white line on discocellular vein; outer area beyond sub- 

 terminal line red-brown, terminal dots confluent, form- 

 ing a more or less continuous blackish line along termen; 

 cilia reddish brown. Hind wing smoky white; the veins 

 darkened; a very narrow dark shade along termen; ciha 

 whitish, cut by a dark subbasal liae. Alar expanse, 

 23-28 mm. 



Male genitalia of the majorella type but with uncus 

 short, broad, its terminal margia angulate. Harpe with 

 slender, digitate clasper. Viuculum narrower, more 

 gradually tapered. Penis with numerous anterior 

 spines, but without the usual enlarged posterior cornu- 

 tus. Female genitaha with bm-sa copulatrbc greatly 

 reduced, much shorter than ductus bursae. 



Type locality: Chiricahua National Forest, Ariz. 

 (typeinUSNM). 



Food plant: Pinus chihuahvxma. Larvae feeding 

 in the cones. 



Disteibution: Arizona, Chiricahua National For- 

 est (May); Redington (Aug.). 



This species, with pygmaeella, forms a connecting link 

 between the smooth-winged Dioryctria species and those 

 with distinctly roughened scales formerly referred to 

 Pinipestis.

FiGUEB 874 



Pinipestis horneana Dyar, Ins. Insc. Menstr., vol. 7, p. 43, 1919. 



MaxUlary palpus of male squamous. 



Forewing bright red-brown shaded with white, the 

 ground color brighter and more on the red shade than 

 that of any of the foregoing species; a rather broad, 

 diffused, white shade preceding the antemedial line 

 and two rather large, confluent patches following it, one 

 in the cell and another in lower fold; a strong broad 

 oblique white shade extending from inner margin near 

 subterminal line to costal beginning of that line and 

 fusing with and more or less obscuring it; the scales of 

 these white areas as well as those of the white discal 

 spot decidedly roughened; a narrow band of appressed 

 white scales along terminal margin; antemedial line 

 narrow, white, nearly vertical, notched above and below 

 its middle, followed on basal half by a faint, nari'ow, 

 gray outer bordering line; subterminal white line rather 

 close to outer margin, vertical with a slight bulge at 

 middle; terminal black dots narrow weak, confluent. 

 Hind wing yellowish white with a very faint smoky tint; 

 veins but shghtly darkened; a fine, pale brown line along 

 termen. Top of head and collar of thorax red-brown; 

 remainder of thorax whitish. Alar expanse, 25-28 mm. 



Genitaha similar to those of zimmermani. 



Type locality: Herradura, Pinar del Rio, Cuba 

 (typeinUSNM). 



Food plant: Pinus sp. 



Ejiown only from the female type and a male from 

 the same rearing. Dyar in his original description gives 

 Santiago de las Vegas as the type locaUty, but was evi- 

 dently in error. Dr. S. C. Bruner, Chief of the De- 

 partmenta Agron6mica of Cuba, has given us the cor- 



rect locahty. The species is easily distinguished from 

 others of the zimmermani complex by the bright reddish 

 ground color of its forewings and from the other red- 

 winged American species by its strongly tufted fore- 

 wings. 



The labial palpi of the male are more closely appressed 

 to the face than those of most Dioryctria species.

Maxillary palpus of male squamous. 



Forewing smooth except for a slight roughening of 

 the white scales of the transverse lines and discal spot; 

 purplish gray with irregular patches of dull dark red 

 and a more or less extended white dusting; the red 

 patches consisting of a rather broad band preceding the 

 antemedial line, a similar band from middle of iimer 

 margin to cell and a rather broad shade outwardly 

 bordering the subterminal line; the white dusting con- 

 centrated over the median areas not occupied by the 

 red median band, in subbasal area just behind the red 

 band, and along termen following the red subterminal 

 shade; transverse lines thin, whitish, rather faint (under 

 magnification, the scales silvery and somewhat rough- 

 ened); antemedial line oblique, notched at vein lb, 

 bordered outwardly by a black line which expands at 

 costa into a black patch; subterminal line sinuate- 

 angulate with a broad, black, inner, bordering line; 

 terminal dots fused into a fime black line along termen; 

 white discal spot an oblique lunule; a fine black line 

 along the lower half of the inner margin of the red band 

 preceding antemedial line (but not a raised-scale ridge 

 as stated by Ragonot) ; also some dusting of black scales 

 on the red of extreme basal area. Hind wing pale smoky 

 gray; the veins darkened and a narrow dark shade 

 along termen. Alar expanse, 15-21 mm. 



Male genitalia with a cluster of long strong posterior 

 spines and one or two weak anterior spines on penis. 

 Female genitalia with the spine clusters in bursa con- 

 sisting of narrow, straight bands of slender spines; 

 ductus bursae sclerotized from junction with bursa 

 almost to genital opening. 



Type locality: Florida (type in Paris Mus.). 



Food plant: Taxodium distichum. Larvae in the 

 cones. This record from reared series from Maryland 

 (Heinrich, 1920) and Virginia (Busck, 1927) in the U. S. 

 National Museum. 



Distribution: Florida, Winter Park (July) ; Virginia, 

 Cape Henry (Aug.) ; Maryland, Pokomoke (Aug., Sept.). 

 Probably over the range of its host plant. 



A distinct, easily recognized species, intermediate be- 

 tween the smooth-winged species and those with definite 

 raised-scale ridges.
