STIEAPLEUEA. 107 



4. Stirapleura salina, sp. n. 



A robust insect, with the lateral carinas of the pronotum somewhat interrupted in the middle, and the lateral 

 foveolae of the vertex rounded and ill-defined. The colour is uniform, teing hut little variegated, the 

 hind tibiae dark glaucous. 



Head rather large, slightly wider than the front edge of the pronotum, the occiput somewhat raised above the 

 level of the disc of the latter ; vertex rather wider than half the shortest diameter of one of the eyes, 

 the fastigium deeply sulcate and provided with a rather prominent median carina which enters it from 

 behind, bounded by a high ridge, the hind ends of which approach and continue over the occiput as 

 supplemental carinas almost to the front edge of the pronotum and meet in front in a right angle ; lateral 

 foveolae oblong or rounded, only gently sulcate ; frontal costa rather prominent above, equally and gently 

 expanding downward, in nowise sulcate, but more or less strongly punctate throughout. Face nearly 

 vertical, somewhat rounded when viewed from the side. Antennae setaceous, about as long as the head 

 and pronotum combined. Pronotum with the sides constricted, the hind edge somewhat narrower than 

 the front edge ; lateral carinas inconspicuous, to some extent interrupted in front of the middle, where 

 they approach most closely ; median carina well-defined throughout, cut a trifle back of the middle by 

 the last transverse sulcus ; front edge broadly rounded, hind edge angulate, the apex rounded. Tegmina 

 moderately wide, reaching beyond the apex of the hind femora. The latter rather robust, extending 

 considerably beyond the tip of the abdomen. Claws on the inner side of hind tibiae very unequal. 



General colour plain ferruginous, or ferruginous variegated with brown and dull black. Hind tibiae dull 

 greyish-blue, the base broadly pale. In one specimen the tegmina are rather evenly flecked with small 

 quadrate dusky spots, and the sides of the pronotum and the upper edge of the hind femora show traces 

 of the usual characteristic dusky markings. 



Length of body, $ , 22 ; of pronotum 4*1, of tegmina 17, of hind femora 14-5 millim. 



Hah. Mexico, Salina Cruz (C. C. Beam). 



Two females, captured during the month of December. 



5. Stirapleura meridionalis, sp. n. 



Rather robust, but less so than S. salina, to which it is most nearly related, but differing from that species 

 in having the hind edge of the pronotum more angulate, the hind femora less heavy, and the fastigium 

 of the vertex more prominent. A highly variegated insect. 



Head rather large, wider than the front edge of the pronotum, the vertex about half ( cf ) or nearly two-thirds 

 ( $ ) as wide as the shortest diameter of one of the eyes, the sulcation deep and bordered by a rim almost 

 circular in form in the $ , or cordiform in the <$ , the middle provided with a prominent longitudinal 

 carina, this being continued upon the occiput, where it is accompanied on the first half by two 

 supplemental slightly diverging carinse ; lateral foveolae shallow, broadly elliptical. Pace in the <$ 

 somewhat oblique, in the $ nearly vertical ; frontal costa rather wide, the sides approaching just above 

 the ocellus, otherwise gradually diverging below, coarsely punctate and gently sulcate at the ocellus. 

 Pronotum slightly contracted in the centre, the two ends nearly equal in width ; front broadly rounded, 

 the hind edge angulate ; lateral carinas strongly converging and somewhat obliterated or interrupted 

 mesially, the last transverse sulcus about the middle. Tegmina and wings complete, about as long as ( 5 ), 

 or considerably longer than ( <5 ), the abdomen. Hind femora moderately robust. Tibial claws very 

 unequal in length. 



General colour cinereo-testaceous, varied with dirty white, brown, and black, a characteristic marking being 

 a rather wide, arcuate, pale band on the sides of the head and pronotum, which begins on the lower 

 posterior edge of each cheek and passes upward and backward upon the sides of the pronotum till it 

 reaches and crosses the lateral carinas, terminating at the back edge of sides of the disc. This light- 

 coloured band is bordered above by one of piceous, which narrows from the eyes backwards, and below 

 by a similar but darker band that is directed forward frchn the hind edge of the pronotum ; below this 

 the sides, on their lower edges, are white, with the narrow upward and forward directed extension so 

 frequent in the members of this genus. The face and pleura are pale, more or less heavily blotched with 

 dark brown and black. The disc of- the thorax, the dorsal edges of the tegmina, and the occiput are
