larva of that species. At that time it measured probably about 6 mm. in 

 length, and I thought that possibly it might soon pupate. This it failed 

 to do, however, but continued to work in the piece of branch all summer. 

 Wishing to determine whether this larvae was still alive at the end of the 

 year 1 followed up its burrow on Dec. 30, 1907, and soon located it. It 

 was apparently thriving, although it had been in the dry branch in a hot 

 laboratory all summer, and had increased somewhat in size, I have made 

 no search for it since, but have hopes that eventually I may find a 

 specimen at A.fallax in the cylinder. 



This species has been recorded as affecting the locust {Robinia 

 p send acacia), but! have seen no reference to its occurrence in Gleditschia. 

 Chittenden states that the habits of A. fallax are similar to those of A. 

 egejius, and of the latter species he says : 'Tnfests locust {Robinia 

 pseudacacia), mining under the bark and twigs of the smaller branches, 

 the beetles eating the leaves." In further notes o\\ A. fallcix\\^ says: 

 'Tn the National collection is a series from Central Missouri, labelled by 

 Dr. Lugger on locust, and another series from Iowa similarly labelled by 

 the la'e Dr. C. V. Riley. Among Divisional notes is one of the occur- 

 rence of what is stated to be this species under the bark of cottonwood, 

 in July.^ 



Hopkins^ states that this species "infests bark and wood of dying 

 branches on living and dying Hackberry," and that adults were taken May 

 2 in Wood Co., W. Va. 



Packard,' in his ' Forest Insects," does not mention any species of 

 wood-boring beetles as affecting the honey locust, but gives a list of 

 several species of insects that feed upon its leaves. With but three 

 exceptions, these are all Lepidoptera, the exceptions being Lytta ( Epicaida) 

 cinerea, Forst., Eburia 4-gennnaia, Say. and Spei'mophagus 7-obi?iice, Sch. 

 (The last in seeds.) 



I have found the following beetles, which were presumably feeding 

 to some extent upon the leaves, upon this plant : Anomoea laticlavia, 

 Forst.; Nodonota puncticoUis, Say ; Macrobasis unicolor, Kirby. Other 

 species that I have taken thereon, but whose presence was probably 

 merely accidental, are the following : Photuris Pen?isylvn?iicus, De Geer; 

 ChaiiliognaiJius marginattis, Fabr. ; Statira gagatina, Melsh.; Mordel- 

 listena pusinlata^ Melsh.
