403 Mr. E. S. Bagnall on neiv Thysanoptera. 



Abdomen nuicli as in D. major ; tube long, about 0'72 tlie 

 length of the head, about 5"0 times as long as broad near 

 base, narrowed in the distal fifth, the apex being about 0*6 

 as wide as near base ; surface sparsely and minutely setose. 



At once separated from D. major by the length of the head, 

 the non-prominent eyes, and the coloration of the tibiae. 



Type. British Museum of Natural History. 



Ilah. 1 ? , Madeira ( Wollaston). 



This makes the sixth species of the genus, eacli as yet 

 known from but a single examp'e. Ignoring D. monstrosus, 

 which becomes the type of a new genus characterized below, 

 the remaining five species fall into two well-defined groups 

 as follows : — 



1. Length 3*0 mm. or under, head shorter and broader, less 

 than twice as long as broad ; containing ampliceps, Bagn., and 

 laficeps, Bagn. 



2. Length more than 5*0 mm., head longer and 2 to 3 

 times as long as broad ; containing major, li&gx^., frontalisf 

 Bagn., and lonc/iceps, sp. u. 



Genus EGCHOCEPIIALOTHRirS, nov. 



Separated from Docessissophothrips, Bagn., by the extreme 

 form of the head which, viewed dorsall}', is as figured in the 

 original description of D. 7nonstrofius. It is extraordinarily 

 adpressed and, viewed dorsally, represents the end view of a 

 stoutish *' plate," with a slight swelling (representing the 

 cheeks) on each side of the marked carina. 



Type. Docessissophothrips monstrosus, Bagnall. 



b. Trichothr'ips group. 



(Edemothr'ips (?) propmqnus, sp. n. 



$ . — Length 1"8 mm. 



Colour brown, the last 4 or 5 abdominal segments darker. 

 Legs yellowish shaded with light grey-brown. First 

 antennal joint light yellowish-brown, 2 slightly darker, 

 3 brown with basal half clear yellow, 4 and 5 brown with 

 basal thirds yellowish, 6 to 8 totally brown. 



Almost the same as (Edemotlirips (?) hrevicollis, Bagn. 

 (Japan) in general form. Tiie head is not quite so markedly 

 convergent behind, the prothorax is not so short compared to 

 its breadth, and the tube is stouter.
