44. Colcenis tithraustes. 



Exp. 2'90 in. Very closely allied to Colcenis telesiphe^ Hew., 

 but differs in having the transverse band of the hind wings 

 yellow instead of white ; in other respects the two species are 

 quite alike.

Ohs. Mr. Buckley also took specimens of this species in 

 Ecuador. 



45. Eurema Arcmi. 



^ . Exp. 2'50 in. Like E. dione^ Latr., but darker ; a 

 broad subtriangular tawny band crosses the anterior wing 

 from the costa towards the posterior angle ; the inner edge of 

 this band is nearly straight, and passes close to but outside 

 the elongated transparent spot between the first and second 

 median branches. There are no transparent spots near the 

 apex as in E. dione. The undersides of the two species are 

 quite aUke.

46. Melitcea crithona. 



Exp. 1*70 in. Outer margin of anterior wings somewhat 

 strongly emarginate, dark brown ; anterior wing with two 

 deep-tawny spots in the cell, three others between the median 

 nervure, its second branch, and the inner margin ; a broad 

 tawny transverse band crosses the wing from the costa to the 

 posterior angle : posterior wings with three undulating narrow 

 tawny lines parallel to the outer margin. Underside with 

 band on the anterior wings as above j basal half with ochre 

 spots margined with dark brown ; apex reddish brown, with a 

 few whitish spots : posterior wings grey, with irregular brown 

 lines ; outer margin dark brown, running into a large patch 

 near the costa ; apical angle grey, with dark lines ; the mark- 

 ings of the underside of the posterior wings much resemble 

 those of M. ardys, Hew. The band across the anterior wings 

 is somewhat like that in M. elaphicea^ Hew.

Ohs. This is a well-marked species, and distinct from any 

 I have seen. 



47. Leptalis cinera^cens. 



(J . Exp. 2*45 in. Antennae black, palpi greyish, head 

 and thorax black mixed with grey : anterior wings pointed, 

 posterior angle rounded, not projecting ; black, with five
