 Mr. Perkins exhihtcd a collection of insects recently made by 

 Mr. G. P. Wilder on Midway and Laysan Islands. Following 

 is a list of the exhibit : 



LEPIDOPTERA 



Agrotis saiicia. Laysan. 

 A gratis sp? Laysan. 

 Prodenia sp? Midway. 

 Phisia vcrticiUata. Midway. 

 Hymcnia rcciirvalis. Laysan. 

 Pterophorid sp ? Laysan. 



DIPTERA 



A small Acalypterate Muscid. Laysan. 

 A small Tachinid. Midway. 



HYMENOPTERA 



Eiipclmus sp? (Chalcididae.) Laysan. 

 Tciranwrinm guinecnse (Myrmicidae). Laysan. 



NEUROPTERA 



Chrysopa s^i'^ Midway. 



COLEOPTERA 



Thallattodora insignis. Midway. 

 Pcntarthnnn sp ? Midway. 



Mr. Perkins remarked that Mr. Wilder had very little time to 

 collect insects on Midway and practically no time on Laysan. 

 With regard to the species now exhibited, Agrotis saiicia is a very 

 widely destributed and injurious species and is common in the 

 Islands. The second Agrotis is one of the most obscure species of 

 that enormous and most 'difficult genus, and evidently allied to 

 our Island forms. The Prodenia is hardly separable from a Mex- 

 ican species, also exhibited. Hymcnia rccurvalis is one of the 

 commonest Hawaiian moths, and also very numerous in Queens- 

 land and the Malay Islands. The small Pterophorid is also of the 

 commonest Honolulu species. The Acalypterate Muscid is an 

 abundant Honolulu species ; the Tachinid probably identical with 

 one of ours, and parasitic on Plitsia. The Eupchnus is a male 

 unique, and very likely the same as one of our several species. 

 The ant is a cosmopolitan species. The Chrysopa is not like any
