Hedychrnm viricle Cresson, Proc Ent. Soc. Phil, iv, 1865, 306, 9- 

 Hah, — Colorado, Dacota, California, (Coll. Am. Ent. Soc.) Colors 

 almost wholly green. In the subconical and pinched abdomen this 

 approaches to Elampus. Length 3^ lines. 



Hedychruni Liouisianise n. sp. — %. — Color green, spotted with blue 

 on the occiput and prothorax, and with violaceous reflections in the middle of 

 tergum; tegulse and venter purple; apical half of wings subopaque: basin of 

 face with cross striae, and a polished space at summit; mandibles long and 

 stout, with two feeble incisions within; head and thorax with large close 

 punctures; postscutel rounded behind, its edge closely set with large punc- 

 tures; the declivity to the dividing ridge of metathorax abrupt, the first side 

 foveola small, longer than wide, the second very large; tergnm with moderate 

 separated punctures, a narrow polished band at apex and base of each seg- 

 ment, the margin of third segment slightly hollowed in middle and obtusely 

 angulate at sides; venter purple, basal third of each segment shining, re- 

 mainder dull with punctures and coarse hair; hinder femora purple, covered 

 before with dense whitish hair; apex of tibiae and the tarsi brownish; claws

Hah. — Louisiana, (My own collection and that of the Am. Ent. 

 Soc.) Two specimens. 



Hedyclirum violaceum Brulle, Hym. iv, 51, 2, % . 



ffab.— Conn., Del, Va., Mex., (Coll. Am. Ent. Soc.) I find no 

 male which coincides with BruUe's description of violaceum, but 

 several females. So with R. asjyeritm, I find very many males and 

 no females. To avoid making new species, I have thought best to 

 consider the violaceum of Brulle as a female. Very possibly the two 

 are the sexes of one species. 



Hedyclirum aspertim Brulle, Hym. iv, 52, 3. 



Mah.—Gouu., Pa., Va., Dae, Mex., (Coll. Am. Ent. Soc.) This 

 presents several variations in form and punctures. 



S . — Apex of third segment of tergum obtusely rounded between 

 the two outer obtuse angles; surface of first and second segments 

 (except apex of second), with closely set moderate, deep punctures, 

 growing larger toward apex of second and on third, posterior femora 

 green. 



Var. a. — S . — Apex of third segment between the outer obtuse 

 angles convex nearly in the arc of a circle, or a little more ; a polished 

 space down the middle of first and second segments ; hinder femora 

 purple or violaceous. Mexico, (Coll. Am. Ent. Soc.) 



Var. 6. — S 9- — Apex of third segment subconic; tergum polished, 

 first and basal two-thirds of second segments with small equal shallow 

 separated punctures ; hinder femora of female cyaneous, of male 

 green. Dacota, (Coll. Am. Ent. Soc.)
