CLASSIFICATION OF THE DERMESTIBAE 7 



3. Caudal brush of long setae present (fig. 2, J and J) ; antennae (fig. 



2, L) long; body elongate, sclerotized dorsally and ven- 



trally ,, Attageninae, pp. 8-9. 



Caudal brush absent; antenna (fig. 2, M and N) short; body oval or 

 oblong, sclerotized dorsally, membranous ventrally 4 



4. Each tergite (fig. 3, K) with a comblike series of coarse, spinulate, 



clavate setae posteriorly ; setae short ; 3 large subequal ocelli on each 



side of head Thylodriinae {Thijlodrias contractus Mots.), p. 10. 



Tergites (fig. 3, J) without comblike series of clavate setae; setae very 

 long, arising from clear areas of the tergites; pigmentation pattern 

 at midline broadly sagittate ; 6 ocelli on each side of head, in 2 groups 

 of 3 each Trinodinae (Aspectus hispidus (Melsh.)), p. 9. 



5. Body setae (fig. 3, G) brownish yellow to yellowish brown, faintly 



ridged ; ninth tergite (fig. 2, I) at least one-half as long as eighth, 

 gradually arched longitudinally ; setae of caudal brush numerous, 



arising at random on the ninth tergite Attagenus, p. 9. 



Body setae (fig. 3, H) except caudal brush and sometimes on head, 

 brownish black to jet black, strongly ridged; ninth tergite (fig. 2, J) 

 not more than one-third as long as eighth, sharply arched longitudi- 

 nally ; setae of caudal brush about 20, arising in 2 compact groups of 

 about 10 setae each from the almost perpendicular posterior area of 

 the segment Novelsis, p. 9. 



6. Distal sensory papillae of epipharynx (figs. 4, F, and 5, C) in one or 



more sharply defined, compact groups ; second antennal segment sub- 

 equal to first or longer (fig. 2, P), rarely twice as long as first__ 9 



Distal sensory papillae of epipharynx (fig. 5, E and F) loosely grouped, 

 distinctly and widely separated, large to minute; second antennal 

 segment (fig. 2, 0, Q. R, and S) never less than twice as long as first 7 



7. Distal sensory papillae (fig. 5, F) near distal margin of epipharynx, 



large, typically 6, in 2 longitudinal series of 3 each Ctesias (C. serra 



(F.)),pp. 12-13. 

 Distal sensory papillae (figs. 4, E, and 5, E) nearer middle of epiphar- 

 ynx, medium to minute, in a faintly defined, fusiform area 8 



8. Middle setal series of labro-epipharyngeal margin (fig. 5, E) with broad 



and slender setae, typically with 2 broad inner setae and 2 slender 

 outer setae (proximal sensory cups of epipharynx about 



12) Anthrenus, p. 12. 



Middle setal series on labro-epipharyngeal margin (fig. 4, E) with 

 broad setae only, typically 4 (proximal sensory cups of epipharynx 

 about 9) Perimegatoma, p. 11. 



9. Frons with a single medio-anterior tubercle ; distal sensory papillae of 



epipharynx typically in 2 or more sharply defined, compact groups 13 



Frons without tubercle; distal sensory papillae of epipharynx in a 

 single, sharply defined, compact group 10 



10. Middle setal series of labro-epipharyngeal margin (fig. 5, A and B) 



with slender setae only, sometimes lacking 12 



Middle setal series otherwise (fig. 4, F) 11 



11. Epipharynx (fig. 4, F), with proximal transverse series of 10 to 20 



sensory cups Trogoderma, p. 11. 



Epipharynx with proximal transverse series of about 7 to 8, never more 



than 9, sensory cups unnamed genus based on Perimegatoma ves- 



pulae Milliron, p. 11. 



12. Epipharyngeal rods (fig. 5, A) slender, curved; epipharynx with prox- 



imal transverse series of 8, or less, sensory cups (tergites at midline 

 with very long, spinulate setae in addition to shorter, normal, spin- 

 ulate setae and h&stisetae) —Thaumaglossa (T. americana Jayne), 

 p. 11. 

 Epipharyngeal rods (fig. 5, B) broad; epipharynx with proximal 

 transverse series of more than S, usually 13, sensory cups (tergites 

 at midline normal) Cnjptorliopalum (C. duoium Sharp), p. 11. 



13. Epipharynx (fig. 5, C) with proximal transverse series of 12 or less, 



usually 8, sensory cups (lateral setae of labro-epipharyngeal margin 



about 8) GloUcornis (G. sp., probably fulvipes Guerin), pp. 11-12. 



Epipharynx (fig. 5, D) with proximal transverse series of more than 12, 

 usually 16, sensory cups (lateral setae of labro-epipharyngeal margin 

 about 13) Lalrocerus (L. simplex Sharp), p. 12.
