 Notes on "Crocidosemamarcidelluin" (Walsm.) [Tortricidae], 



BY OTTO ir. SWEZEY, 



This species was described by Lord Walsiiighain from a sin- 

 gle female collected by Perkins in the Waianae Mountains in 

 1892, and provisionally placed in the genus Adenoneura — the 

 absence of the male making it impossible to determine the genus 

 with certainty. I have recently reared a series of 3-1 specimens, 

 and find that the species belongs in the genus Crocidosema, the 

 male having the characters distinguishing that genus. There is 

 some variation in intensity of markings in my series, but many 

 of them exactly match the figure given by Walsingham in the 

 Fauna Hawaiiensis. 



]\[y series of specimens were all reared from larvae in fruits 

 of the native Hibiscus {H. arnottianus) collected from a tree 

 along the Manoa Cliffs Trail of Mt. Tantalus, March 15th, 

 1014. It was the first time that I ever found fruits on a tree 

 of the native Hibiscus, and I noticed that they were much eaten, 

 so took along about two dozen of them (about all that I could 

 conveniently obtain) to rear the moth from the numerous larvae 

 infesting them. My 34 specimens emerged April 3rd to the IGth. 



Mr. J. F. Eock told me once that he had found the fruits 

 of this Hibiscus and other related trees in the mountains of Ha- 

 waii badly eaten by insects. I have no doubt but what they were 

 the larvae of this moth. 



The eggs of the moth are laid on the outside of the enclosing- 

 calyx. On hatching the young larva eats through this, and feeds 

 for a time between it and the fruit, finally eating inside of the 

 fruit and destroying all of the seeds. In the lot of fruits that I 

 collected there were but three seeds remaining uninjured when 

 the larvae had finished with them. 



The young larvae have the head and cervical shield black. 

 The full-grown larva is about 12mm. in length, dirty whitish or 

 yellowish with a rosy tinge ; head very pale testaceous, eyes 

 black, a black streak behind eyes and above this the posterior 

 margin of the head is black ; cervical shield concolorous, two 

 submedian blackish spots at posterior margin ; spiracles circular, 

 black margined ; surface of body minutely roughened except cir- 

 cular areas at base of setae. 



The pupa is about 7mm. in length ; yellowish brown ; wing-
