1 (2) Clielar claw in lateral view nearly parallel sided, 



hardly curved except at the tip, near which is a dis- 

 tinct prominent tooth H. amphiscepac. 



2 (i) Chelar claw well curved, and without a tooth near 



the apex. 



3 (4) Propodeum rather finely reticulately rugose about 



the middle dorsally, on each side of this with mi- 

 nute shagreening or surface sculpture. . .H. arizonicus. 



4 (3) Propodeum with strong longitudinal wrinkles all 



over its upper surface H. and ax. 



I. Hcspcrodryiiius auipJusccpac sp. nov. 



Ferruginous, abdominal petiole black, the apical segments often 

 more or less infuscate. Three basal joints of antennae concolor- 

 ous u^ith the head, the fourth and fifth white or whitish with a 

 dark line, or the usually dark part may be concolorous with the 

 preceding joints, following joints dark or sordid, the apical one 

 usually paler. 



Head dull, excessively finely and closely sculptured ; second 

 joint of antenngie about half as long as the fourth, the third twice 

 as long as the latter, dull and microscopically sculptured like the 

 head, without any transverse division, but strongly compressed at 

 the sides so as to be bluntly cariniform on its posterior half or 

 two-thirds. Mesonotumi more or less finely and sometimes vague- 

 ly longitudinally rugose, the surface minutely granulate or cori- 

 aceous, the parapsidal furrows easily seen when the thorax is 

 viewed from in front ; scutellum minutely punctate or shagreen ed ; 

 propodeum reticulately rugose, but at the sides with dense minute 

 surface sculpture only, about as long as the mesonotum and the 

 two scutella together.' Front trochanters short and stout, lamel- 

 lae of fifth tarsal joint in a long line extending to, or nearly to, 

 the articulating cavity ; this line of denticles appears to consist of 

 two rows or more, which are more or less confused ; chelar claw 

 with the denticles more spinose, and set further apart, the ante- 

 apical tooth distinct. Abdomen smooth, without any definite 

 sculpture. Neuration mostly pale, yellowish, the transverse ner- 

 vures being more or less dark, and with a dark transverse cloud 

 along them, a second transverse cloud extends across the wing
