2-joiated, Pronotum porrect, a little shorter tliau the entire mesonotum, the 

 two togetlier barely longer than the head. Prop(jJeal spiracles circular. Winj^s 

 post-margiual, shorter than the radius, and both much exceeded by the mar- 

 ginal. Discal ciliatiou sparse and obsolescent. Fore legs much modified ; the 

 cuxae elongate. Femur oblong, stout. Tibia short, bent, armed dorsally with 

 .sharp peg-like spines. Tarsus normal, slender, as are also the mid and hind 

 legs. In all the tarsi the joints, except the oth, bear a pair of spinose bristles, 

 preapical and ventral in position. Abdomen compressed, tergites deeply in- 

 cised posteriorly. Segments 4 and 5 longest. Spiracles very broadly oval. 

 Ovipositor I'atlier stout, short, decurved. Sternites 1-2 medianiy incised 

 posteriorly, while 3-5 are produced ; the 5th is in profile ploughshare-shaped 

 •and longer than the rest taken together. 



Genotype the following species : — - 



Seres armipes, sp. n. 



A blackish-brown species in which the ground-colour is completely masked 

 'by brilliant blue-greeu metallic reflections, which are strongest anteriorly, par- 

 ticularly on the head. Abdomen duller. Mandibles dark castaneous. Trophi 

 pale. Antennae castaneous : coxae and femora mainly blackish brown. Tibiae 

 and tar.■^i paler. Wings clear, glossy, almost invisible in balsam; veins very 

 faintly embrowned. 



'Head: length (depth) '87 mm.; across the vertex the breadth is h and at 

 5the mouth-edge \ of the length. Eyes ^ as long as the head and separated by 

 I of the breadth across the frons. Toruli distinctly below the base-line of tbo 

 •eyes; small, circular, contiguous. Ocellar triangle a little more than right 

 angled anteriorly. Integument strongly chitiuised, smooth, polished. Frontal 

 •surlace generally bare, but there are a few bristles (minute) along the orbits 

 and one or two above each of the lateral clypeal lobes. Antennae "75 mm. 

 long. Scape slender (7:1), parallel-sided, with about a dozen short bristles 

 ■along the doi'sal edge, and the same number on the inner aspect with about 

 ■8 very minute ventrally. Pedicel (8: 1) not quite half as long as the scape, 

 with about a dozen bristles mainly on the iimer surface. Ring-joints stout, 

 •eiich with one dorsal and one ventral bristle. The normal funicular joints 

 and the club segments are in the ratio 12, 13, 13, 14, 15, 11, 11 ; in the same 

 scale the respective breadths of the funicular joints are 17, 22, 20, 17, while 

 the club is 16 at the first suture. Senaoria numerous, long, and stout: 1st 

 4'unicular with about 12, the 2nd 18, 3rd, 4th, and first two club segments 

 •about 14, while the last segment lias 8. There is a minute cone-sliaped 

 -terminal sense-organ armed with a short apical bristle and others more 

 minute. Trophi: cardo narrow, L-shaped ; stipes bare; maxillary palpus 

 ;8 : 5 : 7, with its greatest breadth (2) at the npex of the 1st joint, all the 

 joints with one moderately long preapical bristle, the third with, in addition, a 

 short terminal bristle j^ the length of the joint itself. Labial palpus (11 : 11), 

 the first joint bare, the second with 2 short preapical bristles and another s as 

 long as the supporting joint. Thorax -\- Fropuileun P2 mm. Pronotum in the 

 form of a truncated isosceles triangle g longer than broad and 5 the length of 

 'the combined scutum and scutellum. Spiracle slightly prominent, with one 

 • stout bristle in front and a number of minute ones scattered irregularly, chiefly 

 anteroluteruUy Parapsidal furrows ending just inside the axillary sutures.
