148 INSECTS AFFECTING THE ORANGE. 



parasites of the Xortberu Bag-worm.* The species varies in length 

 from about one-quarter of au inch to over half an inch. 



In Harris's Entomological Correspondence, \). 242, we find the follow- 

 ing: "The parasite of the drop- worm \fi Ichneumon concitutor Say, a 

 very common and somewhat variable species, which attacks all sorts 

 of larva?. It is one of the most common parasites of Clisiocampa amer- 

 icanaJ^ 'No mention of this species can be found elsewhere than in 

 Harris's writings, and tlie i)resumptiou is that a confusion has been 

 made between names of similar sound, and that either Pinipla conquis- 

 itor or Cryptus inquisitor was intended. 



THE CYLINDRICAL BAG-WORM. 



{Psyche sp.) 



The cases of a Bag- worm supposed to belong to the genus Psyche are 



sometimes seen upon orange trees; they are not spindle-shaped, as in 



the preceding species, but cylindrical, and the fragments composing the 



outside are laid on longitudinally. The fragments usually consist of 



bits of straw or dead i)ine-needles, some of which are very 



long and i)roject beyond or out from the sides of the case. 



The basket of the female is about 38""" (1^ inches) ; that of 



the male 25"™ (1 inch) in length* exclusive of projecting 



points. The female is wingless; its pupa-case is of a light 



chestnut-brown, and is 15"^"' {-^\^ inchj long. 



Fig. GG represents the basket of the male of Psyche con- 



rio. ^G.-Psyche fcclcrata, with the pupa-shell protruding. (Reproduced 



TT'ltiilr from Trans. Amer. Ent. Soc, vol. II, Plate III, Fig. 67.) 



Grote.) rjijjg male remains unknown ; it is a winged moth, which 



probably resembles Psyche confederata G. and E., but is larger and })os- 



sibly lighter in color.f 



The life-history of this Bag- worm is undoubtedly similar to, if not iden- 

 tical with that of Oiketicus and Thyridoi)teryx. 



THE ORANGE BASKET- WORM. 



{Platceceiicus gloverii Packard.) 



[Fig. G7.J 



A much smaller species than the preceding was first mentioned by 

 Mr. Glover, who gave au account of its habits in the Patent Office 



* First Auiuuxl Report of the Injurious and Otlicr Insects of the State of New York, 

 by J. A. Liutner, page 84. 



tTbe male of Psyche confederata G. ami K., is "entirely deep, smoky black. Auteu- 

 uaj plumose. Wings ample, closely scaled, rounded and full. * * * Expanse, 

 19mm. Length of body, 7'""\" The specimens described by Grote and Robinson 

 (Trans. Am. Ent. Soc, vol. II, p. 191) were sent from Texas. Plate III, fig. 67, gives 

 a representation of the basket of this species. Similar cases, which may possibly 

 belong to this species, have been seen upon the Orange in Florida.
