ME. R. S. BAGNALL ON A COLLECTION OF 



mention that tbe Bromeliaceous species^ Eupatldtlirips affinis, was collected 

 by Mr. Hugh iScott, to whom I am indebted for the single specimen, and 

 I trust that renewed search in its apparently specialised habitat will result in 

 the discovery of more examples. 



In raising the Eupathithrips group and Chirothripoldes each to family rank, 

 I do so reluctantly and provisionally ; that they are sharply separated from 

 the heterogeneous Fldoeothipidcv (s. 1.) is evident, but it will only be after the 

 examination of a great deal moi e material and a close analysis of our known 

 Ibrms that we can hope to put the Tubilifera upon a sound working basis. 

 Meantime, by recognizing and setting aside these well-defined groups, 

 we, by elimination, make work upon the residue a little more easy. 



As a mark of gratitude and esteem, I have pleasure in naming Craniotlirips 

 uricld in Mr. Urich's honour. 



Suborder TEREBRANTIA. 



Family ^ o l o t H R i P i D ^. 



Subfamily ^olothripinj^. 



Genus MiTOTHRiPS, Tryhom, 1912. 



Near ^Eolothrips and allies, and readily distinguished by the extra- 

 ordinarily long and slender antenna3 caused by the elongation of joints 3 

 and 4, which are apparently without sensoria or sense-areas of any kind. 

 Fore-wings without cross-veins, broadened distally. 



Eyes larger, ocelli normal. Anteimte at least times as long as tlie head, 

 joints 2-4 light; 4 longer than 3, and 5-9 together only 0'2 the length 

 of 3 and 4 together Mitothrips mec/alops, Trybom.- 



Eyes smaller, front ocellus smaller than others. Antennae abont 3*5 times as long 

 as head, joints 1-4 light; 4 shorter than 3, and 5-9 together more than one- 

 half (0'57) the length of 3 and 4 together Mitothrips petulans, sp. n. 



Mitothrips petulans, sp. n. (PI. 48. figs. 1-5 ; PI. 49. figs. 1 & 2.) 

 ? . Length a little more than 2"0 mm., breadth of pterothorax 0"31 mm. 

 General colour dark brown, mesothorax lighter, and abdominal segments 

 1 to 3 white or yellowish- white, excepting where joined to each other, 

 and there tinged with reddish-brown ; segment 10 light yellow. Antennal
