64 THE SAX JOSE OR CHINESE SCALE. 
of young and old scale-insects, and frequently contains full-grown 
Pentilia larvae, their pupae, and freshly issued beetles. (See fig. 10.) 
This beetle was originally believed to be essentially an eastern species, 
and the fact that it attacked the San Jose scale so efficiently at the very 
outset was an interesting entomological experience, and led Doctor 
Howard to suggest its immediate introduction intj California, and one 
colony was sent, in 1894, to Professor ATood worth, at Berkeley. Our 
account of this useful beetle having come to the attention of Mr. J. E. 
Mclntyre, of Lespe, Cal., he urged us to procure for him some living 
specimens. Having already sent material to Mr. Woodworth. we were 
not immediately able to get a supply of the insects for a sending, but 
at this juncture we received from Mr. G. W. Harney, of Marysville, 
Cal.. some beetles for determination, which proved to be Microwt isea 
m isella. He reported that in the mountainous regions of Yuba County 
many apple trees had been very badly infested with A. periiiciosus, and 
that hundreds of these little ladybirds were found preying on the scale. 
The occurrence of this ladybird in California as thus determined, and 
the fact that it there had the same useful habit, was a most interesting 
discovery. TVe immediately had Mr. Mclntyre's request transferred 
to Mr. Harney for attention. It is more than likely that this little 
beetle is already widely distributed over the Pacific slope, and it may 
prove to have a continental distribution instead of being restricted to 
the East, as originally supposed. 
Another species of about the same size as Microiceisea misella, but 
dark wine-red in color and representing a distinct species, has been 
under observation for some time by Mr. Frederick Maskew in south- 
ern California, and at the time of the writer's visit to California in the 
autumn of 1903 his attention was called to this scymnid, and some 
material was collected and submitted to Mr. E. A. Schwarz, who pro- 
nounced it to be an unclescribed species. Mr. Maskew states that this 
little scymnid is always associated with the San Jose scale, and seems 
to be doing pretty good work against it. Mr. Schwarz has published 
a description of it under the name Pse'idoivcisra suturates. a 
A small predaceous beetle, Collops quadrimaculatus Fab., was 
observed by Mr. Schwarz at Charlottesville, Va., feeding on the larva 1 
of the San Jose scale. This beetle belongs to the family Malachiidae, 
concerning the life history and food habits of which very little is 
known. Evidently these beetles are in part at least predaceous, as 
evidenced by this observation by Mr. Schwarz. This beetle is, how- 
ever, not abundant enough apparently to have any practical value as 
i means of controlling the San Jose scale.
