Mr. R. S. Baoii.'iU on new T/iijsanoptera. 293 



brownish-yellow disfnlly, (3-8 light brown, 6 yellowish 

 distaliy. Wings clear. 



Head a little more tlian 1'5 times as long as broad ; cheeks 

 not couverginj^ posteriorly ; vertex raised in form of liump. 

 Antennse I'o times as long as head, inserted below vertex, 

 approximate, joint 3 not; as broad as 2 and 4 ; relative 

 lengths :— 16 : 18 : 31 : 31 : 24 : 23 : 17 : 9. Eyes occupy- 

 ing one-third the length of head; fore-ocellus on apex of 

 raised vertex, dirictecl forwards. Postocular bristles set 

 well in towards mid-line, very short and weak. Mouth-cone 

 long and pointed, reaching to base of prosternutn. 



Prothorax with anterior margin strongly emarginate, more 

 than twice as broad across hind-angles as long through 

 middle, but only 1"5 times as broad as long, taking the 

 length from posterior margin to a line drawn across anterior 

 angles. Alid-hiteral sotaj absent, others short, the postero- 

 marginal ones about 0*4 the length of prothorax thr(jugh 

 middle, and those on anterior margins about 0'2 as long. 

 Pterothorax X'O times as broad as the prothorax and a liltle 

 longer than broad. 



Abdomen no broader than pterothorax, gradually nar- 

 rowing to segment 7 and thence a little more rapidly to tube. 

 Tube very short, not one-halt (0'47) the length of head and 

 only 1*38 times as long as segment 9. Sides straight, eveidy 

 narrowed from base, where it is about 2'2o times as broad as 

 at apex and more than 0*6 as broad as long. Bristles at tip 

 and on segment 9 about 0"8 the length of tube, weak and 

 colourless ; two pairs of wing-retaining spines on each of 

 the tergites 2 to 7. 



Separated from elonqatus, Bagn. (Neotropical), which has 

 also a very short tube, by the coloration of the antennas. 



Type. In Hope Collections, University Museun), Oxford, 

 IJub. One ? , ]\latarieh, near Cairo, from Zyziphiis^ 

 9.ix. 1911 {F. C. Hillcoch). 



The type-specimen is cleared in potash, so that it is possible 

 to get but an approximate idea of the coloration ; the colour 

 of the antenna2 is taken trom a second example captured by 

 Prof. Sahll>erg at lleluan. This example, carded, showed 

 a pronounced metallic purplish coloration, but I do not think 

 it was natuial. 



Cri/ptotlirips tenuipilosus, sp, n. 



? . — Length 2'4 mm., breadth of mcsothorax 0'52. 

 Colour chestnut to dark grey-brown, apical half of tube
