A NEW SPECIES OF PARAPHELINUS. 53 



7 (8). Club just longer than pedicel, third funicular joint about twice (5 : 3) as long 



as the second . . . . . . . . . . . . xiphidii, Perk. 



8 (7). Club distinctly shorter than pedicel, third funicular not nearly twice (4 : 3) as 



long as the second . . . . . . . . . . perkinsi, sp n.. 



The following notes refer chiefly to the more minute specific differences between 

 the females. It will be noted that the new species is more hirsute than the others. 

 The males are so easily separated by the characters given in the key and figures that 

 minor differences are not now described, but the dimensions of the antenna and wings 

 have been stated. The legs of three of the species are compared in a concluding 

 paragraph. 



Paraphelinus xiphidii, Perk. (1906). 



$. Head : in profile (fig. 1, b) the vertex and upper frons are about four-fifths of 

 the depth ; where the fipns is swollen out to its greatest extent the length and depth 

 are about equal. On the gena the reticulation is drawn out, and there are 12-15 

 short scattered bristles up to the insertion of the episternites. From above (fig. 1, a) 

 about one-half as long as broad, the proportions across the vertex at the posterior 

 ocelli are 6:11, and in front of the anterior ocellus, where the eyes are nearest, 5 : 12 ; 

 wider than thorax (22 : 19). Keticulation of vertex transverse, more regular 

 anteriorly, three minute bristles in ocellar triangle with 2(1:1) stronger ones between 

 each pair of ocelli, the bristles close to the ocelli. Behind the posterior ocelli the 

 vertex bears six stouter bristles (2,2,2), the middle pair in advance of the lateral pairs, 

 and there are also 6-7 minute bristles at each side on the rounded edge above the 

 temples. Between the orbits, a lateral and an anterior ocellus are 4-5 bristles. 

 The frons bears along the orbits (between the keel and the level of the anterior ocellus) 

 about a dozen bristles, the lowermost fine hyaline, 4-5 of the uppermost dark and 

 stouter. Between each upper row of stronger bristles and the mid line are about 



9 similar bristles (5, 4). The greater part of the face below is bare and faintly reticu- 

 late. Between and above the toruli 6-8 pairs of bristles, one pair above the clypeal 

 edge and 3-4 (single) inside the genal keels. 



Antenna (fig. 2, b) : length, '37 mm. ; bulla (3:1) over one- third (5 : 14) of the 

 scape. Scape -f- bulla equal to pedicel -f funicle. Pedicel just over half (23 : 42) 

 the scape ; 1st funicular (8 : 6), 2nd (12 : 7), 3rd (20 : 10), club (44 : 12). The club 

 distinctly longer than the funicle (11 : 9), equal to (or if carefully measured, just longer 

 than) the scape, and bearing 4-5 long sensoria. The scape with 4 ventral bristles, 

 otherwise like perkinsi, except that there are only about a dozen bristles posteriorly. 



Thorax : pronotum with the spiracular emargmation occupying about two-ninths 

 of the lateral edge ; between each stout bristle on the posterior edge and the mid 

 line are two weaker ones, 2-3 minute on each side of the mid line, and 6-8 obliquely 

 across each half. Pattern everywhere distinct, traceable to the mid line. Mesonotum 

 (14 : 15) half as long again as the scutellum (3:4). Mid sternal region distinctly 

 separated from prepectus. Sternal pattern very faint but the cells large and sharply 

 outlined when finely focussed. 



Propodeon nearly twice as long as the metanotum (11 : 6) which is coarsely trans- 

 versely reticulate ; pattern very faint medianly, more distinct towards the lateral 

 ridges. Spiracle circular, with two minute bristles at the outer edge of the rim.
