Genotype, Opliion foUator, V. 



Head posteriorly dilated; clypeus more or less discrete basally, 

 apically siibiiiipressed on either side and bituberculate ; mandibles 

 ^\ith teeth of unequal length ; eyes oval and internally sub- 

 emarginate. Antennje slender and shorter than the body. Thorax 

 scabrous, with the metathorax rugose ; spiracles minute and 

 oblong. Scutellum laterally carinate throughout. Abdomen 

 slender, petiolate and compressed, with the two basal segments of 

 equal length, spiracles of the first beyond its centre, and the third 

 segment shorter; terebra exserted, with the valvule apically 

 clavate. Tibite somewhat stout, wir/h the anterior uuicalcarate'; 

 claws only sparsely pectinate basally. Wings short, with no 

 areolet ; second recurrent emitted from the evenly curved first 

 cubital cell.

The generic characters may be regarded as representing those 

 of the tribe, since but one genus is at present known from India, 

 though Ei(f/Horjnis, Forst. (Verb. pr. Eheinl. 1^68, p. 147), 

 differing in its basally areated metanotum and the second recurrent 

 being emitted beyond the submarginal nervure, has been recorded 

 by Tschek (Verb. z.-b. Ges. 1871, p. G7) from Asia Minor. 



Ten American and three European species of this genus have 

 been described. It differs from all species of Opiiionides in its 

 very short antennae and scabrously rugulose mesonotum. Bridgman 

 and Fitch very correctly regard this (Entom. 1884, p. ISO) as a 

 group of transition between the OPHiOKioEsand the Anomalides, 

 with tendencies to a closer connection with the latter tribe, to 

 which it was iirst relegated by Holmgren (Of v. 1858, p. 322). 

 I have recently shown (Eevis. Ichu. Brit. Mus. 1912) that it can 

 hardly be regarded as distinct from the former, since transitional 

 forms occur in the Neotropical Eegion.
