 Soc. Phil, iv., p. 442.) 



Twelve % 9 specimens. (Belfrage ; Boll ; Heiligbrodt.) 



Myzine costata. 



Meria cosiata, Say, Bost. Journ. Nat. Hist, i., p. 361. 

 Two 9 specimens found on Shuniach flowers in August. (Belfrage;

Myzine dubiosa, n. sp. 



9- — Black, shining, clothed with sparse glittering white hairs, head and 

 thorax with large scattered punctures; a broad band immediately above an-

 lum reddish beneath ; large subtriangular spot on each side of prothorax, a 

 short submarginal line behind, large spot on disc of mesothorax, a spot over 

 tegulse, band on scutellum, postscutellum, a spot, indented anterior)}', on each 

 side of mesothorax, a small spot on basal middle, and two spots on pleura, that

One specimen, found on Shumach flowers with the preceding species. 

 (Coll. G. W. Belfrage.) Closely allied to sexcincta 9 > but very much 

 smaller, and with clearer wings.

 lemon-yellow; mandibles except tips and scape beneath ferruginous; a large 

 spot on each side of prothora.x, a large triangular spot on disc of mesothorax, a 

 spot above tegulse, band on scutellum, postscutellum, a large spot acutely in- 

 dented anteriorly on each side of metathorax, and two spots on pleura the
