Helcgoimtopus pscudophancs, sp. nov. 



Head black, dull, with slight bluish or purplish tint, the front 

 with excessively minute surface sculpture and some faint larger 

 punctures in the region of the ocelli. Antennae for the most 

 part sordid testaceous or fuscous, the funicle joints sub-elongate. 

 Mesonotum brassy or greenish, shining in some aspects, and 

 with the clothing of white hairs as in the preceding species ; 

 scutellum much as in E. exitiosus, and with the apex very bright- 

 ly metallic in some aspects ; mesopleura deep black or faintly 

 purple-tinged. Legs entirely pale, yellowish. Two basal ab- 

 dominal segments bright metallic green, the rest black or pur- 

 plish-black. Length i mm. 



This description is made from the female, as I have seen only 

 one male, which was not in good condition, but enabled me to 

 make out the antennal character described under the genus. 



HAB : Ohio, U. S. A. ; bred from cocoons of Gonatopits or 

 allied forms, sent by Mr. Koebele. 



Chalccriiiys, gen. nov. 



Plate XIX, fig. I. 



Dififers from either of the two preceding genera in the me- 

 tallic scutellum which is nearly similar in sculpture to the meso- 

 notum, the former not being conspicuously dull and dark com- 

 pared with the latter ; the wings have an exceedingly short mar- 

 ginal vein, a longish stigmal, and the post* marginal hardly de- 

 veloped. In the male the antennal structure is quite different 

 from that of either Echthrogonatopus or Hdcgonatopus, from the 

 latter in the six-jointed funicle, from the former in the very 

 short pedicel, greatly shorter than the large basal joint of the 

 funicle, and from either by the peculiarly former scape, as fig- 

 ured (PI. XIX, fig. 5.) The antennae of the female much re- 

 semble those of Hdcgonatopus and are utterly different from 

 those of Echthrogonatopus. The front between the eyes in the 

 female is wider than in either of these genera, and in the male is 

 very wide, the eyes bing quite small compared with those of the 

 female. The mandibles are tri-dentate, with the inner tooth 

 smaller ; the palpi I have not been able to examine. The axillae 

 appear to be slightlv separated. The eyes are sparsely hairy.
