94 THE CANADIAN ENTOMOLOGIST 



A NEW JAPANESE SPECIES OF THE CYRTID GENUS OPSEBIUS. 



BY F. R. COLE, BUREAU OF ENTOMOLOGY, FOREST GROVE, ORE. 



In a collection of Cyrtidae kindly loaned for study by the Entomology 

 Department of Cornell University I found one specimen which was collected 

 at Harima, Japan. The specimen belongs to the genus Opsebius and is an 

 undescribed species. As far as I know this is the first Cyrtid recorded from 

 Japan. 



The genus Opsebius was described in 1856 by A. Costa from a species, 

 0. perspicillatus, collected in Spain. In the following year Loew -described 

 inflatns from Spain, and not having seen Costa's paper erected for it the genus 

 Pithogasier. In 1870 Loew described 0. pepo from Spain, and in 1871 described 

 O. formosus from the locality termed Gallia, probably southern France. The 

 five other described species in the genus are all from the United States.

The American species are uniformly blackish in body colour. In the three 

 European species the body is black and yellow, and in the Japanese species 

 described below the body colour is metallic green. All species of Opsebius have 

 a characteristic cross-vein dividing the long cell above the discal. This cell 

 may be an outer first basal or the first posterior. Loew left out this cross-vein 

 in figuring the wing of 0. inflatus, but Osten Sacken. examined the type years 

 afterward and found it to be present.
