

 diverging. Tegmina brownish fuscous, flecked with clustered spots of 

 dark brown, sometimes deepening on the basal half into blackish; 

 they are mostly confined to narrow irregular bands, one of which is 

 premedian, a second lies nearly half way between this and the base, 

 and a third as far toward the apex, beyond which the spots are small, 

 few and irregularly distributed ; the ulnar veins and its immediate 

 borders (forming the angle of the closed tegmina) are pale yellow, 

 forming a stripe nearly the entire length of the tegmina. Wings 

 pale yellow at base, pellucid at tip with one or two small obscure 

 fuliginous spots and black nervules; and in mid- wing a broad black 

 arcuate band, which follows the outer border, diminishing in width as 

 it goes, fully two thirds the way to the anal angle ; the outer limit of 

 this band is a nearly straight line from a point on the costal margin, 

 about three fifths the distance from the base, to the tip of the second 

 or third anal ray; it is divided narrowly by a narrow straight pale 

 yellow stripe (which, as in thetegmina, follows the ulnar vein), and 

 extends broadly above the ulnar vein half way to the base. Hind 

 femora brownish yellow, with a couple of faint oblique darker bands; 

 tibiae dull yellow, darkest below (perhaps reddish in life), the spines 

 black tipped. Length of body, 32 mm.; of antenna?, 1 1 mm. ; of 

 tegmina, 31 mm.; of hind femora, 15 mm. 



Deseribed from a single female, dried after immersion in alcohol, 

 taken by Dr. A. S. Packard in Manitou, Colorado. 



66. Trimerotropis picta. Head yellowish brown, obscurely 

 dotted with fuscous, the front more or less ashen or pallid ; frontal 

 costa deeply sulcate excepting above; lateral foveohe equitriangular;
