lower down than in the $, at a point just beyond half-way between the toruli and 

 the anterior ocellus. The bristles are fewer on the face, which is broadly bare 

 medianly, and fine from one-half downwards ; as in the $, the triangle between the 

 toruli bears about 12 bristles. 



Antennae : length, '87 mm. ; scape (nearly 4 : 1) shorter than the club (15 : 17) ; 

 pedicel (11 : 10) swollen, two-sevenths of the scape, or one- third of the first funicular. 

 Funicular joints in the ratio 12| : 11 : 9, with a breadth of 7 ; the club in the same 

 scale is 16i, segmented in the ratio 7:6:7; the sensoria are higher and much more 

 numerous than in the $, e.g., the first funicular bears about 40, and the last segment 

 of the club 10. 



Mouth-parts : mandible (4 : 3) broader than in the $. 



Thorax. Everywhere the pattern is more boldly raised, and there are some 

 additional bristles on the pronotum and mid lobe of mesonotum. The propodeal 

 spiracles are oval, and outside them anteriorly the surface is reticulate, not rugose, 

 with 5-6 bristles. 



Wings a little over twice as long as broad ; length 1 mm. ; breadth, "47 mm. 

 The submarginal vein is a little shorter and the marginal correspondingly longer than 

 in the $ ; the submarginal thus bears one longer bristle fewer, and the marginal has 

 1-2 extra added to its rows. In the submarginal cell is a row of a dozen short 

 bristles with 1-2 extra at the apex ; below the marginal (to near the radius) the 

 discal ciliation is distinct, about twice the breadth of the vein. Hind wing : length, 

 '85 mm. ; breadth, '25 mm. Chaetotaxy of veins as in the $. 



Abdomen : sixth tergite narrowly slit medianly, with 6 bristles between the 

 spiracles ; seventh in two quadrate lobes, mth 3 bristles each ; the seventh sternite 

 bears 4-5 bristles on each side below the penis. 



Length, 1"25 mm. ; alar expanse, nearly 2| mm. 



Type — $ in the British Museum. 



Gold Coast : Aburi {W. H. Patterson) ; (a) ex Lecanium sp. on orange, 2 <^^,

This Coccophagine is a typical Aneristus in possessing a short scape and flattened 

 funicle in both sexes. The insertion of the antennae is, however, higher up than in 

 the genotype {Aneristus ceroplastae, How., loc. cit.) and the bristles of the dorsal edge 

 of the tibia are not markedly strong. The species is large and very distinct.

Coccidoxenus coelops, sp. nov. (figs. 2 a-c, 3 a-c). 



$. A large blue-black species with wholly clear wings and distinctly paler tipped 

 ovipositor. 



Head dull violet-black, with metallic reflections at the junction of the scapal 

 furrows, and at each side in the hollows above the mouth-edge. Antennae blackish- 

 brown ; the bullae paler. Thorax like the head, but duller, with green metallic 

 reflections narrowly on the mid scutellum. Wings : both pairs entirely hyaline ;
