Maxillary stridulatory teeth moderately long, numbering 9-13; propleg- 
mata about 10; heli about 7. [Pali in two medianly meeting, posteriorly 
strongly diverging series, and anterior to these with about 12 tegillar 
setae on each side and nearer the anterior margin of the segment with 
very long, thin, straight setae.]

pariae without sensilla in vandinei, sensilla in front of crepis number- 
ing about 10 in vandinei, or more in other species.] (Figs. 18, 14, 19,

8 (6). Zygum fairly distinct; a thin, somewhat crescent-shaped sclerotization 
present in front of chaetoparia on each side of zygum; number of heli 
about 7; plegmatium broadly elliptical; many sensilla in front of 
crepis (about 35 in C. smithi, about 15 in C. apicalis) ; teges with a 
median group of 9 to 15 setae stronger than the rest. [Right chae- 
toparia with many sensilla, left with comparatively few;-distal article 
of antenna elongate, spindle shaped; anterior margin of frons with 
long and moderately long setae; disk of frons with two long setae on 
each side.] (Figs. 15, 16.) 
Clemora smithi (Arrow) (Jamaica, Barbados) 
C. apicalis (Blanchard) (7?) (Haiti) 
Zygum vestigial or absent; no sclerotization in front of chaetopariae; 
number of heli about 15; plegmatium narrow; two sensilla in front 
of erepis; setae of teges alike in shape and strength. [Chaetopariae 
without sensilla; distal article on antenna short and thick; anterior 
margin of frons with numerous moderately long or short setae; disk 
of frons with numerous moderately long setae.] (Figs. 4, 6, 7.) 
Anoxia pilosa Fabricius (Hungary)

9 (2). Pali arranged in an irregular, rather short row on each side, and a 
few not paired pali often present in the longitudinal middle line of 
septula; number of heli about 15. [Zygum very weak; epizygum 
vestigial, not connected with zygum; plegmatium narrow; sensilla 
are identical with those given for melolontha. Neither of them mentions any characters 
pertaining to the epipharynx. It is possible therefore that the character combination as 
given here for melolontha might not apply in toto to all species of the genus Melolontha.
