318 THE CiNADIAN ENTOMOLOGIST. 



band of pale pubescence, ilie uliimate segmenl witli an almost parallel- 

 sided pygidial area that has rather distinct margins, the lateral margins 

 notched near the apex, the apical margin slightly convex ; ajjical ventral 

 segment nearly smooth and polished, provided with a median, broad, 

 longitudinal channel on the basal half; spurs of posterior tibipe simple, 

 not hooked as in spedosa, to which the 9 bears a close resemblance. 

 Tegument bla.' k ; claws brown ; mandibles and antennpe black ; clypeus 

 and labrum yellow, the clypeal yellow, almost forming a semicircle, the 

 lateral portion distant from the eye for a space equal to the width of the 

 first joint of the flagellum.

SynJialonia actuosa, Cress. 



S 10 mm. Superficially like the ^ o{ Eiiwardsii, but easily distin- 

 guished from that species, also {xova fulvitarsis^ fratei\ honest a, ijiinidens, 

 Cali/orfiica, aibata, spedosa and atriventris by the strong teeth on the 

 seventh abdominal segment. 



Head nearly as long as in Cordleyi \ first joint of the flagellum about 

 one-half as long as the second. 



Thorax dull, dorsulum minutely granular, not punctate ; enclosure 

 of metanotum in sculpture practically as in Cordieyi, but with rather 

 abundant pubescence, so that the sculpture is nearly obscured ; wings 

 differing from Edwardsii in having the first recurrent nervure received by 

 the second submarginal cell a little beyond the middle, and a little more 

 distant from the second transverse cubitus than the space between the 

 insertion of the second recurrent nervure and the third transverse cubitus; 

 posterior tibia; with simple spurs, the longest of which is about as long as 

 the second tarsal joint. 



Abdomen with long white pubescence on the first two segments, this 

 pubescence being concolorous with that of the head and thorax, the 

 succeeding segments, except the penultimate, with black pubescence ; on 

 the penultimate segment the pubescence is very pale golden brown^ 

 except at base, where there is a fringe of brown and black hairs; the first two 

 ventral segments have whitish pubescence, the succeeding segments brown- 

 ish pubescence, with whitish laterally; the seventh ventral segment is nearly
