234 Mr. B. Saunders' Synopsis of 



densely clothed with hairs beneath, only just showing above the 

 squama as a short falcate tooth ; a second shari? tooth of the lacinia 

 may be seen just underneath the anterior process of the squama 

 (see PI. XII., fig. 7). Legs clothed with black hans, sometimes 

 intermixed with pale. 



5 and 5 . Very like the 3' in colour, varying from bright orange- 

 yellow, with only a few black hairs on the sides of the 1st and 2nd 

 segments and legs, to almost black, with the exception of the disk 

 of the thorax and the under side ; in structure the J and ^ 

 approach so closely to cognatus as to be scarcely recognisable ; the 

 cheeks between the eyes and mandibles are slightly shorter and 

 broader at the apex ; the apex of the abdomen beneath has a more 

 distinct carina. In colour all the sexes may be known from 

 cognatus by the black hairs on the abdomen and posterior legs, and 

 the less regular style of the pubescence itself, which is in this 

 species longer and more ragged. Length, 10 — 18 mm. 



Hah. Generally distributed and very common. The 

 ^ varies extremely in size.

 with yellow hairs, with a well-marked baud of black hairs between 

 the wuigs ; wings shghtly dusky. Abdomen clothed with yellow 

 hairs, the hairs at the base of each segment slightly darker and 

 brighter than those at the apex ; beneath punctured ; 8th segment 

 narrow, parallel-sided, densely hairy at the apex, which is rounded ; 

 genital armature with the sagittae wide at the base, then narrow, 

 with an inferior process just beyond the constriction, the apex 

 widened out triangularly ; stipites longitudinally carinated ; squamae
