ART. 15. REVISION OF THE MUTILLID WASPS MICKEL. 27 



tridentate ; clyj^eus bidentute mediall}', closely and rugosely punctate ; 

 antennae separated at the base by a distance very slightly greater 

 than half the length of the scape ; first segment of flagellum slightly 

 longer than half the length of the second segment ; front with close, 

 confluent punctures; vertex with punctures more separated than on 

 the front and more or less confluent: genae with close, confluent 

 punctures; postero-lateral angles of head rounded; eyes slightly 

 ovate: distance between hind margin of eyes and postero-lateral 

 angles about two-thirds the longitudinal diameter of the eyes; rela- 

 tive widths of head and thorax 11-13. 



Thorax black, clothed with sparse, long, erect, black pubescence: 

 pronotum, mesonotum and scutellum with close, confluent punctures : 

 dorsum and posterior face of propodeum reticulate ; tegulae slightly 

 convex, punctured on the basal third, polished on the apical two- 

 thirds; humeri rounded; propleura rugose; mesepisternum and me- 

 aepimeron punctured and striato-punctate ; metapleura for the most 

 part polished, slightl}' transversely striate on the ventral half; sides 

 of propodeum coarsely, transversely striato-rugose. 



Abdomen black, clothed with sparse, long, erect, black pubescence ; 

 first segment completely sessile with the second: first tergite with 

 small, separated punctures; second tergite with deep, distinct punc- 

 tures separated by about their own width ; tergites 3-6 with distinct, 

 separated punctures ; second sternite with distinct, sparse, irregularly 

 distributed punctures. 



Wings very dark; cell R4 almost obsolete; vein M 3+4 received 

 by cell R5 a little before the middle. 



Legs veiy dark blackish-red, clothed with sparse, black pubescence. 



Holotype.—M.'sX^, July 31, 1909, Willcox, Arizona (A. K. Fisher).

Superficially this closely resembles anthracina Fox but may be 

 at once distingaished from that species by the coarse sculpture of the 

 sides of the propodeum. Considering the structure of the genitalia it 

 would seem to be most nearly related to oceola Blake, -flavida Blake 

 and aureov.estita Bradle}'. 



2G. PSEUDOMETHOCA MERITORIA, new species. 



Female. — Ferruginous; length 9 mm. Head ferruginous, very 

 sparsely clothed with semierect, short, golden pubescence, and a few 

 erect hairs; the pubescence of the genae more of a silvery color; 

 mandibles tridentate; antennae separated at the base by a distance 

 equal to half the length of the scape; a prominent curved carina 

 extending from below the eyes to the base of antennae; front very 

 coarsely, deeply and confluently punctate : vertex and genae coarsely 

 and confluently punctate but not so deeply as the front; longitudi- 

 nal carina of genae distinct and sharp : distance between the hind
