INSECTS IN BURMESE AMBER. 



By T. D. a. Cockerell. 



The following species were found in Amber, recently received 

 from Mr. Swinhoe, and will be placed in the British Museum. 

 I have not described all the specimens in the collection. Some 

 are so placed that they can only be properly investigated if the 

 amber is '■cut to bring them closer to the surface ; while others, 

 especially small Coleoptera, are beyond my powers of analysis 

 and classification. Thus future workers, interested in special 

 groups, will find various interesting undescribed forms which I 

 have been compelled to ignore. 



HOMOPTERA. 



Aleyeodid^. 



Aleurodicus burmiticus, n. sp. (Fig. 1.) 



(^ . Length about 960 /x ; wings hyaline, anterior pair faintly 

 dusky, but no spots ; forceps elongate, with a small tubercle on outer 

 side about 112//, from tip. The following measurements are in 

 microns : Antennae about 295 ; hind wing about 720 long and 335 

 broad ; hind tibia 240 ; first joint of hind tarsus 80, second 50. 



In Burmese amber, received from Mr. R. C. J. Swinhoe, a 

 typical Aleurodicus, principally remarkable, as compared with 

 living species, for the minute size. It is the first occurrence of 

 the genus in the fossil state. In the modern fauna most of the 

 species of Aleurodicus are neotropical, but evidently the genus 

 has long existed in the Old World. 



CORRODE NTIA. 



PSOCID^. 



Psylloneura (?) perantiqiia, n. sp. (Fig. 2.) 



Anterior wings about 2,080 microns long, clear, w'ith dark veins, 

 more or less interrupted by light sections or spots ; tarsi three-jointed,
