green, the shade varying in ahnost each larva. Superficially, however, 

 the colour is much the same, and does not vary to a striking 

 extent. On all the specimens there is a distinct purplish or reddish 

 sheen between the segments. The venter in all the specimens is paler 

 than the dorsum. Cervical shield darker than body. Tubercles small, 

 black, normal ; setae pale and slender. Tubercle iv behind the spiracle. 

 Spiracles black, with a pale centre. Feet concolorous with venter ; 

 thoracic feet shiny ; claspers of prolegs blackish. 



Length of mature larva at rest, 35 rnm.; extended, 42 mm.; width 

 at widest part, 5.75 mm. 



On the 13th June four larvae buried, on the 14th two, on the i6th 

 two, and the remaining specimens soon afterwards. Pupation takes place 

 within an earthen cell. 



Pupa. — Average length, 17 mm.; width, 5.5 mm.; colour almost a 

 warm sepia brown, polished ; thorax, wing-cases, etc., finely wrinkled with 

 transverse lines ; abdomen polished, the segments pitted anteriorly. 

 Cremaster stout, darker than abdomen, rugose, excavated beneath, with 

 two slender straight spines, about 0.7 mm. in length, at the tip. These 

 spines are pointed downwards, and are distinctly curved at the end. 



The first moth emerged (in a cool cellar) on the 17th Feb., 1902, 

 and four other specimens emerged on the 12th May, which is the natural 

 time for the imago to appear (Ottawa, April 29, May 4, 7, 10, 21, 23, 

 25, 29, Fletcher, Young, Gibson; Toronto, Ont., May 9, 17, Gibson; 

 Trenton, Ont., May 24, Fletcher; Chats Rapids, Que., May 24, Gibson). 



On the 25th May, 1901, two larvie of this species were found on the 

 common Beaked Hazelnut (Corylus rostrata, Ait. j on the Experimental 

 Farm, and had only emerged from the egg a few days. These were reared 

 to maturity (the larvie being fed solely on this plant), and the caterpillars 

 answered well to those described above, the only apparent difference 

 being that in Stage I the cervical shield was partly margined with black.

The occurrence in Arizona of a lepresentative of a very anomalous 

 wingless genus of Phoridie, of which but a single specimen was heretofore 

 known, and that found beneath a stone in such a widely-separated 

 locality as Denmark, is a problem in geographical distribution very 

 difficult of solution. During the entomological excursion of Messrs. E.
