half as long as the eleventh. Thorax scarcely wider than long; sides without spines 

 or tubercles, nearly parallel to about middle, then obliquely narrowing to the basal 

 constriction ; surface coarsely, densely confluently punctate, except a median basal 

 space, extending to about middle and free from punctures ; the feeble basal impressed 

 line pubescent with fine, short, cinereous hairs. Elytra about four times as long as 

 the thorax ; sides gradually narrowing to apex from about middle ; apices bispinose, 

 the outer spine longer than the sutural ; surface sparsely and not coarsely punctate, 

 the punctures finer and sparser towards apex, near base a few scattered erect pale 

 hairs. Anterior coxal cavities open behind, feebly angulated externally ; intermedi- 

 ate coxal cavities nearly closed externally. Posterior femora with a short, acute 

 spine at apex. Abdomen darker, pubescent at sides, nearly smooth at middle and 

 very sparsely punctate. Length 26 mm. 



Tucson, Arizona, a single female collected by E. A. Oslar and 

 generously given to me by my friend Mr. Chas. W. Leng. 



Allied to Axestimis from which the nearly closed middle coxal 

 cavities and the scarcely exteriorly angulated front coxal cavities will 

 distinguish Atylostagma. 



The rather short description of the only known species, A. poUttwi 

 White, fits the Arizona specimen very closely, and it is only on account 

 of the distinct bispinose antennal joints that I have given it a new 

 name. The antennse of politiim are spined on the outside from the 

 third joint and dilated on the inside so as to appear serrated. 

 Brothylus subpubescens, new species. 



Brown, pubescence of upper surface not variegated, uniform and inconspicuous. 

 Head short, coarsely but not densely punctate ; interantennal impression moderate ; 

 frontal impression deep. Antennse reaching to apical fourth ; fourth joint about three 

 fourths as long as the third ; the third joint slightly shorter than the fifth ; the follow- 

 ing joints gradually decreasing in width ; very finely and not densely pubescent. 

 Thorax longer than wide ; sides very feebly arcuate, lateral tubercle large, but not 

 prominent ; basal impression broad, but rather shallow ; disk without callosities, but 

 with a narrow longitudinal impression ; surface granulate, pubescence rather sparse, 

 consisting of short cinereous appressed hairs with longer, semi-erect hairs intermixed. 

 Elytra about two and a half times as long as wide at base ; apices separately rounded ; 

 surface not coarsely punctate, punctures finer and almost obsolete towards apex, gran- 

 ulate near base ; pubescence short, appressed and not very dense, permitting the sur- 

 face color of elytra to be plainly seen, intermixed with longer erect or semi-erect hairs* 

 Metasternum and abdomen finely and densely punctate, with some longer punctures 

 intermixed ; pubescence short, not very dense and appressed, intermixed with some 

 longer, semi -erect hairs. Length 14 mm. 



Arizona, one specimen, which I owe to the kindness of Mr. Chas. 

 Palm. 



This species is not exactly congeneric with Brothylus, but the want 

 of sufficient material for comparison induces me to leave it in this 

 genus for the present.
