March, 19 18.] HUNGERFORD : OviPOSITION OF HeMIPTERA. 17 



Nymph of S. anthracina. 



When this species was first taken all the specimens were in the 

 last and next to last instar. The nymphs are somewhat more flattened 

 than the adults. The antennal segments are thicker in proportion to 

 their length and the eyes much less protuberant. Ocelli are lacking 

 in the nymph while the adult possesses a pair of prominent ones. The 

 tarsi are two-segmented in the nymph, three in the adult. Secondary 

 sexual characters not apparent in the nymph. 



Egg of Lampracanthia crassicornis Uhl. 



Size. — Length i mm., diameter .3 mm. 



Shape. — Elongate cylindrical. Both ends bluntly pointed, one 

 more than the other and curved upward. Camera-lucida drawings of 

 the eggs of both species are shown drawn to the same scale on PL 



. figs. 7 and II. 



Summary. 



Hchrus concinnns, Salda anthracina, and LainpracaiitJiia crassi- 

 cornis were found about the moss and clumps of shore grasses bor- 

 dering a swampy pasture pool in New York. All three bugs hide 

 their eggs between the leaves of the moss. The Saldids often place 

 their eggs at the bases of the grasses growing on the moist banks of 

 the pool. L. crassicornis appeared as adults some ten days before 

 S. anthracina. 



The Hebrids are but little disturbed by close confinement and the 

 Saldids can be kept in the laboratory if provided proper quarters. 



These few notes are submitted at this time in view of the need for 

 even meager information concerning the shore bugs herein discussed.
