In Marshall's tablesf it runs to Idiasta Foerster, but the 

 second cubital cell cannot be said to be quadrangular, nor the 

 radial cell lanceolate; the recurrent is received by the second 

 cubital cell and the subdiscoidal nervure is interstitial. The 

 ovipositor is much longer. 



In Szepligeti's table:]: it runs to Alysia, section Goniarcha. 

 Pending a thorough revision of the genera of the Alysiinae I 

 have considered it as well to describe this species under Alysia. 



The type will be deposited in the South African Maseuni 

 at Capetown. Paratypes in the collection of the Hawaiian 

 Board of Agi'iculture and Forestry and in the aathor's col-

8. Aphaereta sarcophagae n. sp. 



9 $ Very much like A. mtiscae Ashmead as represented in the 

 Hawaiian Islands, but with the prescutellar sulcus more profound, smooth 

 with a single median raised line at the bottom of the sulcus ; the surface 

 of the propodeum below the transverse carinae usually less rugose than 

 in muscae; sculpture of the first tergite exceedingly variable, but the seg- 

 ment seems to be always shorter, more triangular, the spiracles less 

 prominent and the sublateral carinae more convergent posteriorly, and 

 the second tergite has the sides more divergent behind. 



This species, so far as the material before me goes, averages con- 

 siderably larger than muscae, with the number of antennal joints aver- 

 aging less. In both speies they vary from 19-23. The largest $ is 

 about 3.5 mm., while the smallest is only about 1.75 mm. 



Described from 82 $ $ and 22 S S bred with many others 

 from an undertermined Sarcophaga breeding in human excre- 

 ment at Fish Hoek, on Simon's Bay, near Capetovvm, in April 

 and subsequently on board ship in May and June from the 

 same material.
