52 ENTOMOLOGICAL NEWS. [Feb., 'l6 



It is possible that Lopidea robiniae is two-brooded, at least 

 in New York State. Mr. H. H. Knight has kindly informed 

 me that during 1915 at Wyoming, New York, most of the 

 nymphs had matured by the latter part of July. No specimens 

 were again taken until August 12, when 8 adults and 3 fifth- 

 stage nymphs were collected on locust. These were appar- 

 ently stragglers from the first brood. Although constant search 

 was made for Lopidea robiniae no more specimens were 

 found until September 14 at Wyoming, when adults were very 

 abundant. Five or six fifth-stage nymphs were collected and 

 about 163 adults, many of which were teneral. 



If the species is one-brooded it is possible that the excep- 

 tionally cool, rainy weather which prevailed throughout west- 

 ern New York during; June and July, 1915, delayed the hatch- 

 ing of many of the over-wintering eggs until the early part of 

 August. This would give the nymphs about a month to pro- 

 duce such a large number of adults as was found by Mr. 

 Knight on September 14. 



The foliage of the trees on which the nymphs were most 

 abundant was injured to a considerable extent by a character- 

 istic yellow stippling and sometimes in addition the leaves were 

 crumpled. When feeding, the nymphs remained mostly on 

 the under side of the leaves. 



Stage I (Fig. i). Length, 1.35 mm.; greatest width of abdomen 

 .576 mm. Head pinkish, a whitish, rather indefinite procurved line on 

 vertex connecting the eyes. Each thoracic segment with two dusky

 thorax, whitish; whole of metathorax, median line on thorax and 

 behind spots on the two thoracic segments, tomato red. Abdomen

 second and a rather indefinite spot on lateral margin of segments 3-6 

 inclusive, white. Opening of dorsal gland indicated by a dusky spot. 

 Antennae reddish, paler at joints; terminal segment covered with fine 

 golden hairs; other segments more sparsely clothed with longer dark 

 hairs. Legs pale brownish, tarsi dusky. Dorsum sparsely clothed
