148 INSECTS AFFECTING THE ORANGE. 



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

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



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

 ing: "The parasite of the drop- worm is Ichneumon concitator Say, a 

 very common and somewhat variable species, which attacks all sorts 

 of Iarva3. It is one of the most common parasites of Clisiocampa amer- 

 icana." No mention of this species can be found elsewhere than in 

 Harris's writings, and the presumption is that a confusion has been 

 made between names of similar sound, and that either Pimpla 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 pine-needles, some of which are very 

 long and project beyond or out from the sides of the case. 

 The basket of the female is about 38 mm (1J inches) ; that of 

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

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

 chestnut-brown, and is 15 mm (-f- 6 inch) long. 



Fig. 66 represents the basket of the male of Psyche con- 

 fedcrata, with the pupa-shell protruding. (Reproduced 

 from Trans. Arner. Ent. Soc., vol. II, Plate III, Fig. 67.) 



The male remains unknown 5 it is a winged moth, which 

 probably resembles Psyche confederata G. and E., but is larger and pos- 

 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 Thyridopteryx. 



THE ORANGE BASKET-WORM. 



(Platceceiicus gloverii Packard.) 

 [Fig. 67.] 



A much smaller species than the preceding was first mentioned by 

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



* First Annual Report of the Injurious and Other Insects of the State of New York, 

 by J. A. Lintner, page 84. 



tThe male of Psyche confederata G. and R., is " entirely deep, smoky black. Anten- 

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

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

 (Trans. Am. Eut. 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.
