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

 ped with whitish, the other trochanters pale yellow basallj' marked with 

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

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

 let is only J as long as the rhomb. Length (^ .52 inch. Front wing (^ 

 .35 inch. 



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

 claws, this d" could scarcely be referred to [^scutellaris'\ $ 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.

 DiflFers from [^scuiellarts, Cress.] cT only as follows: — i. 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 antennae 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 carinas are 

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

 the joints are proportioned and sculptured nearly as in \tegularis, Cress.], 

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

 are rufous. Except the basal 4 of i, 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 h. as long as the rhomb. Length ^ .35 inch. Front wing 

 S .25 inch.
