REPORT 01' THE ENTOMOLOGIST. 243 



oidivora, and for specimens of the common " soft scale" of the orange 

 {Lecanium hesperidum), from which I have bred the same insect. And 

 June 23, 1880, I received oraiif^e twigs which were badly infested by 

 the latter bark-louse ; and att itched to the bark-lice were the character- 

 istic eggs of tliis moth. These observations indicate that this species 

 is widely distributed, and coulirms my conclusion that it is normally 

 predaceous. 



DESCRIPTIVK. 



Dakruma COCCir»IVORA. 



Expanse, lO-lS""" ; length of body, 4-8""'. 



g $ . — Head above dark ash-gray with a faint coppery reflection, below and behind 

 the eyes white. Eyes black and quite coarsely faceted. Lower surface of antennae 



Eale browu; upper surface dark gray with coppery and green reflection. Labial palpi 

 lack sprinkled with white scales, and with the base almost entirely white. Maxillae 

 rust red with the basal hali" clothed with white scales interspersed with a few black 

 ones. Thorax above and patagia dark gray with brown and green reflection. Abdo- 

 men annulated with brown and light gray ; the brown predominating above, the light 

 gray beneath. Fore wings light gray marked with brown and black. A light band 

 extends across the outer part of the basal third of the wing; the costal half of this 

 band is wide, reaching nearly to the base of the wings ; the remaining half is narrow. 

 Near the base of the wings there is a short transverse gray band which is sometimes 

 obsolete ; exterior to this is a short longitudinal black sjiot, which also varies greatly 

 in size and intensity of color. The light band which extends across the outer part of 

 the basal third of the wing is bordered externally by a dark band, which is narrow- 

 on the costal, and near the middle of the wing widens so as to reach the outer third 

 of the wing. There are two black dJscal spots which are sometimes distinct, but more 

 often united so as to form a single crescent-shaped spot openin;| outward. The mark- 

 ings of the outer third of the wing resemble greatly those oi Acrobasis nebulo, there 

 being a row of six or seven dark spots on the outer margin, and one-fourth of the 

 distance to the body a wavy light gray band parallel to the exterior margin, and 

 bordered on each bide with dark brown; the costal end of the outer of these brown 

 borders is usually darker and widened externally, forming a conspicuous black triangu- 

 lar s^jot. Lower siu'face of the front wings dark gray especially toward the apex, 

 with a faint brassy tinge. Hind wings light gray with the apex clouded. 



Thirty -four specimens examined, 18 ,?, 16 $. 



Chrysalis.-^Liength G.5 ™'". Color, dorsum dark brown inclining to blackish toward 

 anus, venter a little lighter, wing and antennal sheaths yellowish brown. AVing 

 sheaths reaching nearly to the 6th abdominal segment ; antennal sheaths reaching 

 to the tip of the wing sheaths ; dorsum densely punctured, venter less so ; stigmata 

 at the tips of slight protuberances ; tip of abdomen nearly surrounded by a whorl 

 (complete dorsally, incomplete ventrally) of small pointed tubercles. 



Larva. — Length of full-grown larva 8-12""". Body cylindrical, tapering slightly 

 toward each end. Head small, rounded, slightly bilobed, black and somewhat pol- 

 ished ; antennae white, 4-jointed, basal joint largest, second about one fourth the 

 length of the first, third nearly as long as the first but only about one-thixd as thick, 

 fourth a mere tubercle. Upper surface of the body a greenish black color with a 

 faint tinge of bronze ; prothoracic shield black, finely granulated, and with a pale 

 dorsal line ; anal shield a little darker than the body and sparsely beset with long 

 hairs. Stigmata and all piliferous spots brown with pale centers. Under surface of 

 the body bluish green. Legs black with the nodes bluish green; the ring of hookleta 

 of prolegs pale brown with light center. 



Egg. — White, faintly glossy ; oval in outline; i""" long, J""" wide ; surface closely 

 indented with large irregular five or six sided pits; the walls of the indentations form- 

 ing sharp ridges over the surface of the egg. 



Newly-hatched larva. — Length 5"". Color, dull white tinged with yellow ; head and 

 (horacic shield dark brown; mouth-parts dull yellow; body attenuated; head and 

 thoracic i)late large, round, flattened dorso-ventrally ; head with several long lateral 

 hairs; each abdominal segment furnished laterally with along stiff hair; thoracic 

 and prolegs strong and well developed. 



THE PALE DAKRUMA. 



{Dalcruma pallida [new species].) 



Closely allied to the species just described is another insect with simi- 

 lar habits ; for which, it being lighter colored in both larval and adult
