WITH DESCRIPTION OF A NEW GKNUS 



OF THYSANOPTERA 



By Ifiiclinrtri^. IBngiiall 



When several authors write on Lhe same group, independently 

 and at the same time, it is only to be expected Ihat a certain amount 

 of over-lapping will occiir. This is the case willi tlic Ordei* Thysano- 

 ptera, which, until comparatively récent years, lias been so little 

 studied, and thèse notes relate chiefly to some recenlly pablished 

 papers by Dr. Pietro Buffa, Rome, and the présent wriler. 



At the end is a Ust of références, arranged alphabetically and 

 numbered consecutively, the numbers iised hereafter referring to 

 this list. 



Family PHLŒOTHRIPID/E 



Genus EGAGANTHOTIIRIPS nov. 

 Type E. (AcanthothripsJ sanguineus Bagnall (I), p. 262, pi. XV, 

 fig. 15. 



Since I described ■AcantlwUirips sanguineus, which I placed 

 provisionally in the genus Acanthothrips Uzicl, I liave had the 

 opportunity of studying tlie single European species A. nodicovnis 

 (Heuter), and the American species A. magnafcnioralis IIixds, 

 A. Doaneii Moulton and A. albiviltatus Hood, and it is now quile 

 clear to me that A. sanguineus does not naturally fall into this 

 genus, but possesses characters of distinct generic value. For the 

 réception of the single species I would propose tiie new genus 

 Ec acanthothrips. 



Head longer than broad, cheeks with spine-beai'ing warts. 

 AntenuEe twice as long as head, interuiediate joints elongate and 

 possessing sense-cones more than usually long; third antennal 

 joint broadly obconical. 



Surface of prothorax granulate. Fore-femur enlarged and some- 

 what flattened, without teeth at apex within, but each furnished with 

 a long, sliarp, and slightly curved tooth from the base within. 

 Fore-tarsus armed with a stout tooth. Wings présent. 



Maie apparently without scale at base of tube. 



This genus may at once be recognized by the long and slightly 

 curved tooth near the base of each fore-femur within, and by the 

 broad, obconical form of the third antennal joint.
