308 . JAMES WATERSTON. 



The first three funicular joints bear a single row of rather stout stiff bristles, and 

 the last three bear two such rows ; on the club the bristles are more numerous and 

 hyaline. There are few sensoria, and none till the fourth joint of the funicle, which, 

 like the fifth, bears 1-2 ; the sixth bears 3 ; in the club the arrangement is 4, 3-4, 2. 

 Length of antenna, '55 mm. Mouth-parts : maxillary palpus, 10, 7, 6, 8 ; first and 

 fourth joint of the same breadth ; second and third broader. One hair on the first ; 

 two on the third, four on the fourth ; labial palpus, 8:5:3; four hairs on the third. 

 Mandibles with two minute approximated apical teeth ; the inner edge of the mandible 

 broadly rounded. 



Thorax. — Pronotum cut away obliquely, but almost without emargination above 

 the spiracle ; pattern moderately fine. An anterior irregular row (3, 3) and another 

 posterior (7, 7) of stouter bristles, with a similar row of much finer bristles just in 

 front. Mesonotum coarsely reticulate, raised, especially in front ; with about forty 

 bristles (20, 20). Axillae with pattern fainter and 4-6 bristles Scutellum smooth, 

 without indication of pattern save near the suture ; about sixteen bristles and two 

 clear pustules. Mesopleurae bare, with extremely fine striate pattern, not raised ; 

 mesosternum smooth, except along the middle line, where a regular, rather coarse 

 reticulation is developed. 



Wings. — Fore wings less than three times as long as broad ; in general shape 

 slightly spatulate, and narrow on the basal half. The neuration does not reach 

 beyond the middle of the costa. The submarginal vein (bearing twelve bristles) 

 is basally broad, medianly narrowed, subapically swollen again below, and contracts 

 a little before reaching the costa. The marginal (with three or four larger bristles 

 and a few shorter) is very short and broad, while the postmarginal is rudimentary. 

 The radius, medianly narrow, is almost bare, but in front, the bristles of the membrane 

 come up to the vein, one or two being set at the edge ; behind there is a narrow bare 

 area. The subcostal cell is long and narrow, with numerous minute hairs on the 

 proximal half, and 6-8 much stronger ones apically. From behind the radius, a 

 hairless line stretches to the middle of the posterior edge. In front of this line the 

 wing is evenly ciliated and at one-third from the radius, on the anterior edge, are 

 three short, flattened, strong bristles. The basal triangle of the wing is also evenly 

 ciliated, but the hairs are longer, weaker and more scattered. Submarginal : 

 marginal : radius : postmarginal — 30 : 3 : 6 : 1. Length, '85 mm. ; breadth, 30 mm. 

 Hind wings evenly ciliated ; cilia of basal half much shorter ; submarginal cell 

 practically absent. Submarginal (bare) : marginal (8-9 bristles)— 5 : 6. Length, 

 •60 mm. ; breadth, '15 mm. Legs. — Fore legs : coxae oblong (10 : 7), a little 

 narrower apically than at the base, with, externally, 4-5 transverse rows of bristles 

 containing four each ; on the inside 4-5 bristles along the anterior edge, and one to 

 two above the insertion of the trochanter. Femur anteriorly broadly bare medianly 

 from base to apex, with only six to seven weak, short bristles in a sub ventral row, 

 and about two rows (8-10) of similar bristles below the dorsal edge ; three stouter 

 and longer subapical ventral bristles. Tibia very slightly expanded ; apical comb 

 of seven spines, with two on posterior edge ; comb of first tarsal joint of twelve 

 spines. Proportions of the tarsal joints :— 22 : 15 : 14 : 13 : 20 (with claw). 

 Mid legs : coxa similar to that of the fore leg, but with more bristles outside. Tibia 

 expanded from a half onwards ; nearly three times broader at the apex than at the
