334 ME. R. S. BAGNALL ON TWO NEW 



set tubercles above the mid-lateral angles ; spines at anterior angles and the 

 posterior-marginal and anterior-marginal pairs short and inconspicuous. 

 Each of the prothoracic tubercles, in addition to the chief bristles, is armed 

 with a short seta at the base behind. Fore-coxa with one moderately long 

 and comparatively slender spine. Fore-femur encircled with a series of long 

 and stout spines before apex, a similar series of spines near middle and a very 

 lono- one on the outer edge behind middle. Fore-tarsus with a minute tooth. 

 Hind femora considerably longer than the intermediate pair; both pairs 

 encircled with a series of spines before apex, and armed with one or more 

 strong sjjines at apical third. All tibise furnished with rows of short, slender 

 hairSj but without the long ones below each knee, and each hind tibia armed 

 with a short and stout spine at tip within. Pterothorax much wider than the 

 width across fore-coxa ; metathorax strongly rounded laterally, furnished 

 sparsely with short setse, and armed with one long and stout sub-lateral spine. 

 Metascutum with a pair of erect tubercles, one on each side of mid-line near 

 anterior margin, each armed with a long bristle. Meso- and metascutum 

 rather closely set with numerous short hairs. Wings long and comparatively 

 broad, reaching to the sixth abdominal segment ; cilia rather heavy, and each 

 wing with a very pronounced median vein running for about the entire 

 length. 



Abdomen gradually narrowing from base to tube, and each segment, 

 excepting the ninth, armed with a pair of strong postero-lateral spines ; a 

 single pair of weak wing-retaining spines near the hind miargins of the second 

 to seventh segments ; seventh segment longer than broad, with a deep elongated 

 fovea on each side of the mid-line ; eighth about one-half as long again as 

 broad, with a pair of long and narrow fovea ; ninth segment cylindrical, and 

 only four-fifths as long as broad. Tube very long, nearly ten times as long 

 as its breadth near base, eight times as long as the preceding segmentj and 

 twice as long as the head ; slightly constricted before apex ; surface sparsely 

 covered with rather weak hairs. Terminal bristles short and weak, only 

 about one-quarter the length of tube. Bristles on the ninth segment slender, 

 only about one-third the length of tube ; eighth with a moderately long 

 bristle above the short spine at hind angles and a more slender one on the 

 hind margin within, the other segments with two long bristles above each 

 spine, the sixth and seventh segments having the inner pair of these longer 

 than the outer. 



Habitat. One female, Caracas, Venezuela (Ileinert). 

 Type. In the Copenhagen Museum.
