The adult females work diligently manipulating the larvae 

 for food, but they are not able thus to feed themselves as 

 the Scleroderml can, but require other food. It has been 

 necessary for me in working with them to feed them with 

 honey in order to keep them alive. 



Two males of this species were taken on my office win- 

 dows and one of these placed with a very large female soon 

 mated with her and mating was repeated several times,

H. HOSPES. 



There has always been some difficulty on my part in dis- 

 tinguishing between these species from the descriptions. 

 I have therefore drawn up a summary of the characters by 

 which the females may be distinguished. 



I have never seen a nuile of //. hospes. 



Holepyris haiuaiiensis (Ashmead), Smaller; antennae dusky at tip; 

 punctures of head finer ; submedian ridges of propodeum nearer the 

 median, more distinct and shorter ; the area lateral to them more fivjel^v 

 striate anteriorh- and more coarsely posteriorly. 



Holypyris hospes Perkins. Larger; antennae not dusky at tip; 

 punctures of head larger and more distinct ; submedian ridges of pro- 

 podeum farther from the median, less distinct ; lateral areas more 

 evenly and fineh' striate.

The insect fauna of the lowlands of the Hawaiian Islands 

 is now made up largely of immigrant forms brought in 

 through the operations of commerce. With the advent of 

 the European and Asiatic races in the islands and the in- 

 troduction of the cultivated plants and weeds and the develop- 

 ment of herds of cattle the native vegetation began to dis- 

 appear from the lowlands, surviving only on some of the
