LARVAE OF SOME WEST INDIAN BEETLES—BOVING 169 
Epipharynx (fig. 13)? with distinct epizygum (/’Z) extending to 
and fused with zygum (Z). Plegmatium (PZ) on each side well 
developed, rather broadly elliptical, consisting of 15 or more some- 
what sinuous plegmata; proplegmatium (PPL) well developed, 
broadly lanceolate, consisting of about 35 fine plaits or proplegmata ; 
chaetopariae (C’) with moderately long setae toward pedium (P) 
and slenderer and shorter ones toward plegmatium, no sensilla inter- 
spersed between the setae, two more or less parallel rows of setae 
between proplegmatium and the epipharyngeal margin; zygum thinly 
sclerotized, six large and several small sensilla in a single, curved, 
transverse row along and behind the entire zygum; heli (#7) in two 
transverse rows with five heli in the anterior and two in the posterior 
row; phobae (PH) present; some sensilla in front of crepis (CF). 
Prothoracic and mesothoracic legs with claw (ungulus) about one- 
third the length of tibiotarsus; somewhat swollen metathoracie leg 
with claw about one-sixth the length of tibiotarsus, with enlarged 
base of claw carrying one stout and one finer seta and with small, 
conical, terminal part of claw about as long as basal part and about 
one-fourth the length of the stout seta. 
Raster (fig. 14)? without septula or pali; tegilla (7’Z) composed 
of well-developed, flat, curved, and terminally hocked setae, either 
all the same length and strength or with a considerable number of 
stronger setae in the sagittal middle region; tegillum (7Z) on right 
and left side meeting, thus forming a continuous patch (teges) occu- 
pying almost the whole of the tenth abdominal venter (7G). 
Spiracles each with a C-shaped respiratory plate almost completely 
surrounding the bulla. 
LARVA OF THE GENOTYPE CNEMARACHIS VANDINEI (SMYTH) 
The material on which the following specific description is based 
is in the U. S. National Museum and consists of: 
(1) Cnemarachis vandinei (Smyth), a full-grown larva and a set 
of larval and pupal skins, associated with the reared adult. Larvae 
collected by H. K. Plank, Puerto Rico, October 8, 1935; marked 
SP ie 4 1616.7; 
(2) Onemarachis vandinei (Smyth), full-grown larva, associated 
with a reared adult determined by Dr. E. A. Chapin; the cast larval 
and pupal skins were not kept; collected and reared by H. K. Plank 
at Mayagiiez, P. R., October 1935; marked “P. R. #1617.” 
Length of mature larva about 50 mm. Cranium (clypeus and 
labrum excluded) broader than long, extreme width 6 mm., length
