ART. 16 BUDWORMS OF GENUS HELIOTHIS CRUMB 3 



which is near the average height of the corresponding sj)iracles in 

 vireseens Fabricius (fig. 8) . Seta A3 usually distinctly more than the 

 wdtli of the ocellus removed from ocellus II (lig. 2). Line connecting 

 the insertions of setae A3 and 02 passing ])osterior to ocellus I or 

 tangent to its postero-dorsal margin (fig. 2). Head marked, if at all, 

 with brown freckles and sometimes with wliite reticulation. No 

 dark subraedian arcs. 



Body about 0.33 mm. long and 5.5 mm. broad; abdominal seg- 

 ments 1 to 4 of about equal widtli. tJie body tapering both anteriorly 

 and posteriorly from these: the skin set closely witJi small, retrorse, 

 spine-like granules wliich are white in the pale lines, dark elsewhere 

 dorsally, and pale on the venter; general color varying from red, 

 maroon, orange, yellow, and green to dark fuscous, often green dor- 

 sally v.itli a stripe including the pale middorsal line and the supra- 

 spiracular area dark. Broken white or yellowish longitudinal lines, 

 often obscure in their relationsJiips, occur as folloAvs: middorsally, 

 bordering the fuscous middorsal stripe, through setigerous tubercle I, 

 between tubercles I and II, through tubercle II, ventrad of II, and 

 several very indefinite in the supraspiracular area. A strong yellow 

 or pale line or narrow stripe margining the supraspiracular area ven- 

 trally. Venter tending to be white mediall3^ Spiracles in the sub- 

 spiracular stripe, black with yellow centres. Setigerous tubercles 

 large and often somewliat conical, I somewhat larger than II on 

 abdominal segments 1, 2, and 8 but not conspicuously so; the tvibcr- 

 cles witliout spinules excepting rarely a few at base. ( 'Crvical shield 

 usually with the lateral margins infuscated. Anal shield concolorous 

 with adjacent parts. Head of tJie general body color, often flecked 

 with brown and sometimes reticulate with white, without fuscous 

 submedian arcs or recitulation. Claw of legs with tlie base broadly 

 angulate (fig. 4). 



Labial palus with the segments in the proportional length of 18, 

 3, and 4, the basal segment with a long acutely conical papilla 

 a])ically (fig. 5). Spinneret nearly times as long as the median 

 breadth, tapering toward the truncate apex (fig. 6). Mandible as 

 in Figure 10, the first ventral rib usually produced inward into a thin 

 lobe near tlie base, or the produced margin may extend along most of 

 the length of the rib. Anterior half of hypophar}mx clothed sparsely 

 with very short, stout spines, heavier postero-laterally; lobes of the 

 maxillulae clothed witli extremely fine hairs; bla(k> of the maxihulac 

 with about 12 flat, triangular, toothlike i)rocesses on the free margin. 



Head setae and ])unctures as follows: A2 distinctly nearer to Al 

 than to Pa; Aa slightly nearer to A3 than to A2; A3 slightly more than 

 the ocellar width removed from ocellus II; Pa, Aa, and A3 not in a 

 straight line; ocellus VI distinctly nearer to 01 than to 03; 02 nearer 

 to A3 than to Ll ; 02 slightly nearer to A3 than to 01; lil distinctly
