352 Miss G. Ricardo — A Revision of 



Tlic Walker types of the following species described from 

 unknown localities a're not to be found in the Brit. Mus. 

 Coll., viz. Dasypogoa ap/iidnus, insererts, and occidens, and 

 might well be deleted from the list of species. 



Selidopogon, Bezzi, 

 Zeitschr. Hymeu. u. Dipt. ii. p. 192 (1002). 



Yore tibiae with a curved spine. 



Selidopoijon diadema, Fabr.^ a European species extending 

 to Asia Minor, has a number of synonyms^ among others 

 Dasypogon punctatus, Fabr., which JNiacquart records as from 

 New Holland, stating that a fen:iale he had seen was similar 

 to the European specimens : see Dipt. Exot. Suppl. iii. p. 180, 

 ( 1848). I have not seen any specimens of this species from 

 Australia. 



The genus extends through Europe, N. Africa, Asia Minor, 

 and the American continent.

The type of D. claviventris, Walker, from New Guinea, 

 and D. tasmanica, Walker, from Tasmania, are both species 

 of Bruchyrrliopola, the latter being a synonym of B. inaculi- 

 nevris, Macq. 



U. coHopi>oides, F., from Australia, was unknown to Wiede- 

 mann and Schiner. From the description it is impossible 

 to ascertain what genus it belongs to ; it would seem 

 therefore best to expunge the name from list.
