'holesʻin the same situation and at the same date. The larva is 
more closely allied to that of Pterostichus nigrita, figured by 
Schiédte, than any I have seen figured. The body, however, is 
rather slenderer, the head much longer and narrower, and the 
mouth parts longer, while the caudal appendages are shorter. 
The end of the body is like that of Harpalus and Stenolophus as 
figured by Schiddte, but the form of the mandibles is more like that 
of Harpalus. There are no eyes, and the body is white and soft, 
not chitinous as in Carabid larve generally. There is no sculp- 
turing on the head or thoracic segments. 
The larvee of Adelops hirtus has a body somewhat like that of 
Agathidium, but the head is very much larger and as wide and 
long as the prothoracic segments. It is white, and I can perceive 
no eyes. The body tapers rapidly from the prothorax to the end, 
and is provided with long hairs.. The antenne are large and long. 
The larve of these beetles have not yet been discovered in Europe. 
_—A. S. PACKARD, Jr. ; 
New Varrery or Brun Grospeak.—Several Mexican examples 
of G. cerulea examined, uniformly differ from the United States 
bird in the following particulars: they are larger; wing 3°70 in- 
‘stead of 3-40, tail 3-00, as against 2°70; total length about 7-00. 
The bill, in particular, is notably larger every way, and especially 
deeper, with a more swollen upper mandible and more curved ridge. 
‘Length of culmen 0°70, extreme depth about the same; in G. cœ- 
‘Tulea, culmen 0:60, depth decidedly less. It is mostly light brown- 
‘sh horn-color, instead of mostly blackish. I see no difference in 
tie Plumage. This appears to be the resident Mexican form, and 
to be quite as “good” a variety as many of those now current. It 
may be termed G. cærulea var. eurhyncha.—E.uiorr Cours. 
_ Dovorrnism xy Gart Frres.— Mr. H. F. Bassett (Canadian 
Entomologist, v, 91) states that Cynips q. operator is double 
brooded ;. thirty of one brood of females ovipositing in the buds of 
the oak, and again some of a second brood ovipositing in the 
young acorns of Quercus ilicifolia. From these and other facts he 
Jnfers “ that all our species that are found only in the female sex 
“re Tepresented in another generation by both sexes, and that the 
two broods are, owing to seasonal differences, produced from galls 
that are entirely distinct from each other.” This confirms Walsh’s 
discovery of dimorphism in the Cynips (see Amer. Ent. ii, p. 320).
