6. Boopedon diabolicum, sp. n. (Tab. I. figg. 21, 21 a, $ .) 



Rather large and robust, with the face, and the underside and the lower edges of the sides of the pronotum, 

 dirty white, the general colour being dark fuscous or fuliginous. The tegmina lateral, very short, reaching 

 only to the apex of the second abdominal segment, their dorsal edges not touching, and their apices 

 bluntly acuminate. Wings very short. 



Head large and broader than the front edge of the pronotum ; occiput bulging and ascending above the plane 

 of the pronotum ; eyes small, not prominent, acuminate above, their front edge nearly straight, about as 

 long as the cheek below them ; vertex between the eyes a little wider than their shortest diameter, the 

 fastigium gently sulcate, furnished with a faint median carina and bounded at the sides and in front by 

 blunt carina} that meet in a right angle, in front and behind immediately over the apex of the eyes making 

 a short turn inward where they terminate, the lateral foveolse plainly visible from above, elongate ; frontal 

 costa prominent, smooth, a little depressed at the ocellus. Antennae slender, nearly as long as the head 

 and pronotum together. The latter about as wide in front as behind, gently compressed in the middle ; 

 median carina narrow, but moderately elevated and almost equally prominent throughout, cut by the last 

 transverse sulcus about one-third of its length from the hind edge ; lateral carina well-defined on the 

 front edge of the anterior lobe, but gradually fading so as to be entirely obliterated at the last transverse 

 sulcus ; the portions of the surface on the sides of the anterior and posterior lobes punctate and granulate, 

 that on the latter more finely and closely ; anterior and posterior edges nearly truncate. Tegmina and 

 wings very much abbreviated, especially the latter. Hind femora somewhat robust, about reaching the 

 tip of the abdomen; tibiae with 11 spines in the outer row. 



In addition to the colour as described above, this insect has the basal half of the antennae ferruginous and the 

 apical portion infuscated. The hind tibiae are infuscated above and apically, while below and internally 

 they are testaceous or ferruginous, this latter tint gradually passing into dusky and " shining through " 

 in certain lights. 



Length of body, $ , 36 ; of antennae 12, of pronotum 7 '6, of tegmina 7, of hind femora 20 millim. 



Hab. Mexico, Tepic (Gustav Eisen, in coll. Calif. Acad. Sciences). 

 A single specimen. 



7. Boopedon flaviventris, sp. n. 



Of rather small size, but fairly robust in stature. General colour light testaceous or dirty yellowish-white 

 below, darker dorsally. Top of the head and the disc of the pronotum dark fuscous ; sides of the latter 

 , above, and also the knees and a broad preapical band on the hind femora, black. 



Head somewhat broader than the front edge of the pronotum ; occiput rounded, slightly ascending above the 

 plane of the pronotum; face moderately oblique, when viewed from the side slightly arcuate, more 

 distinctly so in the S ; vertex nearly as wide as ( <$ ), or a trifle wider than ( $ ), the shortest diameter of 

 the eyes, deeply sulcate, the lateral carinae meeting in front in a little less than a right angle, the median 

 carina inconspicuous in the tf , nearly obliterated in the $ , the lateral foveolae comprised of a number 

 of confluent coarse punctures, visible from above. Pronotum as wide in front as behind, somewhat 

 contracted in the middle ; the median carina not prominent, cut back of the middle by the last transverse 

 sulcus ; lateral carinae present as rounded shoulders, and followed above by a narrow pale line ; both the 

 anterior and posterior margins of the disc broadly rounded, the latter coarsely granulate along with 

 the sides, the rugosities tending to form transverse wrinkles. Tegmina and wings abbreviated ; the 

 tegmina of the $ lateral, with their dorsal edges not attingent, rounded at the apex, and reaching 

 the tip of the second abdominal segment, those of the d 1 two-thirds the length of the abdomen and 

 overlapping above. Hind femora rather slender in the $ , more robust in the d 1 , surpassing the tip of 

 the abdomen in both sexes. Tibiae with 11 spines in the outer row ; internal apical spurs subequal. 



Top of the head, the disc of the prothorax, and the tegmina dark fuscous, the latter with brown veins, making 

 them appear somewhat lighter. The cavities about the base of the antennae, a narrow band on the sides 

 of the head back of the eyes, the hind border of the latter, the grooves about the labrum, clypeus, and 

 mandibles, a rather broad band along the upper portion of the sides of the pronotum, and the pleura, 

 black. The lateral bands bordered with a testaceous band, which extends backwards from the upper
