NEW GENERA AND ^PECIES OF THYSANOPTERA 205 



these intermediate joints is further furnished with a series of 

 bristles or stout hairs encircling it immediately below the 

 swollen part as well as with a few shorter hairs on the con- 

 tracted part near apex. 



Mouth-cone with the labrum long and slender, reaching to 

 base of prosternum ; maxillary palpus with the second joint 

 extremely long and slender, tipped with four hairs. 



ProtJiorax strongly convex, about two-thirds the length of 

 head, widened strongly to base, where it is three times the 

 width of the head at base ; surface smooth and shining. 

 Anterior-marginal and mid-lateral spines wanting ; a com- 

 paratively long spine, however, near each posterior angle. 

 Anterior coxa armed with a similar spine. Pterothorax much 

 longer than broad, wider than prothorax ; metasternum 

 reticulate, laterally rounded, narrowed posteriorly and armed 

 with a single spine at base. Wings reaching to ninth 

 abdominal segment, very strongly fringed. Legs long, 

 posterior and intermediate pairs covered with long stout 

 hairs ; fore-femora much enlarged, smooth, and shining, the 

 outer margin bearing, near base, a few small forwardly 

 directed bristles set in minute warts ; fore-tibia almost 

 cylindrical, armed for the whole length of the inner edge with 

 a double row of small spine-set teeth, set at a slightly forward 

 angle, and tarsus armed with a small tooth. 



Abdomen about one-half the length of the whole insect, 

 as broad as pterothorax, and narrowing smoothly to tube 

 from the seventh segment. Tube scarcely two-thirds the 

 length of head, terminal hairs moderately long. Abdominal 

 spines long and slender, the wing-retaining bristles being 

 more than usually long. Surface very finely reticulate. 



Type — One male (?) in coll. Godman and Salvin. 



Hab. — Guatemala (ex "Salle coll.").
