Two females off Vespertilio serotinus, obtained at Malcoci Tulcea, 

 Eoumania, on May 4th, 1908, by A. Eettig. 



4. — Ctenophthalmus pkovincialis, Rothscli. (Fig. 3). 

 C. provinrialis, Rothscli., Ent. Mo. Mag. (2), vol. xxi, p. 207, Fig. 3 

 (1910). 

 This species was described from a single male found on Mus 

 sylvaticus at Valescure, South France (not Valescura, Portugal, as 

 misprint^ed in the original description) . Dr. K. Jordan caught a series 

 of both sexes of the same insect in July of this year at Valloire, Savoie, 

 off Arvicola agrestis. The males agree well with the type specimen. 

 The female is distinct from that sex of C. ayyrtes Heller (1896), and 

 agrees with C. hse.ticus, Rothsch. (1910), in the absence of a narrow 

 lobe beneath the large one in the seventh abdominal sternite. This 

 sternite is characterised in G. provinrAalis by the large lobe being 

 emarginate as shown in the figure (fig. 3). Sometimes the sinus is 

 deeper, in which case the lower portion of the lobe is transformed into 

 a small process, which is probably homologous with the narrow separate 

 lobe fomid in C. agyrtes.

THREE SPECIES OF THYSANOPTERA (TUBULIFEBA) NEW TO THE 

 BEITISH FAUNA. 



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



Of the following three species, all of which are described in Uzel's 

 " Monographie der Ordnung Thysanoptera," the occiu-rence of Lio- 

 thrips hradecensis is perhaps the most interesting, there having been 

 but one example previously known. The last-mentioned insect is 

 apparently attached to elm. 



The other two species are recorded on the strength of single 

 pinned specimens in the British Museum. 



Sub-Order TUBULIFERA. 



Cryptothrips lata, Uzel. 



" Monographie der Ordnung Thysanoptera," p. 230, pi. iii, fig. 24, 

 pi. vii, fi.gs. 118—122, 1895. 



A single British example is in the British Museum. A very broad 

 and distinct form, which is most closely related to G. nigrijies (Renter), 

 from Finland, differing chiefly in its shorter and broader head, and 

 the relatively longer antennae.
