A NEW SPECIES OF PARAPHELINUS. 49 



convergent towards the rounded, nearly rectangular, postero-lateral angles of the 

 propodeon. The integument weakly chitinised and smooth or faintly patterned 

 along a narrow middle line ; the pattern beyond the middle line more raised towards 

 the sides and the cells generally longer than broad. Pronotum descending, 

 developed into two weakly connected triangular sclerites ; when flattened, deeply 

 emarginate anteriorly, straight posteriorly, the hind and lateral margins meeting in 

 rather over a rounded right-angle, before which is the deep semicircular spiracular 

 emargination. The longest and stoutest bristle is placed above the spiracle and 

 there is always another fairly stout bristle before the edge half-way from the postero- 

 lateral angle to the middle. Prosternum bare, rectangular, truncate posteriorly. 

 Episternite large, with a minute bristle anteriorly and half a dozen on the anterior 

 articulating projection. Mesonotum distinctly longer than the scutellum, mid- 

 lobe large, the width at the anterior extreme of the parapsidal furrows about equal 

 to the length ; 10 stout coloured bristles in two widely separated rows (4 : 4) about 

 the mid line and one inside each parapsidal furrow anteriorly. Side lobes narrow ; 

 two bristles on outer edge above the tegula, which also bears two bristles. The 

 suture between the mid lobe and scutellum broad, a little curved antero-laterally 

 where the small axillae (one bristle) shortly invade the rather narrow parapside? 

 Scutellum with 4 bristles (2 : 2), wider apart than those on the mid lobe. At che 

 level of the anterior pair but a little nearer the mid line are a pair of clear pustulos. 

 Mesophragma long and narrow, reaching back to below the hind margin of the first 

 abdominal segment. Metanotum and propodeon not carinate, but as both, especially 

 the second, are declivous, about the mid line the latter shows up in a more or less 

 distinct ridge. Metanotum band-like (the smooth lateral hollows small and shallow), 

 present mainly as a broad short reticulated post-scutellum, which is widely angled 

 over the propodeon. The latter as a rule nearly smooth, except media nly ; two 

 posteriorly slightly divergent faint lateral folds, so far apart as to be nearly in line 

 with the sides of the abdomen. Beyond each fold there is a narrow triangular area 

 with a short anterior sulcus ; at the inner anterior angle lies the broadly oval moderate 

 sized spiracle. Sternopleurae : sternum broader than long, pattern various, but 

 rather large, very finely raised ; two minute widely-spaced bristles on anterior edge, 

 and 4 (one near each postero-lateral angle, and one on each side of the mid line) near 

 posterior edge. Between sternum and pleura is a weakly defined edge, obliterated 

 posteriorly (without internal support) and represented by a slight crease in flattened- 

 out preparations. At the anterior end of this crease, and confluent with it for nearly 

 half its length superiorly, there is a strong parabolic internal rib which, beginning 

 at the antero-lateral sternal angle, sweeps backwards, enclosing about four-fifths 

 of the pleural surface, and ends superiorly at the insertion of the forewing. The 

 area thus enclosed is a little more prominent than the posterior (epimeral) region, 

 which is delimited ventrally by a ridge, sloped from above the mid coxa diagonally 

 towards the upper anterior pleural angle and fading out (at about one-fourth) in 

 front of the parabolic rib already described. The pleural surface bears one minute 

 bristle antero- ventrally. The episternite is indicated only by an internal chitinised 

 suture. Prepectus large, antero-posteriorly striate, the cross reticulation nearly 

 obsolete. The internal chitinous rib very near the hind edge. The metapleurae 

 are absolutely bare.
