— 62 — 



stipes with an oblique suture (as in albohirtum) which 

 continues ventrad and distad to the galea and lacinea. 

 Joints of labial palpus only about twice longer than wide 

 or not quite that, joint, somewhat longer than wide. 



Latero-cervical shield acute at . ventral end not 

 blunt as in albohirtum) and more dorsad, its ventral 

 tip just reaching a little ventrad of middle of peri- 

 tremes (in albohirtum its ventral tip extends a short 

 distance ventrad of ventral end of peritremes). This 

 shield bears marginal clothing caudo-dorsad and a 

 few cephalad. Cervix armed with several rows of 

 very minute blackish teeth. 



Tarsi a little more slender. 



Clothing of cephalic and lateral margins of labrum 

 short and uniform like human eye Cashes. The thorax 

 and abdomen bear in the incisions between the folds 

 a line of minute teeth like those on the cervix; this 

 row is usually paired. The teeth like setae in rows 

 on segments 2 — 6 of abdomen are very much larger 

 than the minute setae between the folds and on cervix 

 and a few of the setae stand out (long and slender) 

 above the others (first nine body segments). 



Venter of thorax also with the row of minute teeth 

 in the incisions or near them, mostly irregularly 

 paired rows. 



Venter of Segment 9 of abdomen with a paired 

 row of moderate setae across a little cephalad of center ; 

 before apex with numerous stout, rather short setae 

 which become decidedly longer around the apex like 

 a fringe, none of these setae are more than feebly bent 

 over at tip; no median path on venter of anal segment. 

 Dorsum of segment 9 of abdomen before apex den- 

 sely clothed with setae which are slenderer and longer 

 than those on the venter (except the apical fringe). 



Greatest length when extended, 43.0 mm; greatest 

 Avidth (base of abdomen), 10 mm. Greatest width 

 of head, 6.75 mm; length in natural position (dorsum 

 to dorsum), 17 mm. Thickness, 7.5 mm. 

 Stage II. 



The same. Vestigial thoracic stigmata obsolete. 

 Clypeus with an additional minute seta some distance 

 on each side from meson in a line with the marginal 

 bristle laterad (a small puncture indicates its presence 

 in III). 



Joint 3 of antenna a little the shortest. 

 i'' 1 ' Distal third of mandible black. Joint 2 of ma- 

 xillary palpus a little shorter than 4. Teeth of cervix 

 very minute but visible with a lens, also the minute 

 intersegmental setae. 



Greatest width when extended, 24 mm; greatest 

 width ; 4.75 mm, base of anal segment, length in natural 

 position, 10.75 mm; greatest width of head, 3.5 mm. 

 Thickness, 4.7 mm. 



Stage I. 



The same. Peritremes very pale yellow, also the 

 latero-cervical shield, the legs white. Spiracles about 

 as in Stage I of albohirtum. Setae of cervix very mi- 

 nute, pale, just visible with a lens. Distal edge of 

 mandible black. Antennae pale, joint 4 distinctly 

 longer than 3, the latter shorter than 1. Bristle near 

 lateral apex of joint 3 of maxillary palpus long and 

 slender, extending beyond middle of joint 4 which 

 is somewhat longer than 2. 



Greatest length when extended 10 mm ; greatest 

 width, 1.80 mm, base of anal segment; length in 

 natural position, 4.7 mm. Greatest width of head 

 2.15 mm. Thickness, 1.65 mm. January, February, 

 March. 



The Egg. 



Creamy white. Chorion soft. Sculpture absent, 

 the micropyle inconspicuous, the surface with a faint 

 pearly lustre. Shape ovate. Length, 3 mm. Greatest 

 width, 2.35 mm. Longer before hatching. Deposited 

 in the soil. December, January. 

 The Pupa. 



Form ovate, convex above, flat ventrad, narrower 

 caudad and in general resembling Lepidiota albohirtum 

 Waterhouse. Length, variable, about 27.5 mm. Gre- 

 atest width (at segment 2 of abdomen), 12.5mm. 

 Body unarmed save at apex where there is a very 

 short reddish golden fuzzy pubescence and a pow- 

 dery golden pubescence is present over the body best 

 seen at an angle and at extremities and edges. No 

 noticable sculpture but all surface microscopically 

 sheened. 



Color changing from white to reddish brown. 

 As in Lepidiota albohirtum. Antennal and mandi- 

 bular exfoliation separated narrowly from the eyes, 

 at apex simple but broadly transversely widened 

 and truncate and against the cephalic tibia distad 

 of the latter's middle. Apex of elytron extending 

 a short distance beneath middle tibia and a little 

 beyond tip of it; they reach segment 4 of abdomen 

 or thereabouts. Lateral margin of elytron only faintly 

 rimmed, not transversely wrinkled. 



Dorsal view. Head just visible, also extreme tips 

 of all knees. Apex upturned. 



Prothorax with the margins only faintly rimmed, 

 the median suture a faint, narrow line without „cross- 

 stitches". Apex of mesothorax simple, acute, its 

 median suture like that of the pronotum. Metathorax 

 intermediate in greatest length of the thoracic regions. 



Abdomen widest at segment 2; segments 2 — 6 the 

 same as in albohirtum but the sides are obtuse, rounded 

 not sharp and acute; each one of these segments 

 at meson is projected cephalad a short distance, 

 cephalic margin; segment 9 is longest, then 8, then 7. 

 Ventral segments 2 — 6 are about the same but the 

 cephalic margins are straight. Segment 9 dorsad 

 with an obtuse median furrow whose margins are 

 not distinct carinae. Segments 7 — 9 dorsad practi- 

 cally immargined, ventrad distinctly margined, the 

 imargins thick, joining at apex like two lobes which 

 nclose the protuberant anus. No cremastral armature. 

 Ventral segments & — 6 without a median scar. 



Ventral view. The maxillary palpi are more erected 

 and the third indicated joint is quadrate. Labial 

 palpi with three divisions. The middle tarsus is upon 

 the cephalo-mesal corner of the elytron and is free. 

 Caudal tarsi at tip approximate, above segment 7 

 of abdomen and parallel with the venter. 



Formed much as in albohirtum but generally wr- 

 apped within the larval cast which remains rigid and 

 enfolds the pupa like an unfastened cloak. Formed 

 in the spring (late October, November).
