from Embudo, Xew }[exico. 513 



face smootlicr and more shiny, but still granular, with rather 

 sparse punctures ; front rouii^hened. Pubescence of thorax 

 dense, orani^e beneath, t'ox-red above ; a lari^e part of meso- 

 thorax and middle of scutclhnn practically nude, as also the 

 metathoracic enclosure, which is dull and not bounded by any 

 raised line. ]\Iesothorax regularly and strongly granular ; 

 scutellum granular, with shallow punctures. Toguhe trans- 

 parent amber-colour. Anterior wings rather pale fuliginous, 

 broadly darker on outer margin, largely hyaline in median 

 and anal cells ; nervures and stigma piceous, stigma rather 

 small ; hind wings hyaline, with the basal third fuliginous. 

 Legs black, with orange hairs. Abdomen black, micro- 

 scopically tessellate, with very sparse inconspicuous shallow 

 punctures ; sides of first segment, broad submarginal bands 

 on segments 2 to 4 (on 2 interrupted medially), the fifth 

 segment, and the apex all clothed with foxy-red hair; in 

 addition, the second and third segments have very narrow 

 apical hair-bands, contrasting with the rufous broad hair- 

 bands above them. Tibial spurs rufous. 



llah. Embudo, at flowers of Bigelovia, Sept. 25 to 27. 

 Nine specimens. 



Tiiis fine species seems to be allied to A. ohscuripennis^ 

 Smith, from Georgia, but it differs from that in the entirely 

 black clypcus, the colour of the legs, and the distinct fascia3 

 of the abdomen. 



Mutillidae. 



Ephuta calif urmca (Rad.), var. euchroa, n. var. 



? . — Similar to the typical form, but the bright pubes- 

 cence (on dorsal surfaces of head, thorax, and abdomen) all 

 of a beautiful deep crimson or carmine, instead of ferruginous 

 or golden ochraceous. 



Ilab. Embudo, one on sand by the river, Sept. 25. Also 

 one collected by Prof. H. F. Wickham at Coolidge, N. M., 

 some years ago. 



I have seen exactly the same colour of pubescence in an 

 example of Ephuta pacifica (Cresson), collected by Mr. Wick- 

 ham in California. This insect bears a great resemblance 

 to our variety, but is readily distinguished by its considerably 

 larger head. 



The generic name Ephuta has priority over Sphcerophthalma, 

 as has been indicated by Mr. Fox.
