Chalcolepidius erythroloma. — Mr. Swezey exhibited an ap- 

 parently nearly fnll-grown larva of this large Elaterid beetle 

 which he had fonnd in a dead, partially rotten tree trnnk of 

 Maba sandwicensis on Niu Ridge, February 10th, 1918. There 

 were termites and lepidopterous larvae in the same tree. Some 

 of the termites were placed in a tin box with the beetle larva 

 and after a day or two were fonnd to have all been eaten. Since 

 then, it has been fed with the larvae of Adoreius, eating two 

 or three daily. Thus the predacious habit of this Elaterid is 

 proven. 



Capua n. sp. — Mr. Swezey exhibited 6 specimens of a 

 Tortricid moth reared from larvae found on the leaves of 

 Reynoldsia sandwicensis in Niu Valley, February 10th, 3 918, 

 which is an undescribed species not previously collected. 



Tliecla echimi. — A specimen of this butterfly was exhibited 

 by Mr. Swezey, bred on egg-plant. The larvae were found on 

 the leaves and in the fruit, February 5th. Three butterflies 

 were reared from the material gathered. The species is one of 

 the two species of butterflies introduced from Mexico to feed on 

 Lantana. In 1908, Kotinsky reported having bred one of these 

 butterflies from pepper pods (Proc. Haw. Ent. Soc. II, p. 36, 

 1909). It may possibly have been this species. 



Nesosydne lealii. — Mr. Giffard reported that he and Mr. 

 Fullaway in collecting on Diamond Head slopes, February 

 24th, 1918, had discovered the macropterous form of this Del- 

 phacid. 



California Hemiptera. — Mr. Giffard exhibited a collection 

 of Central Californian Homoptera and Heteroptera made by 

 him during the summers of 1916 and 1917, and determined 

 and catalogued by Mr. E. P. Van Duzee in the Proceedings 

 of the California Academy of Sciences, 4th series. Vol. II, 

 T^o. 11, pp. 249-318, Dec. 31, 1917. The collection enumer- 

 ates 355 species in all, including a few forms taken by Mr. Gif-
