than ill ilispar and nurstiis all the tibiie are annulated near the middle, 

 while in virginicns the annulations are nearer the base of each tibia 

 and more irregular in form, some of the paler hairs extending to the 

 basal part of the tibit on its inner side. 



From })iixtiis and ma^stus, P. z'irgi>nciis differs so greatly in the 

 form of antennae that there is no risk of confusion. The anteimie of 

 P. dispar ^ are one half longer than body (not one half the length of 

 the body as erroneously stated in " Rhynchophora of N. E. Amer- 

 ica") and it is possible that the male of virgiuicus has also antennae 

 longer than the body. 



NOTES ON THE OVIPOSITION OF SOME SEMI- 

 AQUATIC HEMIPTERA (HEBRUS, SALDA, 

 LAMPROCANTHIA).

In 191 1 the late Doctor Heidemann published "Some Remarks 

 on the Eggs of North American Species of Hemiptera Heteroptera,"^ 

 in which he listed the eggs of the Hebrids, Saldidce and Mesoveliidse 

 as unknown. Since that time Renter in his " Neue Beitrage zur 

 Phylogenie und Systematik der Meriden, nebst einleitenden Bemer- 

 kungen fiber die Phylogenie der heteropteren Familien, 1910" at- 

 tempted to show the phylogenetic relationships of the families of heter- 

 optera. In 1912 he modified his system in the light of added evidence. 

 It is in his '' Bemerkungen fiber mein neues Heteropteran System, 

 1912" that he quotes Bergroth to the effect that Bueno had examined 

 the egg of Mesovelia and established its great similarity to the Na- 

 bidae. Since that time the writer has figured and described the egg of 

 Mesovelia mulsanti, White. 



In reviewing Kirkaldy's splendid papers on British water bugs, 

 1894-1908, Wesenberg-Lund's " Fortpflanzungsverhaltnisse : Paarung 

 und Eiablage der Siisswasserinsekten," as well as such texts as Bade, 

 '09, Brauer, '09, Ulmer, '11, and Brocher, '13, it would appear that 

 the egg stages of Hebrids and Saldids are as vet unnoted.
