JUNE 4th, 1908. 



The forty-first re^^nlar meeting was held in the usual place, 

 Mr. Swezey in the chair. 



NOTES AND EXHIBITION OF SPECIMENS. 



Mr. Kirkaldy referred to the notable changes that have taken 

 place in the vicinity of Ivilanea, Hawaii, as a result of the rail- 

 road running through the "Fern Forest." A number of ferns 

 and trees have been killed along both sides of it, and on those 

 dead plants he collected some of the best insects. The making 

 of the road around the crater has also killed a lot of scrub 

 ohias upon which a number of good things, particularly Acu- 

 leate Hymenoptera may be collected. In his opinion the ants 

 had spread farther than their limits in December, 1905. 



Dr. Perkins exhibited his collection of Hawaiian Proterhi- 

 nus ; the collection he said was not nearly complete and com- 

 prised about 120 out of 150 known species. Still it is a fairly 

 good working collection and was carefully examined by all 

 present. 



Further Notes on Melittobia. ha'voa.iiensis Perkins 



BY OTTO H. SWEZEY. 



This little Chalcid was discovered by Mr. Giffard in 1907, 

 bred from the larva of some species of wasp or bee in its nest in 

 decayed branch of tree (Proc. Haw. Ent. Soc, I, Pt. 4, p. 121, 

 1907). In the latter part of the same year, I found several 

 nests of the leaf-cutter bee (MegacJiile pialmarum) in which 

 the most of the cells had been parasitized by this Chalcid. I 

 have reared it in the laboratory also, upon the larvae of three 

 different wasps: Odynenis nifjri'pennis, Pison hospes, and 

 SceJiphron caemenim^di/m. In March. 1908, I first, discovered 

 them breeding on the larvae of the bud-moth (Erennetis fJavis- 

 trinfa Wlsm.) in sugar-cane at the Experiment Station, H. S. 

 P. A. Of a lot of about 50 cocoons of the budworm, collected 

 at one time, 6 of them, or 12%, contained a budworm parasit- 

 ized by Melittobia. Five of them had eggs of Melittohia (7,
