SPONGILLA-FLTES — PARFIN AND GURNEY 443 



Pupae and Cocoons 



he exarate pupa is typically neuropterous, slightly C-shaped, 

 the head and terminal segments of the abdomen bent ventrally 

 6). The antennae usually lie curved over the wings and the legs 

 jo drawn up. The eyes darken first within a day or two after pupa- 

 tii. The pupal mandibles are armed with a broad, blunt tooth on 

 tl inner surface and are more or less symmetrical. 



villington (1936, p. 133) noted that in S.fuscata each of the third 

 t(seventh abdominal segments bears a pair of (latero-) dorsal ridges 

 wh small sclerotized hooks; on the third to fifth segments the hooks 

 Si in double rows. The hooks of the anterior rows are anteriorly 

 dected, while those of the posterior rows are posteriorly directed. 

 Tere are approximately 24 hooks on the third and fourth segments; 



the fifth the two ridges each carry about ten hooks; on the sixth 

 ai seventh segments each ridge usually bears three posteriorly 

 dected hooks, with six (occasionally four) on each segment. On 

 t ; pupae of S. vicaria and C. areolaris examined, hooks are also pres- 

 et, although it was not possible to accurately determine the number. 



1 ere are setae on each side of the hooks. 



A. color pattern appears on some of the pupae and the sexes can 

 b readily distinguished upon examination of the end of the abdomen. 



fn addition to the characters pointed out in the key, the wings of 

 t3 fully developed pupa of Climacia appear longer in proportion to 

 ti width than in the Sisyra specimens examined. 



The cocoons are described on page 429. 



I Key to pupae and cocoons of Sisyra and Climacia 



1 Maxillary palpi with 5th or terminal segment broadly triangular, more than 



twice the width of the 4th; tips of foretarsi barely extending beyond maxillary 

 , palpi; cocoon usually close-woven, frequently appearing almost single- 

 layered (vicaria) (fig. 6, a-c; pi. 3, fig. 6), but sometimes with an outer layer 

 of irregularly and closely spaced open hexagonal mesh, separate from inner 

 layer (fuscata) Sisyra 



2 Maxillary palpi with 5th or terminal segment more cylindrical in shape, narrow, 



less than twice the width of 4th; tips of foretarsi usually extending beyond 



maxillary palpi; cocoon sometimes appearing single-layered, but other 



i times with an outer tentlike layer of a strikingly artistic regularly and 



i widely spaced hexagonal mesh (areolaris) (fig. 6,d-f; pi. 3, fig. 7) . . Climacia 



SpoNnE Hosts of Sisyrid Larvae * 



sFresh-water sponges, which have thus far been reported to serve 

 i hosts for sisyrid larvae, all belong to the family Spongillidae (class 

 esmospongeae, order Haplosclerinae) . These are included in two 



The approved names of the sponges have been obtained from Dr. F. A. Chace, Jr. (USNM), and Mrs. 

 J Q. Benson (Nashville, Tenn.).
