DESCEIPTIONS OF THREE NEW SCANDINAVIAN 

 THTSANOPTEBA (TUBULIFEBA) . 



BY RICHARD S. BAGNALL, F.L.S. 



In June, 1909, I had occasion to journey to Norway on certain 

 business matters, and returning by Sweden and Denmark I was able 

 to do a little collecting in each of these countries, devoting my atten- 

 tion chiefly to the Thysanoptera and a section of the Collembola. In 

 these groups I was fortunate enoiigh to discover several new species, 

 of which three, belonging to the TubuUfera, are here described. 



I was greatly impressed by the large variety of thrips that were 

 to be seen iu the greatest profusion on the hills and in the beautiful 

 forests and fields of southern Norway, and believe that many species 

 vet remain to be discovered in that country, whilst a number of those 

 described by Reiiter from Finland will undoubtedly be met with. 



Sub-Order TUBULIFERA. 

 Cryptothrips major, sj). nov. 



9 . Length, 3'4 mm. 



Blackish-brown, segmentation of abdomen lighter, third antennal joint 

 yellow tinged with light brown towards apex. 



Closely related to C. latus, Uzel, and C. nigripes, Kent. Head with cheeks 

 straight, widening from eyes to base, where it is widest ; space between eyes 

 equal to twice the breadth of an eye ; ocelli small, posterior pair very widely 

 separated and placed above a line di-awn through posterior third of eyes and 

 close to their inner margins. Antennae more than one and a half times as long 

 as the head; relative length of joints, 5 : 7: 11: 10: 10: 8'5: 5'5: 5. 



Prothorax transverse, only slightly more than one-half as long as the head 

 and more than twice as broad as long. Spine at anterior angle moderately 

 lon<'', and pair at posterior angles very long (one-half the length of prothorax), 

 and slightly curved. A minnte seta on each side of the median line near 

 posterior margin. 



Pterothorax transverse ; wings absent. Legs as in C. latus, tarsi only 

 slio"htly lighter in colour than the tibiae. Abdomen oblong-ovate, one and 

 one half times as broad as prothorax, sides subparallel to the sixth segment and 

 thence o-radiially converging to base of tube. Tube two-thirds the length of 

 head sides straight, converging from base to tip ; twice as broad at base as at 

 tip and two and three-qviarters as long as broad at base. Terminal hairs and 

 those at apex of ninth segment two-thirds the length of tvibe ; other abdominal 

 hairs short, moderately strong and light coloiired. 



Hahitat : Norway, a single example taken by beating the leaves 

 of a lime tree. Bygdo, near Christiania, June 27th, 1909. ^ 



From C. nigripes this species may be separated by its larger size, 

 its shorter and broader head (twice as long as broad in C. nigripes) 

 and relatively longer antennae. C. major also closely approaches
