ami placed with the Sclerodo-iiius in clean, fresh tubes. By 

 Oct. lo tv.-enty of the lifty maggots had pupated and the re- 

 uiaining larvae were more or less collapsed and dried up wLtli- 

 eut any positive indication of their having been fed upon by 

 the >''^cl erode rums. When some of the puparia were opened up 

 the Sclerodeniiiis female at once attacked them and fed upon 

 the pupa freely and in one instance a Sclci-odcrinus was seen 

 anawing away around the anal pit of the Sarcophacja pu- 

 ]iariiiin in the effort to enter. 



The kiuds of prey actually known to be utilized in the 

 field are the Bruchid, the two Bostrj-chids, and the Cerambycid 

 larvae excepting the Xysirocera. It is evident that several 

 things tend to limit them in actual practise: (1) The adult 

 Sch'rodermi like to frequent dead and seasoning or rotten 

 wood and practically confine their visits there. The pods of 

 Acacia farnesiana- in which Caryohorus was found attacked is 

 only an apparent exception. In its properties it is near enough 

 like tlie wood and is found attached to the bushes. (2) Other- 

 wise available prey may be able to destroy the females. (3) 

 Some of the prey may not keep in condition for larval food 

 long enough for them to reach full growth. (4) The termites 

 and ants would not usually be attacked because entrance to the 

 nests would be successfully resisted. 



Prey of the Endemic Species. The endemic species of 

 Sclerodermiis have until 1919 always been found in ass(X'ia- 

 tion with wood-boring larvae of moths related to Ilyposmo- 

 coriKi. Sciinwprepia, and Hyperdasys. but in August, 1919, 

 Mr. Swezey secured material of S. miiiri Bridwell from Kona, 

 Hawaii, above Kealakekua in wood of Straussiay where it was 

 taken from the borings of an Anobiid beetle upon the larvae 

 of which they had evidently bred. The material consisted of 

 two masses of cocoons of three and five front wliich three and 

 four apterous females emerged respectively. Repeated ex- 

 amination of material in the mountains near Honolulu has 

 disclosed but little indicaliou of use l)y any of the ciKh'Uiic
