(see below p. 81). The date of emergence was not noted. No other specimen nor 

 certain evidence of the recurrence of this species was secured. The Stomatoceras 

 emerged from the puparium by a large irregular hole. Although other similarly 

 fractured pupa-cases were found, Mr. Eminson thinks that the injury might have 

 been caused in these instances by ants. 



Family Encyrtidae. 

 Genus Anastatus, Motsch. (1859). 



Anastatus, Motschulsky, Etud. Ent., viii, p. 116 (1859). 



The species now described and assigned to Anastatus may represent a new genus. 

 The short ovipositor and the nature of the posterior edges of the abdominal tergites- 

 preclude its being placed in Ewpelmus or any of the nearest allies of that genus ; but 

 the species does not run down easily into any of the presently accepted divisions 

 of the subfamily Eupelminae, and it is only because Anastatus seems to offer fewer 

 difficulties that I place this species there. 



Anastatus viridiceps, sp. nov. (ffgs. 8, 4,5). 



5. A pale brown insect, with darker head and banded forewings (fig. 3). Head : 

 metallic green, with faint golden to coppery reflections, especially near the orbits, and 

 on the depressed triangle between the scrobes and the anterior ocellus. Eyes purplish 

 brown, ocelU clear. Antennae like the frons, etc., metallic green, except the scapes, 

 which are non-metallic yellowish brown. Thorax and legs mainly clear yellowish 

 brown. Empodia and claws darker, and a dark superior streak on mid femora, 

 beginning at about one-third from the base and extending to the apex. The heavy 

 spines of the mid tarsi are likewise blackish brown. The elongated mesosternum 

 dark, metallic green. Sharply separated from the non-metallic pale pleurae, while on 

 the notal surface all over the mid lobe and invading the lateral lobes in two narrow 

 strips, the same metallic green coloration reappears, being strongest behind the 

 fading ends of the parapsidal furrows, just in front of the suture, which it fails to 

 reach. Apex of scutellum also slightly darkened and submetallic. Anteriorly the 

 mesopleurae are covered sparsely by a glistening white pubescence. Propodeon 

 dark, with distinct purplish metallic reflections. Wings : forewings mainly tinged 

 with brown, but the submarginal cell and a transverse band from the middle of the 

 marginal vein to the hind margin are hyaline. The apex is clear and the apical 

 region extensively pale from about the ending of the post-marginal, but this is due 

 in part to the lighter chaetotaxy. There is no sharp demarcation between the dark 

 post-median and the light apical areas. Pubescence mainly brown, but round the 

 edges of the clear median band and near the origin of the marginal is a scattered 

 blackish pubescence, seen when the light is allowed to fall from the side. Abdomen : 

 basal one-third (segments 1 and 2) semi-transparent whitish, followed by a dark 

 median band (on tergites 3 and 4). The posterior half of the abdomen concolorous 

 with the legs and thorax ; somewhat dusky on sternites and flanks. 



Head : eyes bare ( x 600, a few very minute hairs not exceeding the facets in 

 height are visible near the edges), approximated on the vertex, where they are 

 separated by about their own diameter (seen from in front) and by twice that distance 

 below. The keel from the lower eye angle is well defined to the clypeal edge. Frons
