PROCEEDINGS OF THE NEW YORK ENTO- 

 MOLOGICAL SOCIETY. 



Meeting of May 16, 1905. 



{Continued from Vol. XIV, p. 112.) 



Mr. Roberts made some remarks on the HaliplicL-e and exhibited his collection 

 in this family. He stated among other things that this family had been in more or 

 less confusion for years and no good structural characters had been found to differen- 

 tiate the species or to separate the males from the females. After considerable inves- 

 tigation he had noted that there was great variance in the shape and character of the 

 prosternal process in the different species and also in the males the second and third 

 joints of the front tarsi were enlarged or flattened and these joints were in some cases 

 lobed, excavated or tuberculated while in the females these joints were simple. ' He 

 had found that the shape of the coxal plates was to be depended upon as a good char- 

 acter in connection with the sexual characters referred to above. He briefly spoke of 

 the distinguishing characters of several species and discussed their habits. 



Mr. Davis exhibited several interesting insects chiefly Orthoptera from the Pine 

 Barrens of New Jersey among which were : Conocephahis caudellianus Davis taken 

 in an overgrown cranberry bog and closely resembling C. robustus; Conocephahis 

 nebrascensis Bruner which is not in Smith's List of New Jersey Insects and, so far as 

 he was aware, has never been reported east of the Mississippi Valley ; Orchelimum 

 erythrocephalum Davis which resembles O. vtdgare but having a very red face and 

 head ; Ophiogomphus joh annus Needham, a dragon-fly, new to the List of New Jer- 

 sey Insects, collected at Hewitt, N. Y., in June; Ophiogomphus rupinsulensis collected 

 in Northern New Jersey near Suffern, N. Y. ; Axion tripustulatum, a coccinelid beetle 

 found at Lakehurst, N. J., on post oaks (Quercus minor) that had been attacked 

 by the scale insect Kermes pubescens. This scale insect seemed to be also an addition 

 to the New Jersey List.
