than long as in collinsi, but the coloration of the antenna? is distinctive, 

 the 5th antennal joint is fusiform, and the tube is nearly as long- as 

 the head. 



Of the American species, xanthosis, Hood, insolens, Hood, uzeli, 

 Hinds, have the tibiae yellow; funebris, Hood, has the antenna? 

 uniformly brown ; juniperinum, Hood (somewhat near collinsi), has 

 minute prothoracic seta? ; and microps, Hood, has a peculiarly shaped 

 head with distinctive chaetotaxy. Jennei, Jones, and armiger, Jones, 

 have the innermost pair of bristles on the 9th tergite knobbed, and 

 the antenna? coloured somewhat as in minor. Pergandei, Hinds, is very 

 near collinsi, but has the base of the 6th antennal joint yellow, the 

 pterothorax narrower, and the 5th antennal joint apparently fusiform, 

 whilst raptor, Crawford, is not unlike ellisi, differing in the shape of 

 the head, the coloration of the antenna?, and in the postero- marginal 

 seta? of the prothorax, which are much shorter than those at posterior 

 angles. 



Of the two described African species, hoodi, Bagn., is a very dis- 

 tinctive one ; natalensis, Tryb., is near collinsi, differing in its coloration, 

 relative lengths of antennal joints, chaetotaxy of abdomen, etc. 



Cryptothrips latus, Uzel. 



One example and larva? taken by Mr. Wm. Harvey at Bournemouth, 

 January, 1913. Several examples and larva? amongst dead branches 

 and old bean sticks, Hogley Bog, near Cowley (Oxon), September, 

 1913, with an undescribed HaplotJirips. Previeusly known as British 

 from a single specimen, without data, in the British Museum. 



Cryptothrips major, Bagnall. 



Described from a single Norwegian example, Mr. C. B. Williams 

 has had the good fortune of discovering both sexes and larva? in Surrey 

 and is bringing forward the species.* I have taken larvae that agree 

 well with those submitted to me by Williams in Oxfordshire and 

 Warwickshire, and possess a single £ taken by Mr. J. Collins at Water 

 Eaton (Oxon) in August, 1913. 



Cephalothrips monilicornis (Eeut.). 



Several wingless examples on grass from the Euskin Reserve, 

 Cothill (Berks), September, 1913.
