In the hind legs the coxae and the basal trochanters are black lightly tip- 

 ped with whitish, the other trochanters pale yellow basally marked with 

 black, and the rest of the leg black except that the knees and the basal | 

 of the tibia; are pale yellow; claws simple. 8. The peduncle of the areo- 

 let is only $ as long as the rhomb. Length tf .52 inch. Front wing o* 

 •35 inch. 



One % ; ? unknown to me. Neglecting the difference in the 

 claws, this c? could scarcely be referred to \_scutellaris\ 2 on ac- 

 count of the wide, rufous band on the abdomen, which, so far as 

 I know, is not a sexual character in this family.

 Differs from [Scutellaria, Cress.] o* only as follows : — 1. The white mark- 

 ings of the latter, whether on the body or the legs, become here pale yel- 

 low or are obsolete. 2. The entire face, except the lateral fovea: at the 

 tip, and the entire clypeus, are pale yellow, and the orbits are pale yellow 

 up to the top of the vertex, but are interrupted opposite the ocelli by a 

 space rather longer than they are wide, so as to leave a pale yellow dot 

 on the vertex. 3. The antenna; are full as long as the body, brown-black 

 above and below, with the 1st and 2d joints pale yellow beneath. 4. The 

 pale spot before the front wing is prolonged in a slender, pointed line 

 along the lower edge of the humeral suture nearly to its tip, and above 

 the humeral suture there is only a small elongate spot opposite the tip of 

 the preceding. The tegulae and a short line under the wing, the anterior 

 border of the collare, and the entire mesosternum halfway up its pleura, 

 with the exception of its declivous surface in front and a large geminate 

 black spot behind, are also pale yellow. The rest of the thorax is black. 

 5. The metathorax is entirely opaque, and the longitudinal carina; are 

 entirely unrepresented. 6. The abdomen is regularly elongate-oval, and 

 the joints are proportioned and sculptured nearly as in {tegulctris, Cress.], 

 but the terminal \ of 1 and the whole of 2-8, except an obfuscation on 8, 

 are rufous. Except the basal \ of 1, the whole venter is dull pale rufous. 

 7 The 4 front legs are pale rufous, with all their coxae and trochanters 

 pale yellow. The hind legs are pale rufous, with the terminal i of their 

 coxae and the terminal trochanters pale yellow ; claws simple. 8. The 

 stigma is black, basally tinged with rufous; and the peduncle of the areo- 

 let is scarcely £ as long as the rhomb. Length 0* -35 inch. Front wing 

 <5 .25 inch.
