Abutiloneus Bridwell 
The differentiation of Abutiloneus from Sparteus in Brid- 
well’s 1946 key is not entirely satisfactory. Sparteus villosus 
may have a minute angulation on the inner margin of the hind 
tibiae, as stated by Bridwell but it may also have two denticles, 
and sometimes apparently none. A specimen in the Fall collec- 
tion determined as flavicornis Sharp^from San Diego, Texas, 
collected by E. A. Schwar/z and evidently of the lot referred to 
by Schaeffer in 1907, has denticles or granulations under the 
femora, and species that I have considered congeneric have each 
2 small equal denticles. Neither does the length of the elytral 
striae entirely serve, as there is considerable difference among 
these species in that regard. One can say however of Sparteus 
that striae 3 and 6 are equally long, approach one another at 
apex and are much longer than 4 and 5, 6 curving in close to the 
apex of 5, but than in Abutiloneus this is not the case, though 
approached in atomus Fall. 
Merobruchus Bridwell, 1946 
Merobruchus major (Fall) new combination. The type of 
this species shows clearly that it is a Merobruchus.

In the foregoing paragraphs attention has been drawn to a 
number of genera and generic transfers that should have been 
recorded in the supplements to Leng’s Catalogue. While the 
cataloguers cannot be excused for their omission, it is only fair 
to lay a considerable portion of the blame upon the authors in- 
volved, for in many instances the transfers have been made in 
a way that failed to direct attention to them, or to the fact that 
North American insects were involved. In one instance generic 
transfers of North American species were made, and thereby a 
genus added to the North American fauna in a paper the title of 
which indicated only that it dealt with the occurrence of a beetle 
in Hawaii. If authors could train themselves to bear in mind 
the difficulties encountered by bibliographers and cataloguers, 
fewer such omissions would occur.
