398 Dr. J. L. Leconte's Synonymical Notes 
20. H. ochropus, Kirby, seems to be the species afterwards 
described as H. fulvilabris, Mann. 
21. Peryphus concolor, Kirby, is a very distinct and well- 
defined species; the prothorax is quadrate, slightly Kreis 
behind; the basal i impressions are distinctly double; the e 
D strim are strongly punctured and nearly effaced ee 
the tip. 
22. P. sordidus, Kirby, is merely an immature specimen 
of P. bimaculatus, Kirb 
23. Laccophilus biguttatus, Kirby, is an immature specimen 
of our common small species, L. proximus, Say, —americanus, 
Aubé. 
24. Necrophorus obscurus, Kirby. This is the species, aliod 
to N. MASA which I erroneously determined as N. Mels 
` heimeri, Kir 
M N. Melsheimeri, Kirby, =Sayi, Laporte, = lunatus, 
^0. N. hebes, Kirby, is evidently one of the varieties of the. 
ee afterwards described, from Alaska, as N. maritimus, 
ann. 
27. N. pygmzeus, Kirby, seems to be an unusually small 
specimen of N. defodiens, Mann. The form of the prothorax 
is a character of -great importance in the grouping of the spe- 
cies of this genus, but was unfortunately not described by 
. Kirby with sufficient minuteness to permit his species to 
be properly referred without inspection of the types; on the 
other hand, the form and size of the rhinarium, upon which, 
with very small series of specimens, he laid great stress, is of 
no specific value 
28. Cry arse p concolor, Kirby, belongs to Frp 
and was fe in described as T. ruficornis, Lec 
29. C. humeralis, Kirby, is merely a paler specimen of the 
same species. 
30. Attagenus cylindricus, Kirby, is a very elongate species 
with the prothorax densely punctured; it is quite distinct 
from any other known to me. 
31. Byrrhus concolor, Kirby, is a species of Cytilus which 
differs from the American form of C. vari us (alternatus, Say) 
ee scutellum being clothed with black, garter of golden, 
32. B. picipes, Kirby, is the same species afterwards de- 
scribed as B. geminatus, Lec. B. Kirbyi, Lec., is much more 
robust and more obtuse behind. 
33. T. mandibularis, Kirby, is T. fraxini, Say.
