Not represented in the collections seen from Mexico, but probably occurring in the 

 section bordering the Rio Grande.]

This species has a very similar distribution to the preceding, and possibly is not 

 distinct from it, the two forms being much closer in their structural characters than 

 any of the others, as will be seen by a reference to the above synoptic Table.] 



3. Boopedon fuscum, sp. n. 



This insect, as the name indicates, is of a uniform blackish-brown or brownish-black colour throughout. The 

 only variation from this obscure tint, at least in the specimens at hand, seems to be a slight pale area 

 about the mouth, on the tarsi beneath, and a faint replacement of the uniform dusky hue by a reddish 

 tinge on the hind tibiae. 



General build of the $ short, robust, and without many sharp ridges, deep grooves, depressions, or decided 

 angles; the surface, for the. most part, smooth and moderately glossy or polished. The S more slender, 

 and provided with some of the features mentioned as lacking in the $ . Head a little broader than the 

 front edge of the pronotum ; in the $ robust, smooth, shining, without fastigial sulcus, lateral foveolae, 

 or median carina, all of which, however, are slightly indicated in the <$ ; frontal costa very broad, smooth 

 and well-rounded, shading into the face just below the ocellus. Antennae slightly longer than the head 

 and pronotum together. Pronotum without lateral carinas, the surface more or less polished, although 

 quite strongly and coarsely punctured and furnished with fine tortuous rugae ; last transverse sulcus cutting 

 the coarse median carina at its middle ; anterior edge straight, the posterior edge broadly rounded or 

 subangulate. Tegmina and wings reaching the base of the supra-anal plate ( S ), or only half as long as 

 the abdomen ( $ ), with the apex rounded in the former and acuminate in the latter. Hind femora 

 robust, of medium length, but surpassing the apex of the abdomen in both sexes. Hind tibiae with 10-11 

 spines in the outer row. Tip of abdomen of the $ blunt and strongly upturned. 



Length of body, tf 20, $ 30-34 ; of pronotum, <$ 5, $ 8 ; of tegmina, tf 11, $ 12 - r of hind femora, 

 6 12-5, $ 20 millim.

Although the specimens described are very similar in general appearance and 

 structure to both B. nubilum and B. flavofasciatum, there seems to be sufficient
