52G Mr. R. C. L. Perkins on Hawaiian Ophioninae. 



21. (22) Blackish or dark fuscous species (rai-ely witli parts of the 



thorax riifescent) the clypeus, except for the orbital pale 

 line, the legs for the most part, including the coxae, 

 black or dark-coloured. 



(Thorax usiuvlly nearly whollj^ dark, in the type the 

 mesonotum is reddish in front, the scutellum rufescent, 

 as also the propodeum in front of the median tubercle, 

 Scutellum under a strong lens with very tine surface 

 rugulosity and fine sluilknv pmictures, remote and 

 sometimes almost wanting; propoileum normally witii 

 the transverse carina represented only by a median 

 tubercle or short curved line, very rarely extending to the 

 sides, notably smooth in front of the tubercle or carina ; 

 tarsi, tibiae, and antennae or some of these sometimes 

 pale in large examples from Hawaii, dark in equally 

 large ones from Oahu, where a diminutive form diini- 

 diatus. P., is dominant; wings sometimes unusually 

 deeply infuscate and with the discocubital chitinous 

 spot obsolescent (capnodes, P., from Hawaii), antennae 

 very long, even in the $ far surpassing the apex of the 

 spread wings.) E. Duiuicola, Ashm. 



22. (21) Ferruginous species, or if the thorax or abdomen or both are 



largely dark fuscous or blackish, the legs for the most 

 part or entirely and the clypeus remain red or ferruginous. 



23. (24) Scutellum very finely and feebly punctured, the punctures 



remote, the surface more or less microscopically rugulose, 

 often somewhat shining; chithious spot of the disco- 

 cubital cell nearly always distinct (absent in 2 per cent, of 

 examples examined). 



(Face very wide across the eyes, these being very 

 strongly rounded outwardly, the cheeks short; 

 antennae in both sexes extending far beyond the apices 

 of the spread wings. In the $ the carina of the pro- 

 podeum is rarely complete in examples from Hawaii, 

 sometimes altogether wanting ; often represented by a 

 median tubercle, as is normally the case in the (J; in 

 front of the tubercle or carina the propodeiuu is more 

 or less smooth and often somewhat shining ; neuration 

 variable, the basal nervure sometimes meeting the 

 transverse median, sometimes well separated from it, 

 discocubital nervure varjang in curvature so that the 

 discoidal cell beneath it varies in shape.) 



E. lineatus. Cam. 



24. (23) Scutellum comparatively strongly and often closely o
