appressed cylindrical, blunt ; interspace between mesosternal lobes 

 fully half as long again as broad (cJ*) or subquadrate or transverse (9 ), 

 the metasternal lobes attingent [d') or moderately distant (? ). Teg- 

 mina fully as long as^ generally a little longer than, the pronotum, 

 overlapping, obovate, acuminate, fusco-testaceous or fuscous, in some 

 females fusco-olivaceous, the anal area, or at least its margin next the 

 median area, testaceous or pallid testaceous. Fore and middle femora 

 somewhat tumid in the male, fusco-olivaceous, sometimes testaceous; 

 hind femora moderately heavy, flavo- testaceous, heavily trifasciate 

 with fuscous Csometimes blended on the outer face), besides a fuscous 

 geniculation, the lower face orange ; hind tibiae coral red, the spines 

 black nearly to the base, ii, rarely 12, in number in the outer series. 

 Extremity of male abdomen strongly clavate, much recurved, the 

 supraanal plate broad triangular with a subrectangulate apex, margins 

 feebly flaring basally, and a coarse median sulcus for two-thirds or 

 three-fourths the length, margined by low rather blunt walls; furcula 

 consisting of a pair of minute lobes on either side of the base of the 

 median sulcus; cerci of moderate size, gently incurved throughout, 

 about as broad at ba=e as the frontal costa, tapering to two-thirds that 

 width in the middle, and again expanding to a spatulate oval tip well 

 rounded at apex, and falling far short of the tip of the supraanal plate; 

 subgenital plate of moderate size, the lateral margins strongly concave, 

 being elevated a little basally and rising to the much elevated and 

 flaring apical margin, forming here a stout, blunt, slightly depressed, 

 ascending tubercle.

Fasciatus Series. 



To this series there is a single addition to make, from California, 

 which adds still more diversity to that little homogeneous group. Its 

 position is best marked by separating it bodily from the rest in the 

 table of the brachypterous species of this series (Revision, pp. 1 28-1 29), 

 as follows:
