internal angle ; costal edge washed with orange yellow, mingling with the 

 ground color. 



" Under side of the primaries pale citron yellow, with a black central 

 point, the edge intersected with brown points ; the outer edge reddish near 

 the fringe. 



" Under side of secondaries yellow, sprinkled with ferruginous atoms, 

 with a blackish central point ; edge intersected with ferruginous points, 

 and marked near the external angle with a spot of the same color ; the 

 posterior half having four or five other spots of the same color, of which 

 two or three are in a line, and tending to form a transverse band ; the 

 middle of the outer edge more or less washed with ferruginous. 



" Female differs from the male in the upper side being yellowish white, 

 with a wider border, the quadrangular sinus more profound ; the anterior 

 edge of the secondaries widely orange yellow, and below, three ferruginous 

 posterior spots form on the secondaries a narrow, transverse, ferruginous 

 band. 



" Texas — Louisiana — Mexico." 



Among the other insects taken were Papilio cresp/iontes, P. turmis, 

 P. troilus, Colias phiiodice, Terias lisa, Argynnis cyhele, Phyciodes tharos, 

 Pyrameis huntera, P. atalaJita, Anchyloxypha numitor, Pholisora 

 catullus, Eudatnus tityrtis, Eicdryas grata., Leucariia unipuncta, Lucanus 

 lentus and Macrodactyius subspinosus. The latter species was very common 

 on the flowers of the tulip tree ( Liriodendron tu/ipi/era), which was then 

 blooming freely ; also on the sour gum or Pepperidge tree (Nyssa multi- 

 flora). 



The next morning we started early on our return journey and reached 

 Essex Centre in time to take the afternoon train home. Had the weather 

 been favorable we should doubtless have reaped a much richer harvest. 



THE HAIRY LARV^ AND THEIR PARASITES. 



BY FREDERICK CLARKSON, NEW YORK CITY. 



It is generally acknowledged by Entomologists that the hairy larvae, 

 such as the Arctians and their allies, very commonly escape parasitic 

 attack, a circumstance attributable to the fact, that in order to permit the 

 deposit of ova, these caterpillars must be discovered by the parasites in 

 favorable postures, or else worried by them into such, that the spines 

 separating, give the only opportunity for the insertion of the ovipositor.
