BEACHTSTOLA. 1% 



Three female specimens. It may reach South-western Arizona in the vicinity of the 

 Huachuca Mountains. However, no members of the genus have been examined by me 

 from that region.

 (G. H. T. Townsend), and Casas Grandes, Chihuahua 8 . 



The present species is apparently confined to the northern part of Chihuahua, 

 Southern New Mexico, and Western Texas. It is much smaller than B. magna, 

 B. intermedia, and B. ponderosa, in which group it falls. None of the specimens 

 examined are uniformly green, as Charpentier's figures would indicate. A specimen 

 received from Mr. Rehn, who reported it as B. magna (loc. cit.), is referred here. 

 The female has three fuscous patches on the outer disc of the hind femora, as in 

 B. mexicana, a character not found in B. magna. 



5. Brachystola mexicana, sp. n. (Tab. II. fig. 4, $ .) 



A moderately small, but very robust insect, with broadly rounded hind margin of pronotum and small tegmina, 

 the ground-colour of which is dark brown, instead of pale ferruginous or testaceous. 



Head of moderate size, much broader below than above, the occiput smooth, rounded ; vertex between the 

 unusually small eyes wider apart than twice the longest diameter of one of them, the fastigium in nowise 

 sulcate nor bordered with lateral carina?, roundly continuous with the prominent frontal costa; the latter 

 evenly expanding below, gently sulcate at and for a short distance above the ocellus. Antennae short, 

 about reaching the middle of the pronotum, their foveas deep and rendered even more conspicuous 

 by being dark piceous in colour. Pronotum ample, the disc depressed on the anterior lobe, bulging on 

 the posterior lobe, sparsely and evenly studded with polished circular elevations, except in the middle 

 near the posterior extremity, where the surface is almost smooth ; median carina high and prominent, 

 except near the posterior extremity; lateral carinas also quite prominent and strongly divergent. Tegmina 

 circular, small, dark-coloured, the veins pale. Abdomen very broad at the base, tapering rapidly, short. 

 Hind femora slender, inner disc dark, the outer one with three dark patches — one basal, one median, and 

 the other apical. Knees with the usual black lunules. Hind tibiae with 10 irregularly arranged small 

 spines in the outer row. 



General colour brownish-testaceous (probably with a greenish tinge in life). Sides of the pronotum more or 

 less piceous. Dorsum of abdomen brunneous, with two paler bands, one on either side near the middle. 

 Other markings as given in general description. 



Length of body, $ , 40 ; of pronotum 15, of tegmina 7*50, of hind femora 19, of antennae 13 millim. 



Hab. Mexico, the exact locality not known {coll. U.S. Nat. Mus.). 



The single specimen upon which the present species is based bears the simple label 

 " Mexico." It presumably comes from the northern portion, perhaps from either 

 Sonora or Chihuahua.
