joint of flaorellura, if anything, slightly shorter than the length of the two fol- 

 lowing joints united ; pronotiini not so sharply keeled as in the species mentioned 

 above, the lateral tooth small, scarcely developed ; dorsulum with large punctures, 

 sparsest posteriorly; scutelhim with large punctures; mesopleurie strongly punc- 

 tato-striate. the episternal suture marked hy rather strong fovese ; middle segment 

 covei'ed with coarse punctures, sparsest on upper surface, sides indistinctly 

 striated ; al)domen distinctly punctured, particularly on the first dorsal segment; 

 ventral segment 2 closely and finely punctured laterally, in the middle with 

 large, sparse punctures. Black ; mandibles except apex, scape, pedicellum, base 

 of first joint of fiagellura, pronotu'n, tubercles, •^pisternum mesopleuralis in part 

 (this spot sometimes wanting), scutellum anteriorly and two small spots, one on 

 each side just anterior to it, metanotum, apical portion of femora, tibise, tarsi 

 except apical joints, a large spot on each side of dor.sal abdominal segments 1-5. 

 those on the fourth and fifth sometimes uniting within, those on segment 2 usually 

 broadest, yellow ; basal portion of femora generally reddish, sometimes tending 

 to black, and again the femora are almost entirely reddish ; first abdominal seg- 

 ment sometimes more or less rufous; wings subhyaline, darkest apically, on basal 

 portion faintly yellow. Length 13-15 mm. 



'J, . — Space between eyes at base of clypeus less than the width of the latter in 

 the middle; thorax more coarsely sculjitured than in the 9, particularly the 

 middle segment, which is rugoso-punctate on posterior face, and the sides are 

 coareely striated ; fore trochanters beneath produced into a sharp spine ; abdomen 

 more strongly punctured than in 9 ! colored and marked like the 9 > but very 

 variable: the yellow is frequently wanting on episternum mesopleuralis and scu- 

 tellum; tne tibiaj and tarsi are sometimes almost entirely reddish, and in one 

 specimen there are no spots on the thorax and abdomen, except on pronotum and 

 tubercles ; often the second, or second and third ventral segments have a small 

 lateral yellow spot, and the bands (usually three) on segments 4-6 are sometimes 

 broken. Length 10-12 mm. 



Massachusetts ( Packard ) south to Florida and Texas ; Colorado. 

 Smith's anrifrom is identical with this species. I also unite the auri- 

 froiis of Packard with it, the description of which, said to be based 

 on a 9 agrees with Z specimens ; thus it seems to me that the un- 

 usual form of the % antennae in this specie^ has deceived Packard, 

 leading him to sujjpose his specimen was 9 when really of the other 

 sex. The aiirlfroas and collums are surely synonymous with the 

 above, judging from the descriptions, and this view is strengthened 

 by the fact that Say's lO-macidatas is not included in the list of the 

 sj)ecies published by Smith.

 9 . — Head finely and closely punctured ; space between hind ocelli less than 

 that between them and nearest eye-margin, the space between eyes at base of 

 clypeus somewhat greater than the width of the latter in the middle ; first joint 

 of flagellum, if anything, slightly longer than the two following united ; pronotum 

 strongly keeled, the lateral tooth not large, though strong and distinct; dorsulum
