Fig. G4. Ptipa of Lophodonta angulosa 



cr, rmliiilcnt^irv irfinastcr. 



outward in the median space, and widely bordered with a pale reddish tawny patch, the lino not 



continned to the iniuT (hinder) edge of the wing. The middle (intradiscal) line very distinctly 



bent outward on the c(t,stal edge, making a large rectangle on the cubital vein, ending, alter 



making a small tooth, on the distiuet reddish brown tuft on the hinder edge oftlie wing. Within 



the costal i)ortion of this line is a small white i)atch, anil a very large while jiatcli on the outside 



extending from the ape.x of the angle in the median space to the costa. 



Extradiscal line wavy, forming about eight fine teeth, reddish brown, edged externally with 



white, the line itself nearly straight, not wavy nor very obliipie (much less sinuous than in J^. 



/crnir/iiua), and on e.ich sid(; of the costal end the wing is more or 

 less marked with white. The space between tbcse two lines does 

 not differ in shade from the ground color of the wing (while in L. 

 fcrrudint'd the space forms a distinct broad reddish brown band). 

 A very faint submarginal difiuse line composed of very obscure 

 dark colored luuules. Fringe of the same hue as the wings, with 

 linear white marks at the ei\d of the venules. 



Hind wings and abdomen pale soft Hesh whitish, the costal 

 edge broadly margined with mouse color, interrupted by a trans- 

 verse broad costal band, and another at the ajjcx, not reaching 

 inward beyond the second subcostal venule. 



Beneath, both wings uniformly whitish, the costal edge slightly 

 and irregularly clouded, but the lines not reproduced beneath. 

 Expanse of wings, 9 , 40-45 mm.; length of body, 9,17 mm. 

 Effy. — IJemisplierical, rather high, uot liattened; the empty shell chalky white, under a 



lens appearing to be very finely pitted; under .J-inch objective seen to be ornamented with dense 



close-.set rounded granulations, with no space between them, and no polygonal areas; mieropyle 



ai>ical, distinct. Diameter, 0.7 mm. The oriUce eaten by the larva is irregularly oval. 



Jjarvit. — Somewhat like Nadala gibbosa, but "^he head is smaller, and it has no supraaual 



plate, and the body is smooth, not graiuilated. Head nearly as wide as the prothoiacic segment, 



but not so wide as the body; full and rounded, though a little flattened 



above; deep pea-green, but concolorous with the body. On the side a 



pink line edged above with white extending to base of the antenna'. 



Mandibles green at base, with an orange-red line along u])peredge. Tijis 



black. A short black line above at base of antenna'. Body noctniform, 



tapering towai'd the anal legs, which are short and small, no larger than 



the other abdominal legs, supraanal jilate small, rounded at the end, not 



large and corispieuous as in Nadata gibbosa. Segments not convex, but 



the sutures distinct. A faint double median, whitish, somewhat broken 



line, the two lines converging and forming a single one on Die middli' of 



the supraanal plate and tinged slightly with pink. A di.stinct lateral pink 



line begins on side of the head and extends to end of the body along 



the edge of supraanal plate. The line is somewhat linely brown, and is 



edged below with white. The whole body and legs pea-green, slightly 



darker below than along the back. Thoracic feet, greenish amber, spotted 



extermdly Mith black. Length, 0.40 mm. 



The following description of the larval stages, pupa, etc., are copied 



from Mr. Dyar's paper in Troceedings of the I'joston Society of Natural 



History, November, 1804: 



^'■FirHt larval stage. — The newly hatched larva is entirely shining yellow, 3 mm. long. Head 



cordate, as wide as high, pale brown, slightly shining; eyes black, mouth brown; width, 0.6 mm. 



Body slender, long, smooth, with minute blai^k seta; arising from inconsijicnous black dots. Anal 



feet extended nearly backward, slender, ])artly aborted. Color, leaf-green, shining, ayeUow shade 



stigmatally. All the feet black, contrasting.
