Woodpeckers are among the eiieniies of H. abietis. The larvae 

 are parasitised by a Braconid and an Ichneumonid, Ephialtes tiibercu- 

 htus, and the pupae by au imidentified Ichneumonid. An eelworm 

 {TylencJioniorphus sp.) is parasitic on the larva, and in some districts 

 a bacterial disease destroys numbers of larvae. Most of the informa- 

 tion given on Pissodes pini and P. notatus has been noticed above.

This paper deals with moths that have been reared in connection 

 with the forest insect investigations of the U.S. Bureau of Entomology. 

 A new genus, Tosca, is erected and sixteen new species and two new 

 varieties are described. 



Among the new species are : Wnjacionia (Evetria) ulteriorana reared 

 from cones of Pseudotsuga taxifolia ; R. luculentana from Pinus 

 scopulorum, the larvae inhabiting pitch nodules and feeding on 

 terminals of branches ; Eucosma rescissoriana from cones of Pinus 

 murrayana ; E. monitorana from cones of Pinus ; E. tocullionana from 

 cones of Picea ; Cydia (Laspeyresia) -pallidihasalis from cones of Abies 

 concolor ; Gelechia negundella from Acer negimdo ; Recurvaria moreonella 

 from Pinus scopulorum ; Tosca plutonella, a leaf-miner on Prunus ; 

 and Holcocera augusti from cones of Pseudotsuga taxifolia.

 Amelanchier canadensis ; P. plesia, on Populus tremuloides ; Pristi- 

 phora betulavora, on white birch {Betula alba) ; Ichneumonidae: 

 Lissonota evetriae, parasitic on Rhyacionia (Evetria) taxifoliella ; 

 L. dioryctriae, parasitic on Dioryctria xantluienobares ; Exochus 

 evetriae, a pupal parasite of i2. [E.) taxifoliella and R. (E.) siskiyouana; 

 Mesoleius gymnonychi, a parasi e of Gymnonychus californicu < ; 

 ■Exenterus affinis parasitic on cocoons of Neodiprion sp. feeding on 

 Pinus resinosa ; Braconidae : Microfypus dioryctriae, parasitic on 

 Dioryctria xanthaenobares. 



A key is given to the North American species of the genus Exenterus^ 

 lin which the author includes the species formerly placed in Picroscopus.
