EXPLANATION OF THE PLATES. 339 



IG. L^imnobia solitakia 0. S. ; forceps from above, half closed; ua 

 are coriaceous, movable ; bb. hooked appeudages, consisting of two, 

 closely applied lamels ; the outer one horny ; the inner one appa- 

 rently coriaceous ; e. the anal style ; cc. projecting internal organs ; 

 lb. soft eminences (perhaps rudiments of the large soft lobes of 

 Dicranomyia). 



•y. Limiiobia indigena 0. S. ; forceps from above ; the lamels bb are 

 double. 



8. Elepliantoiuyia westwoodi 0. S. ; one-half of the forceps ; aa. 



horny appendages. 



9. TeuchoBabis complexa 0. S. ; forceps from above ; 9a. one- half 



of the same, from below ; aa, bb. horny appeudages. 



10. Antocha saxicola O. S. ; forceps from above ; aa. double append- 



ages, consisting of a horny and of a soft part, closely joined. 



11. Dicraiioptyclia nigkipes 0. S. ; forceps from above ; y. short, 



black bristles ; xx. indistinct horny appendages. When this species 

 opened its forceps, a delicate, horny apparatus (figured separately, 

 fig. 11a) was spread outside of it; bb is a slender forceps, moving 

 independently of aa, and closing at the point c. 



12. Dicranoptycha sobrina 0. S. ; one-half of the forceps. 



13. Crypt olabis paeadoxa 0. S. ; forceps from above. 



13a. the same from below ; aa. horny appendages, small and indis- 

 tinct, being closely applied to the fleshy part of the forceps ; 

 6 seems to be the rudiment of an anal style. 



136. the tip of the abdomen of the female, from the side. 



13c. the same from above ; both show that there are no visible horny 

 lamels ; the prominences aa are beset with microscopic bristles. 



PLATE lY. 



14. Erioptera aemata 0. S. -, forceps from above. 



14a. the same, from the side ; its structure is somewhat complicated ; 

 besides the coriaceous parts, dd, there are two pairs of horny 

 appendages ; one of them is seen at h, in fig. lAa ; when de- 

 tached, it looks like fig. 146, in which the portion 666 is closely 

 applied to the coriaceous part d and c branches off. The other 

 pair of appendages, ee, of fig. 14a, is slender and curved. 



15. Erioptera caloptera Say; forceps from below. 



16. Erioptera venusta 0. S.; forceps from above. 



16a. the same, from below; the horny appendages, aa, seen from 

 below, appear-double, consisting of the horny part, 66, and the 

 membranaceous appendage, cc ; fig. 166 represents it detached ; 

 its margin d is horny, the rest is membranaceous ; these two 

 appendages have an interval between them, although they 

 move simultaneously.
