BAGNALL'S THYSANOPTERA 159 



' Heliothrips ' scudderi Bagnall 



(Text-fig. 79) 



Heliothrips scudderi Bagnall, 1924c : 1 31-132. 



The wings are folded on the back of this specimen, but tergite II is apparently constricted 

 basally and on tergite VII a curved wing retaining seta is visible on one side. No major setae 

 can be distinguished on the fore wings although the first vein is apparently fused with the costa, 

 and costal fringe cilia are present. The specimen appears to be congeneric with Dinnrothrips 

 frontalis, but surface damage to the amber piece and also internal fractures make definite 

 generic placement impossible at present. 



Holotype $. In Baltic Amber, IB 443. 



Oxythrips physothripoides (Bagnall) 

 (Text-fig. 81) 



Homothrips physothripoides Bagnall, 1924c : 131. 

 Oxythrips physothripoides (Bagnall) ; Mound, 1968b. 



The holotype is a male and bears a pair of stout thorn-like setae medially on tergite IX. 

 The single pair of pronotal postero-angular setae are about 40^ long. The first vein of the fore 

 wing has a wide interval in the setal row and two setae apically, the second vein bears seven 

 setae. The bases of the antennae obscure the head but a forked sense cone is visible on antennal 

 IV. 



Priesner (1929b) has described female specimens in the genus Oxythrips from 

 Baltic Amber.

Physothrips connaticornis Bagnall 



Physothrips connaticornis Bagnall, 1924c : 133. 



The holotype female has not been found in Bagnall's Collection. The original 

 publication gave no reference number. 



Physothrips gracilicornis Bagnall 



Physothrips gracilicornis Bagnall, 1924c : 132. 



The holotype female has not been found in Bagnall's Collection. The published 

 data were Phys. Oek. Ges. No. 9855. 1. 14. No. 2. 



Physothrips succineus Bagnall 



Physothrips succineus Bagnall, 1924c : 132-133. 



The specimen is a distorted teneral female and its generic position is not clear. There are 

 three pairs of ocellar setae, pair III 30^ long, just within the lateral sides of the ocellar triangle. 

 The postero-angular pronotal setae are 50^ long, but the posteromarginals are not visible. The 

 first vein of the fore wing has two distal and nine basal setae, the second vein has thirteen setae. 

 The eighth tergal comb is not visible.
