78 Mr. E,. E. Turner's Notes on the Thynnidos, 



pubescence on the front. The posterior ocelli twice as far from the 

 eyes as from each other. Thorax closely and finely punctured, more 

 sparsely on the disc of the mesonotum and on the scutellum ; 

 pronotum much narrowed in front, the anterior margin slightly 

 raised ; mesonotum with the usual two longitudinal sulcte on each 

 side, as long as broad ; scutellum rounded at the apex, raised in the 

 centre ; median segment as long as the mesonotum, very shallowly 

 punctured, with a deep longitudinal depression on each side near 

 the apex. Abdomen slender, about one-third longer than the head, 

 thorax and median segment combined, very sparsely punctured ; 

 the first segment slender at the base, with a deep longitudinal sulca 

 not quite reaching the apex ; the segments very slightly depressed 

 on the apical margin, with a fringe of very short sparse pubescence ; 

 segments 3 and 4 with a tuft of long fulvous pubescence at 

 the apical ventral angles ; segments 2-5 with an impressed trans- 

 verse line close to the base ; the epipygium broadly truncate at the 

 apex, Hypopygium narrow, projecting beyond the epipygium, 

 slightly broadened and strongly rounded at the apex. The first 

 joint of the tarsi is only about one-quarter shorter than the tibice. 



Shining black ; the mandibles except the extreme apex, the clypeus, 

 the orbits of the eyes narrowed continued almost to the posterior 

 margin of the head, a square spot above the base of each antenna, 

 the pronotum very narrowly interrupted in the middle and with a 

 very large black mark on each side, a short longitudinal line on each 

 side near the anterior margin of the mesonotum along the inner 

 sulca, a narrow line above the tegulse, the tegulse, a large irregular 

 mark covering the greater part of tlie mesopleuras, a small spot near 

 the posterior margin of the mesonotum, a spot on the centre of the 

 scutellum and one on each side at the basal angles, the postscutellum 

 except a large black spot on each side, a longitudinal band on each 

 side not far from the middle of the median segment, curving down- 

 wards at the apex and uniting with another longitudinal band on 

 the side of the segment, the sides of the first abdominal segment, 

 almost uniting near the apex, a very large spot on each side of 

 segments 2-5, more or less broadly separated on the middle of the 

 segment, the sixth segment, the epipygium except a spot at the apex, 

 the middle of the first ventral segment, the apical half of segments 

 2-5, the sixth segment with a black spot on the middle, the pro- 

 sternum and the legs golden yellow ; the hypopygium ferruginous, 

 fuscous at the apex. Wings flavo-hyaline, nervures fusco-ferruginous.
