ISSIDAE. 

 Capelopterum maculifrons sp. n. Figs. 17, 17a. 



Male. Length 4.3 mm., tegmen 4.8 mm. Vertex broader than long; 

 face slightly longer than broad, inner carinae subparallel to outer, 

 distinct, nearer to the outer carinae than to the middle of face, surface 

 of face finely rugose. 



Head and thorax stramineous or greenish, face speckled all over 

 with small brown markings, clypeus brown over middle, pronotum with 

 brown speckles, hind femora shiny brown, abdomen greenish, pygofer 

 brown. Tegmina greenish brown with a hyaline patch across middle, 

 the border of the hyaline patch being dark brown, whitish speckles in 

 the cells, plainest on hyaline area; wings hyaline, slightly fuscous, veins 

 brownish. 



Genital styles slightly convex on inner edge, nearly straight on 

 outer edge, broadest before middle, apex narrow, truncate, with the 

 outer corner produced and slightly curved. Anal segment short, broad, 

 in profile the ventral margin emarginate, apex rounded in middle, thus 

 making five round projections, one apical and two on each side. The 

 aedeagus is complex (fig. 17). It consists of a tube divided at the 

 apex into two lobes (b) and having a small central lobe (a) on which 

 the gonopore or opening of the ejaculatory duct is situated. Surrounding 

 this is a large, complex organ forming a tube at the base and dividing 

 into several free appendages at the apex. Ventrally there is a narrow 

 projection (c) furcate at its apex, then a broader lobe divided into 

 two (d) at its apex, these lobes bear a smaller projection at the 

 side, from each side of the middle of this lobe, basad of the furcation, 

 arises a long, slender, pointed process (e), still basad of these and 

 near the base of c there is a semi-circular appendage (f) on each 

 side, joined to the main body at its middle. From the dorsal side 

 arises a broad plate divided into a pair of pointed lobes (g) and a 

 median lobe (h). From near the point where the trifurcation takes 

 place arises a pair of curved processes (i), and basad of these a pair 

 of strong, pointed processes (k). 



It is impossible to homologize these processes at the present 

 time and useless to name them. 



Female. Length 5 mm., tegmen 5.7 mm. In profile abdomen concave 



at base, convex and rounded at apex with the last visible tergite 

 overlapping the greater portion of anal segment; anal segment curved 



to a point at apex; pregenital plate with hind margin sinuate in 

 middle. 



Color similar to male, but the hyaline spot and its border not so 

 evident.
