Ooencyrtus pacificus, sp. nov. (fig. 1). 



5. — Head and body shining black, with slight metallic reflections as follows :— 

 Genae dark green, purplish and carmine towards the eye ; upper surface of abdomen, 

 in some lights, very faint dark green ; tegulae like the rest of the thorax. Antennae 

 dark brown, almost black on scape, pedicel and base of funicle ; last two funicular 

 joints lighter ; club entirely pale. Wings almost hyaline, but with a faint tinge of 

 yellow, and slightly browned on the submarginal towards the costa, as well as on 

 the punctiform marginal vein. Legs entirely pale yellowish ; the posterior femora 

 a little browner on the dorsal edge towards the apex. 



Head (fig. 1, b) just broader than deep (15 : 14). Eyes bare ; closely approximated 

 on the vertex, where they are separated by less than the diameter of either, or by 

 rather more than one-fourth of the greatest breadth of the head, but with orbits so 

 widely divergent that the lowermost angles are three times as far apart. Lateral 

 ocelli nearly touching the eyes ; not farther from the margin than one-half the 

 diameter of an ocellus. Scrobes set well below the base line of the eyes ; elongate, 

 triangular, with rounded angles, wide apart, each of the opposed edges aligned with 

 a lateral ocellus and the corner of the mouth-opening ; the lower angle of the scrobe 

 is halfway between the upper angle and the mouth-edge. Clypeal edge occupied 

 by three equal, flatly rounded lobes. Occiput, vertex and frons to about the middle 

 finely reticulate, the pattern so little raised that the surface is shining. Below 

 one-half at the sides and towards the genae the pattern is more flowing and striate, 

 while the mid area above and between the scrobes is perfectly smooth ; there are one 

 or two faint wrinkles above the middle of the mouth- edge ; on the genae the pattern 

 is distinctly raised in ridges, but the surface is hardly duller. On the vertex pos- 

 teriorly are about four short bristles (one behind each ocellus and two between) ; 

 below the anterior ocellus a bristle on each side. There are nine to ten short fine 

 orbital bristles, the last four or five being double. Above the mouth- edge are four 

 bristles (2,2) and on the intra-scapal area are two vertical rows (3-4, 3-4), above 

 which are a final pair, somewhat inwardly displaced. The malar space in front of 

 the ridge is nearly bare, but there are several bristles on the genae. 



Antennae twelve- jointed : scape, pedicel, ring joint, six funicular, and five in the 

 club. The club is not so strongly chitinized as the remainder of the antennae. 

 Scape (7:2) with a subdorsal row of five bristles outside and two rows (5,5) on the 

 inner aspect, besides 8-9 dorsal bristles. Pedicel long and narrow (3 : 1), about 

 three-sevenths of the scape. Ring joint, a minute lamina with a distinct stalk of 

 insertion. Funicle gradually expanded, the first three and the last three joints, 

 respectively, subequal ; the first joint one- third of the pedicel, or five-ninths of the 

 last funicular joint ; the first three funicular joints subquadrate ; the last joint 

 nearly quadrate (9 : 8) and much broader (8 : 5) than the first. Club (10 : 9 : 8) 

 twice as wide as the first, or about one-third wider than the last funicular joint.
