,very deep basal sulcus between them; furcula absent; cerci slightly 

 longer than the supraanal plate, subconical, faintly compressed, a 

 little downcurved apically, tapering with regularity; infracercal plates 

 inconspicuous. 



Body griseo fuscous, mottled, the face and inferior surface of body 

 sordid brownish yellow, feebly punctate with fuscous. Vertex and 

 fastigium brownish fuscous, the lateral margins of the latter feebly 

 enlivened witli orange, and the former mottled or streaked with livid 

 brown. Both thorax and abdomen are heavily mottled with blackish 

 fuscous, much more heavily in some individuals than in others, which 

 is apt to be conspicuous in a pair of subdorsal bands, sometimes con- 

 fined to the posterior edges of the segments, and to leave a narrow 

 lighter dorsal stripe between them; the lower portion of the lateral 

 lobes of the pronotum is always lighter than the upper half, which is 

 often marked by a more or less distinct, sometimes abbreviated, broad 

 black or blackish band, generally deeper in tint on its inferior half. 

 Hind femora blackish fuscous feebly clouded with dull yellowish, the 

 whole under surface and under portion of its outer face clay yellow; 

 hind tibiae light coral red (male) or dark coral red on apical half and 

 extreme base, passing into purplish red on the basal half (female), the 

 spines blackish on their apical half at most. 



Length of body, male, 16.75 mm., female, 21 mm.; antennae, male,

3. BRADYNOTES EXPLETA, new species. 

 (Plate VI, fig. 7.) 



Body similar in shape and clothing to B. hispida, except that it is 

 relatively a trifle stouter at the metathorax, especially in the female. 

 Head broad and full, the vertex gently tumid, the interspace between 

 the eyes nearly or quite twice as great as the least width of the frontal 

 costa, the fastigium strongly declivent, shallowly sulcate, the lateral 

 margins rather prominent, especially in the male, but rounded; frontal 

 costa rather broad, considerably broader than the basal joint of the 

 antennae, feebly sulcate if at all, and sparsely punctate, especially at 

 the margins; eyes as in B. caurus (antennae more or less broken in all 

 specimens seen). Pronotum regularly expanding posteriorly, very 

 slightly in the male, distinctly but not greatly in the female; metazona 

 about half as long as the prozona, the sulci of the former equally but 

 feebly impressed, all cutting the feeble median carina, which is obso 

 lescent on the prozona in the female ; mesonotum nearly half (female) or
