THRIPS INJURIOUS TO VINES IN CYPRUS. 199 



3. Deep ploughing or digging is very important, as thereby a large number of 

 insects may be buried. 



When the crop is already affected, the treatment recommended is to spray 

 the vines when the first shoots appear, about April, with IJ oke* of quassia 

 chips and 27 drams of Paris green in 100 okes of water. Repeat the spraying when 

 the flowers approach the time of opening in May. 



A NEW VINE THRIPS (THYSANOPTERA) FROM CYPRUS. 

 By Richard S. Bagnall, F.L.S. 



I have been asked by the Director of the Imperial Bureau of Entomology to report 

 upon, and, if necessary, describe a thrips which has been discovered to be distinctly 

 injurious to vines in Cyprus. Two curious species of the suborder Terebrantia have 

 been described from vines, viz., Retithrips aegypticns, Marchal, from Egypt and 

 Rhipiphorothrips bicolor (Bagnall) from Ceylon, and Karny and Doctor van Leeuwen 

 Reijnvaan record the following gall- thrips of the suborder Tubulifera from vines 

 in Java ; Dolerothrips picticornis, Karny, with an inquiline {Cryptothrips pachypus, 

 Karny) from Vitis papillosa, Gynaikothrips viticola, Karny, from V. lanceolaria and 

 a gall (species unknown) from F. mutahilis. 



Two specimens mounted on one slide have been submitted. Though apparently 

 of the same species, one of these possesses perfectly formed antennae of but 7 joints, 

 the comparative lengths of the joints differing from the corresponding joints in the 

 specimen with 8- jointed antennae. Further, the reduction in the number of joints 

 cannot be said* to be due to the fusion of any two joints. I describe the 8-jointed 

 form and should welcome further material. 



The species apparently belongs to the genus Cryptothrips of the nigripes, Rent., — • 

 major, Bagn., group. I say " apparently " advisedly, as I should have referred it to 

 the allied genus Gynaikothrips but for the fifth antennal joint being so nearly subequal 

 with the sixth and markedly shorter than the fourth. Apart from antennal 

 characters, this species differs markedly from G. viticola in the shorter head, the very 

 short prothorax and the coloration of the hind and intermediate tibiae. 



Suborder Tubulifera. 



Cryptothrips brevicollis, sp. nov. 



§. Colour brown to blackish brown ; fore tibia yellow, greyish brown basally, and 

 all tarsi yellow ; hind and intermediate tibiae yellow distally. Antennae with basal 

 joint concolorous with head, 2 yellowish distally, 3 lemon yellow, 4-7 yellow, the latter
