the specimens before me make it necessary to restore the species. 

 Cresson's type of speciosa, a female, came from Colorado and his type 

 oifonnosa from Texas. Both Handlirsch's and Cameron's specimens 

 were all from Texas, and the descriptions indicate that they belong to 

 Cresson's /orwosa. I have before me females from Colorado, Texas, 

 and Kansas and males from New Mexico and Texas. The males 

 from these two localities are structurally distinct as well as differently 

 maculated, and those from New Mexico are so nearly like the female 

 from Colorado in color and general appearance as to warrant, in my 

 opinion, the assumption that they are sexes of the same species. 

 Aside from the fact that the males in question are positively distinct, 

 the color of the females and the pattern of their abdominal fasciae are 

 sufficiently unlike to justif}^ the contention that they belong to dif- 

 ferent species. 



Habitat. — Texas, Kansas. 



Number of specimens examined — Males, 5; females, 4.

Male. — Black: Labrum, mandibles except apices, clypeus except 

 narrow basal border, lower part of frons, irregular V-shaped spot 

 inclosing anterior ocellus, anterior orbits irregularly notched and 

 reduced to a very narrow line above, comparatively broad posterior 

 orbits extended for some distance on the posterior border of the ver- 

 tex, pro thorax except a median anterior dorsal spot, and a dusky spot 

 anterior to tubercles, tegulae, broad lateral lines and a broken U- 

 shaped discal spot on scutum, broad fascia on scutellum narrower 

 medially, metanotum, broad curved fascia on dorsum of median 

 segment extended in a pair of triangular points on its posterior sur- 

 face, lateral angles including much of the posterior surface and all the 

 sides of the median segment, metapleurae, mesopleurae, and mesos- 

 ternum except a pair of large black spots in front of the middle coxae, 

 broad fasciae on tergites 1-6, the first roundly or somewhat trian- 

 gularly emarginate on its anterior middle and slightly biemarginate 

 on its posterior border, second with anterior medial emargination 

 somewhat extended at its posterior lateral angles and notched with 

 yellow on the middle of its posterior border; the remaining fasciae 

 with four anterior emarginations, the middle pair somewhat the 

 larger and deeper, apex of ultimate tergite, broad continuous fasciae 

 on all sternites, coxae except basal spot below, trochanters except 

 more or less black above, femora except broad stripe on anterior pair 

 above, tibiae, and tarsi, hriglit lemon yellow. 



The ultimate segment of the antennae is curved and segments 5-1 1 

 are faintly carinate on the posterior surface. The middle femora are 

 slightly angulated below near the base, and from this point to the 

 apex extends a row of short stout spines. The middle metatarsi are
