Amorphothrips klebsi Bagnall, 1924I1 : 252. 



The description of this genus and species was quite inadequate and the type 

 specimen has not been found in Bagnall's collection. The published data were ; 

 sex uncertain, in Baltic Amber, Koenigsberg Coll., labelled Dr. Richard Klebs, 

 Mus. Stanten and Becker. 



Caliothrips cordatus (Bagnall) comb. n. 



Selenothrips cordatus Bagnall, 1924c : 131. 



The specimen is well cleared and the sculpture of the body is easily observed. The sculptured 

 reticles of the head, pronotum and mesonotum have internal wrinkles, and although the 

 abdomen is strongly contracted the sculpture is very similar to that found in striatus Hood. 

 The first vein of the fore wing bears 5 + 2 setae, and the second vein bears 4 setae opposite 

 the interval in the first vein. 



Holotype $. In Baltic Amber, without data. 



ELECTROTHRIPS Bagnall 



Electrothrips Bagnall, 1924b : 251-252. Type-species E. hystrix, by monotypy. 



Electrothrips hystrix Bagnall 



Electrothrips hystrix Bagnall, 1924b : 252. 



Three pairs of ocellar setae are developed, pair III arising within the ocellar triangle. Pairs 

 II and III are very long, subequal in length to the single pair of elongate postoculars (50(1.). 

 The anterior margin of the pronotum is partially obscured but apparently lacks elongate setae, 

 however there are two pairs of elongate postero-angulars. The costal setae on the fore wing 

 are long and stout and the first vein is apparently close to the costa. The antennae are probably 

 eight-segmented, V being longer and stouter than VI. Most of the specimen is obscured by 

 fractures in the amber. 



Holotype $. In Baltic Amber, without data. 



EOCEPHALOTHRIPS Bagnall 



Eocephalothrips Bagnall, ig24g : 160. Type-species Thrips capito Schlechtendal, 1887 : 579, 

 by monotypy. 



This genus was erected for the species capito which Schlechtendal figures as having 

 the bases of the antennae broadly pyramidal. The text states that the median 

 antennal segments are not clearly visible.
