The cocoons require about two tiays for coiistnierioii am! 

 are bnilt in a fairly compact mass iu the vicinity of the prey 

 npon which the larvae have fed. This has ordinarily been al- 

 most completely consumed by the larvae and their mother. 



As has been previously recorded, the mother feeds Avith 

 the larvae and on occasions when the prey deteriorates before 

 the larvae are full-grown she may resort to cannibalism, feed- 

 ing- npon her eggs or larvae. In one instance tw^o larvae were 

 found feeding upon one of their own kind w^hicli had perished 

 on account of the deterioration of their food. 



The f':'male does not pierce the skin of her prey with her 

 mandibles but apparently forces the juices out through the 

 cuticle with her mandibles. She later feeds upon the juices 

 exuding fvom the wounds made by the larvae. I have not 

 been al)le to discover any certain evidence of any kind of ma- 

 ternal assistance to the larvae. *• 



12. SCT.ERODERMUS ImMIGRANS, AN lM:\rTCTRA XT FRO^r THE 



Philippine Islands. 



This species was taken originally from the cocoons of the 

 HrwehidjC aryhoru.^ (fwiar/ra. in the pods of Acacia farnesiana 

 on the island of Oahu. In describing the species it was said 

 to be in all probability an immigrant into the Hawaiian Isl- 

 ands. This belief has been confirmed since a female collected 

 by Dr. F X. Williams at Los Banos, Luzon, Philippine 

 Islands, nov; in the collection of the Hawaiian Sugar Planters' 

 Association proves to belong to this species. Dr. Williams 

 informs me that the species is not uncommon there and is 

 semidomestic, being associated with Bostrychid beetle larvae 

 in the houses.

Several small Scolytidae of the genus nypotlienemus and 

 its allies have been described from the Hawaiian Islands, are 

 numerous in individuals but at present we have but little
