spending their immature stages in this habitat, where they are associated 

 with a remarkable fauna of other organisms. The adult females hav.e 

 the valves of the ovipositor greatly elongated, and the writer has sug- 

 gested elsewhere that this may be an adaptation for laying the eggs in 

 this habitat. T. bromeliadicola was reared in Costa Rica by Picado, 

 whose important paper (Picado, 1913) on the bromeliaceous epiphytes 

 contains colored figures of the larva, the pupa, and the adult. From 

 this paper it is seen that the larva (page 356, figure A, and plate 13, 

 figure 4, of reference cited) is not unlike that of T. pennipes, described 

 above, the four prominent anal gills of T. bromeliadicola (Plate LXXVIII, 

 420, of this paper) being a notable feature in common, altho here the 

 constrictions are very numerous, there being twenty-five or thirty shown 

 in the figure. The pupa (Picado, 1913:357, fig. 51, and pi. 13, fig. 2) 

 has the pronotal breathing horns (Plate LXXVIII, 421, of this paper) 

 approximated on the median line, and the sheaths of the ovipositor (Plate 

 LXXVIII, 423) greatly elongated to contain the elongated terebra of the 

 adult within. According to Keilin (1913), the tegumentary glands of this 

 larva are a provision against drought, which is the great source of danger 

 to organisms living in this habitat. 



Trentepohlia (Paramongoma) leucoxena (Alex.) 



1915 Mongoma leucoxena Alex. Ent. News, vol. 26, p. 29-30. 



Trentepohlia leucoxena was reared by Knab in Mexico, from larvae 

 found living in bromeliaceous plants quite as in the preceding species. 



Genus Teucholabis Osten Sacken (Gr. weapons + forceps) 

 1859 Teucholabis 0. S. Proc. Acad. Nat. Sci. Phila., p. 222. 



Larva. Form elongate, slender, terete. Body practically destitute of pubescence and 

 setae. Spiracular disk surrounded by three very broad lobes, a flattened ventral lobe and 

 two shorter lateral lobes at the base of which are the small black spiracles. Gills four, 

 bluntly rounded and developed for propulsion. Head capsule of four elongate, slender rods 

 or plates, interno-lateral pair forked at about midlength. Mandible rather small, with about 

 three blunt lateral teeth. Antenna elongate, two-segmented. 



Pupa.- Cephalic crest setiferous. Pronotal breathing horns short, blunt, closely applied 

 to thorax. Mesonotum precipitous, at crest with two powerful hooks and smaller serrated 

 plates near shoulder. Wing sheaths reaching end of second abdominal segment. Leg 

 sheaths reaching end of fourth abdominal segment, middle tarsi the shortest. Abdomen 

 with a transverse row of setae before ends of segments.
