Neitlier i.s this ctise to lie classed with (hose ius(a:ices of Le])i- 

 (1 )|)terous insects feeding upon dead animal matter; as, hair, wool, 

 hjne, horn or entomological specimens. 



Had a single specimen of this insect hecn observed to be car- 

 niverous 1 should have been inclined to consider this habit an 

 accidental occurranec due to the larva finding itself under unna- 

 tural conditions. Every entomologist knows liow frequently Lepi- 

 dopterous larvae devour each other when imprisoned. In my at- 

 tempts to rear Heliothis «r)niger this season I have been unable 

 to breed more than a single spccinuMi in a jar. 



There are however two insects Avhicli probably resemble in habits 

 to a certain extent Daliri(nia coccidivora. First, Semasia prutn'rora 

 of Walsh- which although it was considered by Mr. Walsh to be a 

 vegetable feeder is found to be carnivorous also by Miss Mary Murt- 

 feldt, who informs me that it feeds upon Coloplui, idmicola Jviley, in 

 great numbers. Miss Murtfeldt is inclined to believe from her observa- 

 tions that the normal habit of the larA'a of this moth is to be preda- 

 ceous and that it was so in the jdaces where found by Mr. '\\'alsli. 



'i^C20\\^, Elide in? nsia hassettella {VAqiw.) ; this species is described in 

 the Proc. Ent. 8oc. Phila., IT, p. i'^o with the statement that the larva 

 feeds in a gall fonnd upon oak. 1 am informed by Prof. Iviley that 

 the supposed gall is in reality a coccid, hence it is probable that the 

 UacJemensia feeds ui)on the eggs of the coccid in the same wnv that 

 DaJiniiii'i cocciiJirom feeds upon the eggs of the Fulrindrid. 



I have l)red over forty specimens of Diil-riimn coccidiconi from 

 Ptdi'iurtrid in)}umc'r(d)ih's. There was no indication of its feeding 

 upon the tree on which it Avas found. Nor was there any evidence 

 Avhatcver that it feeds upon the excretory masses in which it lives. 



Moreover these masses contained in addition to remnants of des- 

 troyed lice and eggs the excrement of the larvae in large ((uanlities, 

 showing that they had resided there for some time. 



These facts I think Avarrant me in considering the species preda- 

 ceous.
