Cryptothrips insularis, sp. n. 



Lengtli about 2-25, brtadth of mesothorax 0*38 mm. 



Near C. dentipes, Ileut. Colour almc st black ; legs dark 

 blown, tibias somewhat lighter apically ; tarsi yellowish- 

 brown. Antennae concolorous with head, joint 3 yellow 

 dark brow n near apex. ' 



Form linear, apterous. 



Head as in dentipes, about 1-25 times as long as broad 

 behind eyes and about twice as long as the protliorax. 

 Eyes small, occupyino- 0-25 the length o£ head, moderately 

 finely facetted. Ocelli small, posterior pair widely separated 

 and touching inner margins of eyes. Antennas I'To times 

 the lenglh of head, inteimedlate joints not elongated as in 

 dendpes, 3^5 approximately subequal and but slb-htly lon-er 

 than 6. o j o 



Prothorax transverse, about 1-8 times as broad as lono- ; 

 t\vo fove«, one above the other, near each lateral mar<-ui! 

 Plerothorax only a little broader than tiie width across iore- 

 coxffi, transverse. Legs somewhat short. 



Abdomen elongated, linear, a little broader than the 

 pteroihorax ; segments 8-9 sharply narrowing to base of 

 tube. lube short, stout, Q-Q the lengtli of head. Set^ 

 nuleteiininable in the carded specimen.

The shape of the head is almost exactly as in C. deyitipes, 

 but not quite so broad. From this species it is readily 

 separated by its linear form, the short antenme (twice us 

 long as the head in dentipes) -And s\ioxt intermediate joints, 

 the darker fore-tibue, shorter legs, and the short tube, "which 

 in dentipes is as long as "the head. 



Genus MiCROCANTHOTHRIPS, nov. 



For some time I have been aware that my Ceplialothrips 

 spmosus could not be retained in that genus. A very stron*.- 

 aitiHeial light enables one to examine the femora tucked up 

 under the head through the dark chitin, and I have thus 

 drawn up the following biief diagnosis, which is suthcient to 

 cliaracterise the genus for the time being. U further speci- 

 mens do not come to hand, I propose to carefully remount the 

 unique preparation. 



It cannot be referred to any of the known genera with 

 armed tore-femora, and would seem to come in tlic Ilaijlu. 

 thrips group.
