(Brit. Mus. Hemip. Insects, i. 2, 1851-1852, p. 538) from a descrip- 

 tion drawn up by Herrich-Schaffer who apparently misidentified 

 Fabricius's anlicus (Wanzenartigen Insecten, 1842, Band VI-IX, pp. 

 7^77). Dallas (loc. cit.) in addition to the United States, lists 

 specimens as having been received from Mexico, Brazil. Colombia 

 :>.nd British Guiana. Van Duzee in his check list gives numerous 

 references to the species and the localities listed indicate a wide 

 distribution in the United States. 



Lygaeus kalmii Stal. (Hemip.). 



In Ent. Amer., Vol. Ill, p. 53, 1887, Townsend under the name 

 Lygccus turcicns Fab., calls attention to the early papers dealing with 

 the feeding habits of this species and notes his own observations on 

 this insect in Michigan. He states that it is common on A. tuhcrosa 

 and sometimes on A. syriaca, being found from June to September 

 and that it probably hibernates as an adult. He speaks of obtaining 

 from 6 to 35 eggs from various females. In New Jersey, Lygccus 

 kalmii occurs throughout the State from April to October, on several 

 species of milkweeds. 



Agromyza pusilla Mg. (Dip.). 



The milkweed leaf miner Agromyza pitsiUa Mg., is a common 

 species throughout New Jersey especially on Asclcpias syriaca. The 

 mines consist of irregular, whitishi blotches on the upper leaf sur- 

 face. Sometimes the mines run together forming a large blotch, 

 which takes up a considerable ])ortion of- one half of the leaf. As a 

 rule, the mines start between the side veins and some often have 

 two parallel sides due to the failure of the larva to mine beyond the 

 veins. The number of mines in a leaf varies from one to several. 

 When full grown the larvae leave the mines and fall to the ground 

 where they pupate in soil cracks, under leaves, etc. There are several 

 generations in New Jersey and larv?e can be found almost any time 

 from the middle of May to the middle of September. Asclcpias 

 pulchra leaves were not mined to the same extent as those of 

 Asclepia's syriaca and in pulchra the edges of the mined area were 

 somewhat reddish. It was noted that almost any kind of insect 

 injury to pulchra resulted in reddish discolorations around the in- 

 jured portions. 



There are several accounts of this species in European literature.
