NEW GENERA AND SPECIES OF THYSANOPTERA 203 



swollen. JViiigs reaching beyond apex of tube, brown in 

 colour, coriaceous and heavily fringed. 



Abdomen apparently ovate and wider than the pterothorax, 

 with moderately long spines. 



Type — One specimen in coll. Godman and Salvin. 



Hab.— Orizaba (H.S. & F.D.G., Dec, 18S7). 



Genus EUPATHITHRIPS* nov. 



ZT^^^ about one and one-half times the length of prothorax, 

 and more than three times as long as the width at base. 

 Cheeks slightly swollen, set with a lateral series of small spine- 

 set warts. Eyes large and prominent. Ocelli rather large, 

 and set on a slight elevation. Antennce longer than head. 

 Sense-cones extremely long and acute, each protected by a 

 long and slender bristle or accessory cone, the joints bearing 

 these organs being much swollen. Mouih-cone long and 

 slender, reaching to base of prosternum. 



Base of prothorax nearly three times as wide as the head 

 at base, strongly narrowed to anterior margin. Fore-cox(Z 

 prominent, and each armed with one conspicuous spine ; 

 femora long and swollen, and each tibia with a double row of 

 small teeth on the inner edge ; tarsus armed with a small tooth. 

 Wings present. Intermediate and posterior legs rather long 

 and slender. Abdomen slightly broader than prothorax, with 

 abdominal spines more than usually long. 



Species of medium size. 



Type — Enpathithrips dentipes mihi. 



This genus is at once distinguished by the highly developed 

 antennal organs, and further differs from any other described 

 form of Thysanoptera in the character of the anterior tibiae, 

 each of which is armed with a double row of small teeth for 

 the whole length of the inner margin. The mouth characters 

 agree to a remarkable extent with those of Poecilothrips Uzel 

 (type P. albopicta Uzel) ; otherwise the species is of a some- 

 what anomalous character, and must only be regarded as 

 belonging to the Phlxothripidce provisionally. 

 * Eupathi- =:very sensitive.
