64 INSECUTOR INSCITlit MENSTRUUS 



joints 3, 4, and 1 2, as in Composia, but with an additional pair. Wart 

 formation as in Composia, but the warts larger and crowded, so that 

 tubercles i are hised on the dorsal line, iii nearly surrounds the spiracle 

 with iv, to which it is closely appressed. 



Pericopis leucophaea Walker. 



Lana: Dyar. Proc. Ent. Soc. Wash., xiii, 229, 191 1. 

 Wart formation as in Composia, the second wart on joint 4 completely 

 united with the first and indistinguishable. Longitudinal and transverse 

 banding both present, the latter irregular. The markings on joint 6 are 

 very variable, differing often on the two sides of the same specimen. 



Pericopis lycaste Klug. 



Larva: Dyar, Proc. Ent. Soc. Wash., xiv, 56, 1912. 

 The body is purple, the anterior halves of the segments black, except 

 joint 4, which is largely luteous, and joint 12, which has a little of this 

 color. The banding is irregular, the warts yellow-brown, but black on 

 joints 2, 3 (laterally), 5, 6 (in part), 1 I (except tubercle iii), and 1 3 

 (except the anal plate). The hairs are rather soft and dense, but not 

 concealing the body, rather long, especially toward the extremities ; no 

 single discolorous ones. The pale warts contrast with the darker body. 

 The hairs are more developed than in the species previously mentioned. 



Pericopis thetis Klug. 



Larva: Dyar, Proc. Ent, Soc. Wash., iv, 407, 1900. 



I described this larva as Daritis howardi Hy. Edw., but I do not be- 

 lieve that there is really cuiy specific difference between howardi and 

 thetis. The larva possesses both longitudinal and irregular transverse 

 banding. The general hair development is less than in l})caste, but is 

 peculiar in having the short, spiny, branched hairs on wart ii, evidently 

 of an irritating defensive nature.
