This differs from CceJioxys in the greafly developed outer 

 nrea of the galea ; but this is only a specific character, as the 

 following cases show : — 



M. fords. — Decussated area much the broadest, plain area 



very small. 

 M.Jidelis. — Plain area even more reduced. 

 M. piignata. — Plain area on apical half a little larger than 



the decussated, but it is narrow below. 

 JA manifesta. — Plain area larger than the decussated. 

 M. exilis. — Plain area very narrow. (This species is 



peculiar for the maxillary palpi, whicli are covered 



with long bristles, and the third joint is remarkably 



long.) 

 M. cleomis. — Plain area almost as large as the decussated. 



Phileremulus nanus, Ckll. 



Labial palpi. — 1 long, a little longer than 2 + 3 + 4 ; 2 

 short, not very much longer than 3 ; 3 and 4 similar in cha- 

 racter to 2. (Compare with nomada.) 



Tongue. — Very long and slender, about twice as long as 

 labial palpi. The tongue resembles that of AJlodape. 



Maxillary palpi 5-jointed ; 1 broad and flattened; 2 long, 

 cylindrical ; 3 broader than 2 or 4 ; 5 somewhat constricted at 

 middle. Measurements of joints in /i : — (1) 15, (2) 6(5, 

 (3) 27, (4) 24, (5; m. 



Galea. — JSlender, falciform, sepia-colour, with the inner 

 margin of apical half colouiless ; the sepia portion with 

 minute hyaline dots ; inner margin with few minute hairs. 



Neolarra pruinosa, Ashra. 



Description from material taken at Mesilla Park, N. M., 

 May 7, on flowers of Dithyrea Wislizenii. 



Labial 2^alpi' — 2 longer than in Fhileremulus and nearly 

 twice as long as 3. 



Maxillary jja/pi G-jointed ; 4 broad at end ; 6 very slender, 

 only hah" as broad as 5. Measurements in p,: — (1) 24, 

 (2) 6i), (3) 36, (4) 45, (5) 57, (0) GU. 



Neolarra and Lfnleremxdus agree nearly with Allodape in 

 the mouth-parts. Smith figures, but does not count, a first 

 joint in the maxillary palpus of Allodape similar to that of 

 Fhileremulus) on tiie otiier hand, he appears to count the 

 long teiminal joint as two. Ihe habits of Allodape seem to 

 resemble those of l^hilereinulua.
