SOME NEW AND LITTLE-KNOWN EXOTIC THYSANOPTERA 529 



slightly shorter than either of the three preceding joints ; 

 seventh linear, four-fifths the length of sixth, and the apical 

 pointed at tip and three-fifths the length of the penultimate. 



Prothorax transverse, one-half as long as broad (excluding 

 fore-coxae) ; spine at each posterior angle exceptionally long, 

 being more than two-thirds the length of prothorax ; a minute 

 seta at each anterior angle ; others apparently obsolete. 

 Pterothorax about as broad as long; sides of metathorax 

 slightly arcuate and narrowed to base of abdomen ; legs 

 moderately slender, fore-femora only slightly thickened, and 

 the fore-tarsi unarmed. Wings reaching to the seventh 

 abdominal segment, median vein apparently obsolete. 



Abdomen long and slender, segments one to seven strongly 

 transverse, and each narrower than the preceding, and parallel 

 laterally; tapering gradually from the middle of the eighth 

 segment to tube. Tube one and one-sixth times the length of 

 head, slender, and longer than the two preceding segments 

 together, narrowed slightly from the apical third to tip. 

 Terminal hairs and those on the ninth segment slender, about 

 three-quarters the length of tube. Abdominal spines slender, 

 pale and not very conspicuous. 



?. Abdomen in the female a little broader than in the male, 

 practically paralled-sided from the first to the seventh 

 segment, and from thence gradually narrowed to tube. 



Type. — In the Copenhagen Museum. 



Habitat. — Both sexes collected by Dr. Meinert in Madeira. 



L. flavicoi'nis may readily be separated from Leptoth7'ips 

 ( Cryptothrips) aspersus Hinds by its larger size, the excep- 

 tionally long bristles at posterior prothoracic angles, as well 

 as by the very long tube. 



Genus COMPSOTHRIPS Renter, 1904 



Compsothrips albosignatus (Renter). 



Leyden Museum. — Five specimens collected by Mr. F. 

 Ancey, Marseilles. Apparently the first record of this insect's 

 occurrence in France.
