of liind libiic and tlie tarsi pale yellow; in one specimen the scape is black, witli

I had at least two specimens of the following mixed with the 

 specimens upon which the above description was based, and that is 

 probably true of Packard's material ; at least, the small specimen 

 from Illinois probably belongs to the next. But that did not seem 

 to modify the descriptions in any essential. Of 31 9 specimens, 30 

 have two spots on scutellum ; the abdomen is 8 spotted in 29, 6- 

 spotted in 1, 4-spotted in 1 ; all have the fifth segment of abdomen 

 more or less rufous. Of 42 % specimens, 13 have spots on pro- 

 thorax; 19 have spots on tubercles; the abdomen is 8-s})otted in 6, 

 6 spotted in 7, 4 spotted in 26, and 2-spotted in 1. This may prove 

 to be the same as A. analis Cr. or a mere variety of it.

9. — Closely, rather finely punctured ; prothorax carinate; scutel moderately, 

 postscutel strongly carinate; squama terminating in a curved point, not with a 

 short lateral curved point which does not surpass the base, as in iV. americaua and 

 frontalis; spine broad, excavated, emargiuate; base of abdomen with median de- 

 pression. Black, the face with some glittering hairs, not at all silvery ; mandibles, 

 line on prothorax, tubercles, two spots on scutel, inner edge of squama, some- 

 times extending across postscutel, knees, anterior tibire, middle tibise in front, 

 hind tibiai at base, and front tarsi, six or eight spots on abdomen, yellow; middle 

 and hind tarsi fuscous; antennse, except at base, more or less fulvous; tegulse 

 reddish testaceous, apical segment of abdomen rufous. Length 3-4 mm. 



"J, . — The face with silvery pubescence; no spots on scutel ; middle tibiae more 

 yellow; middle and hind tarsi yellow or whitish, apical joints sometimes a little 

 fuscous; prothorax with more or less evident yellow marks on the sides ; of 9 'J, 

 specimens, the tubercles show yellow in 1 ; the abdomen 4-si)otted in 5, 2-spotted 

 in 4. Length 3 5 mm. 



Carlinville, Illinois ; 3 9,9 ^ specimens. 



This species appears to run smaller than N. americaua. The form 

 of the squama shows a distinct species ; the spine is not so broad as 

 in that species; the ornaments are more yellow; the female has no 

 silvery hairs on face; the prothorax more yellow, the band usually 

 continuous and extending to tu.l)ercles ; the spots on scutel larger.
