than wide, wider in front than behind, the sides in front of the eyes 

 straight and parallel, behind the eyes convergent and only feebly 

 convex, (less convex than in the Q minor of the type species), the 

 occipital margin straight and very narrow, but nevertheless distinct. 

 Clypeus very obtusely carinate in the middle. Scale of petiole as in 

 the Q| but thicker. Tibiae as in the Qj. butt less deeply canaliculate. 

 Otherwise like the Qj.. 



9- 18 mm. Colour, sculpture and pilosity as in the 9]., but the 

 spots on the abdomen are obsolete or nearly so. Anterior half of 

 the mesonotum shining. Head narrower, less convex-sided and less 

 emarginate behind than in the Qj.. Mesonotum very convex in front, 

 longer than wide; scutellum as long as wide at the base. Dorsum 

 of epinotum convex lengthwise, merging by a gradual curve into 

 the vertical declivity. Scale cuneiform, higher than wide, the dorsal 

 edge almost trenchant, the anterior face very feebly convex, the 

 posterior face flat. Wings deeply tinged with yellowish brown, ner- 

 vures brown. Otherwise like the Of.

"9|. 14—16 mm. Colour like that of C, caffer Em , or of a pale 

 coloured cognatus, but with diffuse brownish yellow lateral spots on 

 the first three abdominal segments. Head dull, sometimes inclining 

 to rusty-red and sometimes to brown. Thorax dull, abdomen shi- 

 ning. Much brighter than the typical sexpunctatus and with less 

 sharply defined colour contrast than in Liengmei. The spots much 

 smaller than in the latter and not so yellow. Duller than either of 

 those forms but otherwise like them and with hirsute cheeks and 

 setose tibiae. Scale thin. This variety looks deceptively like caffer Emery, 

 but is more compressed and differs from it by the scale and cheeks. 



^ minor, 9*5 mm. This differs from sexpunctatus, Liengmei and 

 var. Hansingi in having the head only moderately narrowed behind 

 and possessing a hind margin more or less like that of maculatus, 

 i. sp. The scale is also much less thick, higher than thick, (as thick 

 as high in Liengmei ^ minor). The colour is of a paler yellow; on 

 the abdomen the segments have each a brown band behind, dilated 

 in the middle and at the sides. . . . Legs and antennae a little shorter 

 than in Liengmei; setae, sculpture and pilosity as in that race, 

 including the hairs on the cheeks.
