INSECUTOR INSCITIJE MENSTRUUS 137 



cubital and second discoidal ; tubercles and tegulae reddish, legs 

 black with white densely plumose hairs ; knees and extreme 

 bases and apices of tibiae reddish, tarsi becoming somewhat 

 reddish apically ; claws toothed at base ; abdomen closely punc- 

 tured, the punctures almost as coarse as those on mesoscutum ; 

 apical margins of abdominal segments reddish ; segments 2-4 

 with apical margins slightly emarginate medially; sixth seg- 

 ment with a pseudopygidium ; abdomen with white densely 

 plumose pubescence as follows : Sides of segments 1-6, apical 

 itiargins of segments 1-2 ; a pair of spots on segments 3-5 ex- 

 tending to base of segment. 



Type locality, La Quinta, California. 



Type, Cat. No. 20830, U. S. Nat. Mus. 



Described from one specimen collected by F. R. Cole and 

 labeled 4.14. 



Much smaller than fulviventris Cress., from which it also 

 differs in having the abdomen dark, first joint of flagellum only 

 slightly longer than pedicel (it is twice as long in fulviventris), 

 darker anterior and middle legs, etc. 



Named in honor of Mr. E. T. Cresson, Sr. 



Neopasites fulviventris Cresson. 



When in Philadelphia recently I made a few notes on the 

 type of this species which may aid in the identification of it. 

 The mandibles are bidentate at apex ; the labrum medially near 

 base with a short spicule ; scape very short, the relative lengths 

 of the first few antennal joints can be expressed by the follow- 

 ing figures: scape 11, pedicel 4, first joint of flagellum 8, sec- 

 ond 5, third 4; first cubital very slightly longer than second; 

 sixth abdominal segment with a pseudopygidial area. 



Comparing these characters with the new species described 

 shows that certain of them are generic instead of specific. 



Dioxys martii Ckll. 



The type, which is in the United States National Museum, is 

 a male instead of a female as originally stated by Prof. 

 Cockerell.
