that their characters are those of two nearly allied but distinct ge- 

 nera. For his animal he proposes the name of Parmula cocciformis. 

 In 1832, Schlotthauber discovered the animal described by Spix in 

 the neighbourhood of Gottingen, and, following its development, 

 found it to be the larva of Microdon mutabilis. In 1839 he com- 

 municated to the Meeting of Naturalists in Pyrmont a full descrip- 

 tion of the metamorphoses of this species, which he proposed pub- 

 lishing ; but it seems never to have been printed. 



The author, in 1 844, met with bodies resembling coffee-beans, 

 with a reticulated surface, on the inside of the bark of oak-stumps 

 in the Neuhauser Forest, from which he obtained specimens of Micro- 

 don mutabilis. He afterwards found single pupae in similar stumps 

 inhabited by ants, and finally, also a larva, which, however, soon 

 died. M. Sauter has also met with these larvae ; and Dr. Hensche, 

 whilst residing at Kreuth, found amongst earth-dwelling ants three 

 Mollusk-like animals, which he preserved in spirits, and which 

 turned out to be larvae of Microdon. 



As the Microdon mutabilis is a British species, it might interest 

 some of our entomologists to look out for the singular larva here 

 referred to, as the nature of its metamorphosis, and especially 

 its relation to the ants with which it seems to be always associated, 

 appear to be by no means cleared up. — Sckriften der Kbnigl. phys.-

On a New Species of Bird of the Genus Lipaugus of Boie. 

 By P. L. Sclater, M.A., Ph.D., F.B.S. 



Lipaugus subalaris. 



Viridescenti-olivaceus, dorso imo, venire et cauda cinerascentio- 

 ribuS) cauda fere tota cinerea ; crisso albicante ; pilei semi- 

 cristati plumis interne nigris : gutturis et pectoris plumarum 

 scapis conspicue Jtavicanti-albis : plumis axillaribus et sub- 

 alaribus Icete citrino-Jlavis : alis fusco-nigricantibus, extus dorso 

 concoloribus : rostro et pedibus nigris. 



Hab. In rep. iEquatoriana, ad ripas fl. Napo. 



This Lipaugus will be easily recognized by the beautiful bright 

 yellow colour of the axillaries and under wing-coverts and the slightly 

 crested head, the feathers of which are black underneath. In struc- 

 ture it appears to be a member of the group Aulia : the outer and 

 middle toes being completely united to the end of the second pha- 

 lange, and the form otherwise resembling that of Lipaugus hypo- 

 pyrrhus. The single example in the collection of the British Mu- 

 seum, acquired in 1857, is labelled "Rio Napo." — Proc. Zool. Soc.
