BOOPEDON. 97 



difference between them to warrant their separation. The locality " Central America " 

 is most likely due to an error in labelling, the insect in question probably coming from 

 Northern Mexico or Arizona. 



[4. Bodpedon savannarum, sp. n. 



A long-legged, short-winged, slender insect, most closely related to B. auriventris, McNeill, but differing from 

 that species in its more uniform, darker colour, the more slender hind femora, and the greater inequality 

 of the inner apical spurs of the hind tibiae. 



Head large and smooth, broader than the front edge of the pronotum ; vertex between the eyes as wide as ( <$ ), 

 or a little wider than ( $ ), the smaller diametor of one of them, very shallowly sulcate, and provided 

 with blunt lateral walls and median carina, the lateral foveolae lacking ; face rather oblique in both 

 sexes ; frontal costa very broad and fading into the face just below the ocellus, scarcely or not at all 

 sulcate. Antennae slender, longer than the head and pronotum together, in the <$ reaching the tips of 

 the closed tegmina. Pronotum short, not much longer than the head, with the hind and front edges 

 of about equal width, very gently contracted in the middle ; lateral carina? distinct, arcuate, approaching 

 most nearly in advance of the middle ; median carina distinct, cut back of its middle by the last trans- 

 verse sulcus ; lateral lobes high, the anterior and posterior edges oblique and converging below, the lower 

 edge evenly rounded ; hind and front edges of the disc very broadly rounded. Tegmina and wings 

 abbreviated in both sexes — those of the $ scarcely reaching the apex of the second abdominal segment, 

 subacuminate at the tips, and with their dorsal edges hardly touching ; those of the J reaching the apex 

 of the third segment and with their tips evenly rounded, their dorsal edges slightly overlapping. Hind 

 femora compressed, long and slender, extending considerably beyond the abdomen in both sexes ; 

 hind tibiae provided with 13 spines in the outer row, the inner apical spurs very unequal in length, the 

 inner one quite straight and more than double as long as the outer. 



General colour above greyish-brown, varied with light testaceous and black. • Pace and lower side dirty 

 greyish-white. Sides of the pronotum glossy black, with their front edge, the dagger-shaped streak 

 commencing just above the base of the anterior femora and directed upwards and diagonally backwards 

 to a point near the junction of the lateral carinas, and the back edge of the pronotum itself, yellowish- 

 white. Hind femora below and above testaceous, the outer face grey-brown, but without definite bands, 

 internally with median and postmedian bands, the apices also obscure ; tibiae with a broad pale annulus 

 followed by a dark one, below this dull reddish, the tarsi infuscated. Antennae reddish-ferruginous on 

 the basal half, becoming darker apically. 



Length of body, S 23, $ 34 ; of pronotum, 3 4-25, 5 6 ; of tegmina, J 7, $ 8 ; of hind femora, J 15, 

 $ 22 millim. 



Hab. Noeth America, Central and Eastern Nebraska (Bruner). 

 Found on sand-hills and prairies.]

Hab. North America 1-2 , Arkansas southward into Texas and perhaps into Mexico. 



A specimen before me belonging to the Geneva Museum, from Texas (Boll), is 

 labelled with the MS. name of Boopedon saltator, Sauss. This insect is most nearly 

 allied to B. savannarum, which is found much further northward.]
