NOTES ON COCCTD-INFESTING CHALCIDOIDEA— II. 255 



and divided into two, so that the metanotum appears to consist, on each side, of two 

 smooth sunkeii hxteral narrow sclerites : on the propodeon are five carinae (one 

 median, one before and one outside each spiracle) of which the median is extremely 

 short ; that before the spiracle descends abruptly on the inner side, while the surface 

 falls more ceiitly outwards. Beyond the spiracle the surface rises jjently, then falls 

 peipendicularly to the sternum, thus forming the second lateral keel ; viewed from 

 above, both lateral keels project backwards like teeth, and the outer one curves a 

 little outwards as well. The space between the short inner keel and the first lateral 

 one is transversely divided into (tt) an anterior triangular area crossed by 5-G short 

 keels, the surface between these little keels being finely rugulose, and (6) a posterior 

 descending oblong bifoveolate area ; these two pits are generally difficult to see, 

 owing to the rotund first abdominal tergite. The spiracle which lies just anterior to 

 the middle of the area between the lateral keels can with difficulty be made out in an 

 ordinary dry-mounted specimen. The tracheal opening moderate-sized, circular, a 

 little flattened on both sides postero-laterally, and over-arched by a thin operculum 

 of chitin, the actual opening to the air being a narrow convex slit facing the outside of 

 the first lateral keel : inside the second keel are 5-6 bristles, with 8-9 just outside 

 below. The metapleurac are ridged perpendicularly in fi'ont of the coxae, the ridge 

 being interrupted below the postero-lateral angle of the propodeon. thus forming a 

 small tooth or projection above the coxae (cf. the mesopleurae). 



Wings. Fore wings (fig. 8 a) remarkable for their truncated appearance and the 

 costal notch at the end of the submarginal cell ; two and a half times as long as 

 broad : length, -98 mm. ; breadth, 4 mm. ; submarginal : marginal : radius : 

 postmarginal, as 38 : 9 : 7 : 7. The shape of the \nng and the very faint tinting are 

 shown in the figure, but to give the general effect it has been necessary to show the 

 chaetotaxy of both sides of the membrane simultaneously. It should be noted that 

 all the bristles in the submarginal cell rise belou; even the 3 stouter ones at the apex. 

 The submarginal vein bears 9 bristles, and there is a tenth, very stout, at the junction 

 of this vein with the marginal, situated on a curved knob ; at the edge of the marginal 

 and submarginal combined are about 12 pairs olunecjual bristles, one directed upwards 

 and the other outwards and downwards ; otherwise the marginal, post-marginal and 

 radius are absolutely bare superiorly, but below there are 4-5 bristles nearlv at the 

 edge parallel to the post-marginal ; of these, one commonly appears tlirough the base 

 of the radius. 



Fare legs : coxae about 2:1, pattern coarse and transverse ; in addition to 

 numerous smaller bristles all over the surface, there are 4-5 longer ones rising from 

 the base to the broad apical flange. Femur (11:4) broadest beyond one-half from 

 the base, with numerous short bristles, 2-3 deep, antero-ventrally. Tibia (4:1) 

 wth a median chitinous knob at the apex between the spur and the tarsus ; the usual 

 comb is reduced to 3-4 colourless, antero-ventral spines ; at the apical angle anteriorlv 

 are 3 coloured spines, and there are 3 similar postero-ventrally. The first tarsal joint 

 is peculiar, as the comb (about 20 fine spines) is entirely on the plantar aspect, 

 flanked on both edges by 5-G bristles ; 2 bristles or spines on the base of the tarsal 

 ungues. 31id legs : coxa, 4:3; femur (4 : 1) of the same length as the fore femur, 

 and, like it, with immerous ventral bristles ; tibia (23 : 4) with 3 spines both a nteriorly 

 and posteriorly on the ventral half at the apex, the anterior more \\idely spaced ;
