 ment with dense, silvery pubescence; legs brownish; abdomen from apex of 

 second segment black, the latter above with two pale yellow spots; head with 

 confluent punctures, the postero-lateral angles obtuse; first joint of flagellum 

 not as long as two following united ; thorax rugose, especially posteriorly ; scu- 

 tellar scale rather prominent; carina of first segment indistinctly bidentate; 

 second dorsal striato-punctate, but sparsely punctured on the space occupied by

 Sphserophthalma mutata Blake, ibid, 241, 9, 1886. 



Occurs from New Jersey (August) to Florida; also in Illinois: 

 Algonquin (Nason), and Colorado. The maculation of second dor- 

 sal is subject to variation, and the size varies from 6 14 mm. The 

 postero lateral angles of the head are always tuberculate, or with a 

 short carina, t)y which character the species may be at once distin- 

 guished.

 ment 2 black, this segment above with two pale spots; first three joints of 

 antennae red, remainder blackish ; tarsi fuscous; head seen from front triangular, 

 squarely cut off behind, the postero-lateral angles acutely produced, punctuation 

 strong and distinct; thorax ovato-pyriform, contracted behind from middle; first 

 abdominal segment with a small tooth medially at sides, the ventral carina biden- 

 tate ; second segment with elongate punctures; pygidium longitudinally striated.

 l^pliserophthalma caneo Blake, ibid, xiii, 241, 9> 1886. 



Texas; Colorado; New Mexico: Las Cruces, September 16th 

 (Cockerell). I can see no differences between caneo and mixtura, 

 except as to the quantity of pubescence on thorax, which is variable.
