214 NORTH AMERICAN MUTILLIDAE 



The coloration of the female is not constant. 



Taking all things into consideration this form seems to be the 

 most suitable to identify as Say's species. In all respects except 

 the size of their ocelli, the species sayi Blake and rnfosignata 

 appear to be alike. 



Habitat. — Males. New York: Yaphank, Long Island, 22 September, 1911 

 and 11 October, 1913, (G. P. Engelhardt). Virginia: Falls Church, 7 and 12 

 August, (N. Banks). Illinois: Lake Forest, 22 August, 1906, (J. G. Need- 

 ham), [Cornell Univ.]. Indiana and Missouri (Original records by Say). 

 Texas: 2 specimens, [Amer. Ent. Soc.]. Colorado: 1 specimen, [Amer. Ent. 

 Soc.]. Montana: 1 specimen, [Amer. Ent. Soc.]. 



Females. New York: Yaphank, Long Island, 22 and 24 September, 1911, 

 (G. P. Engelhardt); Central Park, 17 April, 1912, (G. P. Engelhardt). New 

 Jersey. Virginia: Falls Church, 18 April, 17 May, 2, 4, 11, 27 August, 

 3, 24 September; Great Falls, 28 June, 12 September; Glencarlyn, 26 Septem- 

 ber, (N. Banks), [N. Banks]. Georgia: 1 specimen, [Amer. Ent. Soc.].

 No. 113.2]. 



Mutilla (TimuUa) sayi Blake 



1871. Mutilla sayi Blake, Trans. Amer. Ent. Soc, 3 :29, cf • 



o^. Transverse diameter of the posterior ocelli .32 mm., their 

 distance from the eyes .37 mm., from each other .58 mm., from 

 the front ocellus .22 mm. 



This species agrees in all structural characteristics, so far as 

 I have observed, except the size of the ocelli with hexagona. The 

 records given by Fox "Montana" and "Colorado" are based on 

 specimens of hexagona. It would be no cause for surprise if 

 future series would reveal the identit}^ of the two. 



Habitat. — Missouri: Columbia, S cT, 13, 21, 22, 29 July, 2 September, 

 1905, [Univ. Mo., Cornell Univ.]. Texas: 3 d", [Amer. Ent. Soc.].
