Male Genital Armature of the Dermajptera. Part III. 15 



group belong F. mikado Burr, (fide Zacher). F. piibescens Gene 

 (PL III, fig. 12), and F. lesnei Finot (PI. Ill, fig. 14). 



The next group, according to Zacher, is illustrated so far only 

 by F. ruficollis Fabr., where the virga is of medium length, as in 

 the preceding group, but is elbowed in the form of a U at the 

 junction with the vesicle. F. <vtolica Br. (PI. Ill, fig. 9), and F. 

 sjostedhi Burr (PL III, fig. 10), belong to this second group. In 

 the former, the parameres typical ; virga fairly long, and little more 

 than three times as long as the reniform vesicle, which has a feeble 

 cliitinous reinforcement on the concave side. 



The last group, according to Zacher, is that of F. smyrnensis, 

 where the virga is more than three times as long as the meta- 

 parameres, protruding far beyond them even when retracted, and 

 strongly elbowed into a U at the junction with the vesicle. 



In F. heelzebub the virga is long and sinuate ; it is feebly 

 angled at the entrance into the basal vesicle, which has chitinous 

 reinforcement. The ejaculatory duct is long and coiled (PL IV, 

 fig. 1). 



Subfamily Opisthocosmiin.e. 



Zacher figures no species, but refers to Eimrchus insignis Haan, 

 Opisthocosmia (?) longipes Haan, Cordax forcipatus Haan, and 0. 

 ceylo7iicus Motsch., stating that the genitalia are of the same type 

 as in Forficula. 



I have a few species to add. 



Opisthocosmia ij) pmcilocera Borg. 



Metaparameres broad externally, decidedly convex, apically 

 broadly rounded ; virga about twice as long as the metaparameres, 

 entering the simple vesicle without angle (PI. IV, fig. 2). 



Cordax van kampeni Burr. 



Metaparameres short and broad, convex externally, rather 

 narrowed towards the tips ; virga about two and a half times as 

 long as the metaparameres, strongly elbowed in the form of a U at 

 the junction with the vesicle, which is small, simple, and scarcely 

 inflated. 



The three following species show a more complex type of 

 vesicle, with long sinuous virga. In all three the metaparameres 

 are rather broadened towards the apex, attaining their greatest 

 breadth just before the tips, which are broadly rounded ; the 

 external margin is decidedly convex (PL IV, fig. 3).
