5. Mesos&mia Asa. 



Male. Upperside. Dark brown. Anterior wing with 

 the base, which is brilliant blue, marked by a band in the 

 cell J a spot below it, the usual round eye-like spot (which 

 has three white dots), and a band below this, all black. 

 Posterior wing brilliant blue, with a broad dark brown 

 outer margin. 



Underside. Gray-brown. Each wing with the central 

 black eye bordered with green, with three white dots on 

 the anterior wing, and one on the posterior wing : pre- 

 ceded on both wings by a short band of gray and dark 

 brown, and followed by a similar band which crosses both 

 wings, by a broad band of dark brown, and a series of 

 submarginal brown spots. 



Female. Dark brown. Anterior wing crossed beyond 

 the middle by a broad white band : the central black spot 

 with a band of yellow on each side. Posterior wing mark- 

 ed as on the underside (but without the central spot), 

 which does not differ from the male. 



Exp. 1 j^ inch. 



Hah. — Nicaragua. 



In the collection of W. C. Hewitson. 



Near to M. Telegone, the underside of which is nearly 

 the same. 



6. Nymphidium OncBum. 



Male. Upperside. Dark brown, the outer margins 

 with the usual arched black spots, bordered with white ; 

 a large triangular space of white common to both wings ; 

 each wing* with a large orange spot at the anal angle. 

 Anterior wing with three large orange spots near the 

 base, and a spot of white at the apex of the large trian- 

 gular space of white. 



Exp. 1^ inch. 



Hah. — Nicaragua. 



In the collection of W. C. Hewitson. 



Nearest to N. Lysimon, but differs from the other 

 species in having conspicuous orange spots near the base 

 of the anterior wing. 



The other new species in Mr. Belt's collection are 

 small, and must be left for illustration by figures.
