Hab. Mexico, Chapultepec {L. Bruner). 



This beautiful little insect was found by the author in the fields about the outskirts 

 of Mexico city, where it occurred in moderate numbers. 



[8. Encoptolophus californicus, sp. n. 



An insect of moderate size, but rather slender in build, and with an oblique face, when viewed laterally. The 

 $ is largely green and the 6 wood-brown. Both sexes show the usual dark markings," though in a less 

 degree than in most of the other species of the genus. Pronotum with the lateral carina? very prominent 

 and straight, continuous, gently converging in front ; median carina cut a little in advance of the middle 

 by the last transverse sulcus, which alone shows on the disc ; hind margin of the latter somewhat obtuse 

 in both sexes. Tegmina and wings surpassing the tip of the abdomen in bofh sexes. Hind femora about 

 normal ( $ ), or somewhat enlarged ( S ). Occipital carina prominent and continuous to the front edge of 

 the pronotum. Vertex narrow and projecting prominently forward in advance of the eyes.

Hab. Noeth America, Los Angeles, California (B. W. Coquillett : d $ ). 



This locust should be included in the present work on account of its habitat being 

 in such close proximity to Mexican territory. It bears some resemblance at first glance 

 to the different species of the genus Chortophaga. The male in particular has this 

 appearance.]

In this insect the body is somewhat cylindrical, the median carina of the pronotum is sometimes rather weak, 

 but equally prominent on both lobes, and the lateral carinas are for the most part inconspicuous and 

 greatly interrupted in advance of the principal sulcus. In some individuals the disc on each side of the 

 pronotum is irregularly tumescent in advance of the main sulcus. The vertex between the eyes is some- 

 what narrower than their shortest diameter and fairly deeply sulcate, pyriform in shape, and provided 

 with rather prominent bounding-walls, while the posterior longitudinal or occipital carina is nearly 

 obliterated. The pronotum is shorter than usual, and has the anterior lobe cylindrical, but the hind lobe 

 rapidly expands and is provided with well-marked shoulders ; the posterior edge is nearly a right angle, 

 sometimes a little more or less. Tegmina extending beyond both the tip of the abdomen and the apex of 

 the hind femora in the two sexes. Hind femora somewhat robust, but of normal length. 



General colour ferrugineo-brunneous or greyish-brown, with darker markings on the tegmina and hind femora. 

 The dorsal edges and the apical third of the former irregularly mottled with small fuscous dots, otherwise 

 with the rather definite dark markings common to the members of this genus. Hind femora showing 

 traces above and towards the apex of dusky bands. Hind tibiae with their base broadly pale, for the rest 

 glaucous. Wings yellowish-hyaline, their apices and outer posterior border tinged with fuliginous, the 

 veins and veinlets of this area infuscated, the stigma large and strongly tinged with black.
