63. Miitilla cliiroii Blake. 



Mutilla chiron Blake, Tr. Am. Ent. Soc, iv. 72. % , 1872. 

 Sphserophthalma chiron Blake, ibid, xiii, 220, % , 1886. 



Texas. It is doubtful if the specimens I have referred to chiron 

 really represent that species. These I am inclined to regard as a 

 variety of Ursula, having the thoracic pubescence black. They 

 agree with Blake's description of chiron, except that no mention is 

 made of the pale maculation of dorsal .segment 2, and the third 

 subraarginal is much less distinct than one would imagine that of 

 chiron, judging from the description. The latter might also be 

 applied to the % zelaya. Unfortunately the types of chiron seem 

 to be absent from the material on which Blake's work is based. 



64. iVIiitilla zelaya Blake. 



Mutilla zelni/ii Blake, ibid, iii, 234, % , 1871. 

 Sphserophthalma zelaya Blake, ibid, xiii. 211, % , 1886. 



Texas; New Mexico: Albuquerque, August (Snow). The 9 

 may be described as follows: — Black throughout, with black pube.s- 

 cence, except on dorsals 2-5, which have long fulvous pubescence 

 extending a little onto the ventral segments ; head with strong 

 punctures ; thorax elongate, broadest anteriorly, scarcely pyriform, 

 above coarsely reticulate, more distinctly posteriorly ; first segment 

 above coarsely pitted, the ventral carina strongly bidendate in con- 

 sequence of a deep mesial emargination. Length 10 mm. 



65. Mutilla castor Blake. 



3Iiitilla (SphierophthaJma) cantor Blake, ibid, iii, 237, % , 1871. 

 Sphserophthalma castor Blake, ibid, xiii, 227, % , 1886. 



Occurs from Illinois to Texas and Oklahoma Territory. Also in 

 Florida. The color of the first two segments varies from entirely 

 red with paler spots on segment 2 to black, except the pale spots 

 mentioned. This species will, no doubt, be found under the name 

 fenestrata Lep. in some collections. 



66. Mutilla Lepeletierii Fox (n. ii. for feuestrafa Lep. iion King). 

 MiUilla fenestrata Lepeletier, de St. Fargeau, Hym., iii, 627. %, 1845. 

 Mutilla (Sphserophthalma) fenextrata Blake, 1. c, iii, 238, % , 1871. 

 Sphserophthalma fenestrata Blake, ibid, xiii, 228, %, 1886. 



Pennsylvania (St. Fargeau) ; New Jer.sey : Ocean County (J. B. 

 Smith). It is somewhat difficult to decide from St. Fargeau' s 

 description whether Blake's castor or the specimens before me are 

 fenestrata. Fargeau does not mention paler spots on second seg-
