point, namely, that there is but one spine at tip of abdomen. It 

 will be seen from this that Blake had gathered representatives of 

 two genera under Photopsis, and the question to be decided is to 

 which belongs the name Photopsis. 



The fact that Blake states in the description of Photopsis that 

 the apex of S is armed with two spines, proves, in my opinion, 

 that the name really belongs to those rather coarsely sculptured 

 species with two spurred tibise, of which mendica, danaus, iapajos 

 and nebulosus are examples, and which have this character, and, 

 further, while no type of the genus has been mentioned by Blake, 

 and the value of such evidence on that account is somewhat 

 lessened, yet he places as the first species in his list P. mendica — 

 a true type of the coarsely sculptured, two spined species. Further 

 study on these species indicates that they belong to the genus 

 SphcEvophthalma, not differing from that genus in any respect. 

 Consequently it will be seen from the evidence at hand that Pho- 

 topsis must fall as a synonym of Sphcerophthalma, and the spe- 

 cies which Blake may have meant for that genus, although the evi- 

 dence is to the contrary, should stand as Brachycistis. 



A NEW SPECIES^OF MUTILLiD/E. 



By William J. Fox. 



Sphaerophthalma tonmeyi £ • — Ferruginous. Head from above quad- 

 rate, the posterior angles spinose; beneath, on the cheeks, there is a 

 rather long, stout spine; the head is clothed rather densely with appressed 

 pale golden hair, and in addition has sparse, erect hairs; the thorax with 

 sparse, erect, hairs, and viewed from above appears in shape like a short 

 oblong, the sides of which are a little contracted medially, and possess 

 quite a few small teeth; first abdominal segment uniting evenly with the 

 second, and with silvery pubescence at its apex, which extends on the 

 base of the second segment, this possesses two large, round spots of 

 pubescence of the same color; beyond these spots the segment is casta- 

 neous, and the last segment i^lso of that color; the third to fifth dorsal 

 segments are more or less clothed with silvery pubescence; like the head 

 and thorax, the abdomen is sparsely clothed with erect hairs. Length 

 about 3 mm. 



Resembles minutissima in size and markings, but differs by 

 spinose head. From canadensis, to which it is apparently more 

 closely related, it differs by the spined posterior angles of the 

 head, smaller size, and the markings. The specimens were con- 

 tained in a collection of ants from Tucson, Ariz,, sent for identi- 

 fication by Prof J. W. Toumey, of the University of Arizona, 

 to whom it is dedicated.
