NOTES AND EXHIBITION OF SPECIMENS. 



Mr, Wilder exhibited a male and female and several inflated 

 lar\'ae of Hypocala andreniona ( ?). He discovered the cater- 

 pillar in large numbers on one of his trees on January 11th, 

 of the present year and brought them to the Board's entomolo- 

 gists who could not identify it with anything known to them. 

 Upon further study and subsequent breeding by Messrs. Craw, 

 Kotinsky, Swezey and Jordan it proved to be the above named 

 species. All stages of the insect were observed and parasites 

 (Trichogramma pretiosa) bred from the eggs. Mr. Swezey 

 called attention to the remarkable color variation in the cater- 

 pillars, of which scarcely two were alike, nor was there any 

 apparent relation between colors and sex. Mr. Kotinsky spoke 

 of the peculiar confinement of the insect to a single tree in the 

 vicinity investigated. The identity of the tree could not be 

 ascertained as no flower of it was ever seen. Some insect was 

 known to have injured the tree for the past two or three years, 

 but hitherto undiscovered. 



Dr. Perkins wished to record the presence on these islands 

 of two parasitic Tlymenoptera remarkable for similarity in 

 appearance, yet belonging to what he considers two distinct 

 genera, both of which are new and to be described. Both are 

 common in Honolulu and belong to the family Scelionidae, 

 sub-family Baemae; one or both of them may be parasitic on 

 eggs of foreign Hcteroptera, though from the habits of allied 

 species they would be expected to breed in spiders eggs. The 

 male has 12 antennal segments, the female 7 with a solid club. 

 One of these genera will be named Pseudohaeus, the other 

 Dyscritoljaeus.
