Cryptotlirips citricornis, sp. n. 



$ . — Forma aptero. 



Length about 2*5 mm. 



Elongate and linear. Colour chestnut to grey-brown; 

 metathorax and abdominal segments 1 to 7 lighter, tinged 

 with yellow. Antenna? yellow, sixth joint very faintly and 

 the penultimate and apical joints tinged with grey ; all 

 femora grey-brown, with the extreme apices faintly yellowish ; 

 all tibiae and tarsi lemon-yellow. Hypodermal pigmentation 

 deep and widely diffused. 



Head almost as in icarus, Uz., not quite 1*5 as long as 

 broad just behind the eyes (where it is broadest), and nearly 

 twice as long as the prothorax, which is strongly transverse. 

 Ocelli moderately large, remote from inner margins of eyes. 

 Postocular and all prothoracic setae well developed, yellow. 

 Wings and wing-retaining spines absent. Tube about 0*65 

 the length of the head and 2*3 times as long as broad at base. 

 Apical bristles nearly as long as tube. 



Related to icarus, Uz., from which it may be distinguished 

 by its larger size, more elongated body, and also by its yellow 

 antennae, and the dark femora and light yellow tibiae.

 as in kilimandjaricus (Tryb.) ; head 1*35 as long as broad 

 and about 1*5 times as long as the prothorax. Postocular 

 and all prothoracic setae long and stout, knobbed. Mouth- 

 cone reaching a little more than halfway across presternum.

 tooth. Posterior margin of fore-wing with seven cilia dupli- 

 cated near apex. Tube 0*6 the length of head ; abdominal 

 bristles long and moderately stout, wing-retaining bristles 

 stout. 



H. harnyi comes nearest to caJiirensis (Tryb.) and hilima-

 developed postocular and prothoracic setae, and in the long
