— 14 — 



twice the length of the cephalic one, the hind tarsus 

 subequal to the hind femur or somewhat longer. 



Abdomen with segment 9 somewhat longer in 

 proportion to the others. 



Clothing the same but setae, around edge of 

 labrum all subequal and like eyelasnes; the setae 

 in the cross row near caudal margin of labrum are 

 minute; there are only two unequal setae between 

 mandibles and antennae. Abdominal and thoracic 

 clothing about the same but the setae are proportio- 

 nally smaller. The path on anal segment ventrad is 

 slenderer, about five and a half times longer than 

 wide and the number of delimiting teeth are from 

 24—26. 



Stadium I. 



Color the same; as in stage II; dorsal ridge of 

 mandible not so black proximad. Three white spots 

 on distal antennal joint. 



Stigmata absent, blind; peritremes small, round 

 to oval, those of the thorax long, elliptical, closed 

 but the opening indicated in the same positions, the 

 surface densely scaly; peritremes of the caudal three 

 or four pairs partly open, the whole resembling a 

 depula or hollowed blastula of an embryo. 



Greatest length, 18.0 mm; greatest width, 

 3.30 mm; length in natural position, 6 mm; thick- 

 ness, 3.75 mm; greatest width of head, 2.90 mm. 



Head the same ; labrum somewhat smoother, the 

 clypeus smooth or nearly. Joint 2 of antenna only 

 somewhat longer than 2, 4 a little conical at tip. 

 Appendix about a sixth the length of joint 4. Joint 

 2 about two and a half times longer than wide at 

 apex. Under low power microscope, clypeus and 

 cephalic part of epicranial sclerite shagreened. Man- 

 dibles the same but the clothing on both mandibles 

 at base (mesad, really) of middle of retinaculum is 

 not reduced in size. 



Shieds of legs not colored, not differentiated. 

 Tibiae subequal. Abdomen somewhat over thrice 

 the length of the thorax. 



Clothing as in II but the row across near 

 caudal- margin of labrum absent ; only two long setae 

 along cephalic margin of epicranial sclerite, one on 

 each side of the meson. 



The Pupa. 



Form ovate, convex above, flat below, narrower 

 caudad. Length variable; 33.0 mm average. Greatest 

 width (across caudal thorax), 15.0 mm. Body naked, 

 without sculpture but in dried pupae the dorsum 

 of segment 7 is longitudinally striate probably due to 

 transverse wrinkling. 



Color white upon pupation, gradually changing 

 to pale yellowish brown and just before pupation 

 black. Antennae in ventral view not visible in younger 

 pupae except as a broad exfoliation between the 

 eye and the maxillary palpus; this incloses both the 

 antennae and mandible; in pupae near the change, 

 the antennae are more or less clearly delimited for 

 their entire length along the ventrolateral edge of 

 this part which is separated rather broadly from the 

 eye, extends beyond the latter but does not reach 

 the cephalic tibia ; its apex bears more or less distinct, 



longitudinal sulci and it narrows at base. The arti- 

 culation of antennae is not distinct. 



Elytra rather large, curving over the side of 

 the thorax and extending alongside the middle tibia 

 and tarsus but not reaching tip of latter; their apex 

 is blunt, conspicuous in ventral aspect. They reach 

 the third abdominal segment. Their lateral margins 

 are rimmed and the surface bears transverse wrinkles, 

 not visible in lateral aspect; in dorsal aspect their 

 base is conspicuous. The tips of the wings (ventral 

 aspect) project a short distance from the disto- 

 caudal end of the elytra. 



Stigmata visible on segments 2 — 6 of abdomen 

 only, a little dorsad of the midlateral line; rounded- 

 oval, open; closed and subobsolete on 5 and 6; in- 

 dicated on the dorsal aspect of the lateral rim of 

 segments 7 and 8. Visible obliquely in dorsal aspect. 



Clothing absent. 



Dorsal view. Upper part of head visible, 

 also the caudal knees a little, just caudad of elytra 

 and ventrad of an edge of the wing which shows 

 distinctly. The other knees are barely visible together 

 between the elytra and the pro thorax. 



Prothorax wider than long (dorsad), its lateral 

 margins with distinct rims, margined cephalad and 

 caudad (more distinctly) and divided by a median 

 suture. The dorsal surface is convex and glabrous, 

 transversely wrinkled cephalo-laterad. 



MesothoBax triangular, about half the width of 

 the pronotum, with the median suture, its apex 

 raised and terminating in a pair of swollen lobes not 

 deeply divided. The median suture bears along its 

 length cross-striae which are distinctly longer than 

 those on pronotum and metathorax. The striae 

 also occur frequently in the corners of all thoracic 

 segments. Apex of triangle caudad. 



Metathorax nearly as large as the prothorax but 

 distinctly less wide, its cephalic margins obliqued 

 cephalo-laterad; also its lateral margin obliqued 

 caudo-laterad, curved, the caudal margin nearly 

 straight. Thorax sloping distad to apex, then curved 

 dorsad. 



Abdomen widest at segments 2 and 3, segment 1 

 flat but with a transverse, emarginate ridge distad 

 of middle; segments 2 — 6 very strongly ridged trans- 

 versely, the following segments flat. On segment 

 2 — 6 the strong, erect ridges dorsal are linear but 

 are abruptly folded over on to the venter ventrad 

 and thus flattened. Segments 7 — 9 rimmed laterad, 

 9 with two median carinae somewhat separated, ven- 

 trad the anus distinctly protuberant. Cremaster a 

 fork consisting of a pair of short, tumid, diverging 

 projections armed at tip with a short, stout thorn 

 like spine. Ventrad segments, and 2 hidden, 3 — 6 

 each with a central trans verse-crescentic scar. 



Ventral view. The head has a cephalic 

 aspect. The maxillary palpi project stiffly from 

 between mandibles and maxillae as rather long stout, 

 blunt rods sometimes with the apex lying upon the 

 base of cephalic tarsus but usually above it. They 

 usually bear transverse incisions and the segmen- 

 tation is rudely indicated as being of four pieces of 

 which the third is wider than long (not always dis-
