4.5 mm., surface shallowly and finely reticulate, shining, yellowish 
brown (in alcohol), with numerous minute sensilla. Clypeofrontal 
suture well marked; frontal sutures (“arms of epicranial suture” 
auct.), very fine, almost obliterated, anterior half convex toward the 
outside, posterior half straight to concave; epicranial suture (“stem 
of epicranial suture” auct.), about one-third the length of one of the 
frontal sutures, anteriorly with a small, shghtly impressed, brownish 
enlargement. Dorsoexterior region (DF, fig. 20) of mandible with- 
out punctures or small hairs; dorsomolar region (DM) with an 
oblique series of about seven setae on the right mandible and about 
half as many on the left mandible; a patch of several basolateral 
setae present. Epipharynx (CR, fig. 18) with two large and about 
seven small sensilla in the space in front of crepis; about six sensilla 
behind inner end of dexiotorma (DX). Raster (fig. 14) with all 
the tegillar setae of approximately the same length and strength. 
LARVAE OF CNEMARACHIS NEGLECTA (BLANCHARD), C. SUTURALIS 
(CHEVROLAT), C. DISSIMILIS (CHEVROLAT), AND C. PORTORI- 
CENSIS (SMYTH) (?) 
In addition to the larvae of Qnemarachis vandinei (Smyth), the 
U. S. National Museum possesses a single or a few larvae of the fol- 
lowing West Indian species of Cnemarachis: 
1. C. neglecta (Blanchard), from Santa Rita, Puerto Rico, col- 
lected January 19, 1911, by D. L. Van Dine. 
2. C. suturalis (Chevrolat), attacking roots of sugarcane, Baragua, 
Cuba; collected April 8, 1931, by H. K. Plank, reared; adult deter- 
mined by Dr. E. A. Chapin. 
3. CO. dissimilis (Chevrolat), in soil, Baragua, Cuba, collected by 
Stahl, cast skin of mature larvae associated with the reared adult; 
adult determined by Dr. E. A. Chapin. 
4. C. portoricensis (Smyth) (?): (a) in soil near banana roots, 
Arecibo, Puerto Rico, November 26, 1935, Faxon coll., marked “San 
Juan 5945”; (6) in soil around Caguas, Puerto Rico; (c) in banana 
roots, Mayagiiez, Puerto Rico, June 27, 1935, marked “San Juan 
6061.” 
The larva of C. neglecta (Blanchard) is so similar to that of @. 
vandinei (Smyth) that I have been unable to separate them. The 
same is also the case with the larval forms tentatively determined 
in the Museum collection as C. portoricensis (Smyth). It should be 
noted particularly that the appearance of the raster is identical in 
the larvae of these species. 
The larvae of C. suturalis (Chevrolat) and C. dissimilis (Chevro- 
lat) are inseparable but both differ from @. vandinei, C. neglecta, and 
C. portoricensis (%) in having a group of about eight very strong,
