HYMENOPTEROUS FAMILY STErHANID^. 725 



Habitat : Mindanao, Pliilippines. Type in Museum at Ham- 

 burg. 



c? (?). M. insidiator, Smith. " Male. Length 9 lines. The 

 head and base of the antenn?e feiTuginous ; the former trans- 

 versely striated, with the posterior margin of the vertex smooth 

 and shining, or with a few punctures. Thorax strongly, but not 

 closely punctvired ; wings fusco-hyaline, the anterior and inter- 

 mediate tibiae rufo-testaceous, with the femora obscurely so ; the 

 posterior femora with two stout teeth beneath and six minute 

 ones between them ; the posterior tibiae at their apex, and the 

 tarsi pale rufo-testaceous. The abdomen elongate, lanceolate at 

 the apex, and entirely smooth and shining. Hah. Mysol." 



This species may be best known from the very similar S. coro- 

 nator F. by the sulcus on vertex and entirely black terebral 

 sheaths ; the latter character and the smaller size will distinguish 

 it from S. ducalis Westw. Smith's description of his insidiator 

 is defective, but it may be the male of sidcifrons, which it appears 

 to resemble.
