Fore legs : femur (9 : 2) rather bare, a few subdorsal bristles towards the apex 

 anteriorly, and between the apex and lower basal angle a diagonal row of short 

 bristles (about 12) ; 2 stronger subapical ventral bristles ; tibia (30 : 7) three-fourths 

 of femur, narrow at base, 7-8 of the bristles on the dorsal edge much stronger ; comb 

 with six spines ; first tarsal comb with about 12 spines on the apical half of the 

 joint. Mid legs : femur, 0:1: tibia (10 : 1) at middleand (7 : 1) at apex. 8 short 

 heavy spines at apex ; spur longer than first tarsal joint ; tarsal joints with the 

 following heavy spines : — (1) about 20, (2) 6, (3) 5, (4) 4-5, (5) 2-3 thinner than the 

 others. Hind legs : coxae nearly a^s broad as long (15 : 16) ; tibial comb with 15 

 spines. In the hind and mid legs the first three tarsal joints are in ratio 9:5:4; 

 in the forelegs the second and third joints are a very little longer. 



Abdomen a little longer than broad (about 5 : 4) ; projecting sheath of the 

 ovipositor between one-fifth and one-fourth as long as the abdomen ; surface 

 broadly smooth medianly on tergites 1-0, the overlaps being distinctly rough ; 

 7th tergite (middle portion) delicately reticulate. On each overlap (tergites 1-4) 

 is a single bristle isolated from the posterior rpw, which is broadly separated on tergites 

 1-4 and continuous on 5 and 6 ; the number of bristles in each half of the row runs 

 from 6 (tergite 1) to 4 (tergite 4) ; the setigerous process (tergite 7) bears 3 long and 

 2 short bristles ; between and behind the processes are upwards of 30 bristles. 

 Free poi"tion of sheath to base, as 2 : 5. The 5th sternite bears, besides other bristles, 

 2 widely separated patches of 20 bristles each.

Genus EuxoTUS, Walk. 



Eunolus, Walker, Ent. Mag., ii, 1834, p. 297. 



I have provisionally referred the following species to the genus Eunolus, although 

 the smooth first tergite, slightly shorter than in the genotype, and the peculiar \\ings 

 might justify the erection of a special genus for its reception. It differs obviously 

 and superficially from E. cretaceus, Walk. (loc. cit. p. 298), but as the latter is repre- 

 sented in the British Museum collection only by the unique t}'pe, I have not felt 

 justified in undertaking a critical examination of the species. Few Eunotine genera 

 and species have as yet been described, but the thorough examination which I have 

 been able to make of the external morphology of the present form entirely supports 

 Dr. Howard's suggestion (The Canadian Entomologist, xxviii, 1896, p. 165), as to the 

 affinities of this most interesting Coccid-destroying group. Ashmeads placing of the 

 sub-tribe (Mem. Carneg. Mus., i, 1904, p. 325) amongst the Pteromaltdae seems to 

 me quite inadmissible. 



Eunotus truncatipennis, sp. nov. (figs. 8, 9). 



'^. Shining black, with faintly tinted wings ; on the occiput (more dully) and 

 abdomen dark sub-cupreous ; on the notal surfaces a trace of deep blue. Antennae 

 light reddish-brown, the pedicel darker above. Presternum, pre-episternites and 

 sides of the pronotum pale. Legs : fore coxae (except at the inner basal angle, which 

 is pale), mid coxae entirely, hind coxae from base to apex on dorsal half, all the
