S84 







occur beneath about the basal thirds. .Antennae rather stout, pale 

 orange yellow with the third joint reddish except the style-like portion 

 blackish or brownish ; first joint stout, slightly longer than wide, 

 thickest at the tip when it is slightly hooked over the base of the 

 second joint above, clothed with rather dense though short black 

 bristles all over the surface except on the narrow underside which is 

 almost bare but with a very few inconspicuous pale fine hairs and 

 with three or four long black bristles at the tip ; second joint very 

 short and about one-thirds as long as the basal joint, sometimes slightly 

 tinged with reddish, the apical upper prolongation rather long and 

 about as long as the joint itself, the apical circlet of short black brist- 

 les complete ; third joint with a large dorsal tooth just before the 

 middle of the basal annulation, and with a very flat angle about the 

 middle of its lower margin, about the top of the tooth and of the 

 lower angle there are some minute black bristles, the similar but more 

 inconspicuous bristles near the base of the outside ; the basal annula- 

 tion of the third joint very broad, and about one and a half times as 

 long as its broadest part, usually darkened towards the apex ; style-like 

 portion apparently shorter than the basal annulation of the third joint, 

 the basal three annulations usually rather transverse, of which the second 

 annulation is shortest and the third is longest, the apical annulation 

 elongated conical and about twice as long as the first one, each 

 annulation bearing one or sometimes three inconspicuous pubescence 

 near the tip. Eyes bare, but sometimes very inconspicuously pubescent, 

 with the facets all equal, in death deep purplish black with some 

 greenish shimmer ; when seen from above the frontal margin about 

 two-thirds as long as the hind margin which is almost always nearly 

 straight, the outer margin slightly but evenly convex, the top ingle 

 about IOO, the frontal angle about 80 ; in profile oval and the length 

 about two-thirds as long as the depth, the frontal and posterior margins 

 slightly almost evenly convex and the lower margin strongly curved 

 below ; when seen from in front the facial margin very slightly convex,
