: REPORT OF THE STATISTICIAN. 257 
to attain full growth I have not been able to ascertain, but, in all proba- 
bility, it remains at least one month, and probably several more, in the 
ground, where the pupa state (Pl. VI, Fig. 2, b) is finally assumed. 
As the injury of this insect has been done mostly to roses under glass, 
there will be found no great regularity in its periods of. transformation 
under such circumstances. In point of fact it is found in all stages 
during the winter and early spring months. 
In addition to the recommendation of Mr. Henderson to destroy the 
perfect beetles, I would recommend, therefore, as an effectual preventive 
measure the tying of a few thicknesses of tape or of narrow pieces of rag, 
or even of stiff paper, around the butt of the plant to be examined, de- 
tached every three weeks, and burned if eggs are found in them. Where 
the number of plants is large, this destruction of the eggs might be expe- 
dited by the employmeut cf traps consisting of small stakes around 
which such layers of cloth or paper are tied. These should be thrust in 
the ground near the main stem of the plant and can be collected once 
every three weeks, thrown into a tub of hot water, subsequently dried, 
and used again without untying the bandages. A few folds of oil-paper 
thrust into a slit in an ordinary wooden label—materials always at hand 
in a green house—mnight also be advantageously employed. 
DESCRIPTIVE. 
ARAMIGUS FULLERI.—Egg—0.9™™ long and about one-fourth as wide; smooth, soft, and pale translu- 
cent yellow; normal form ellipsoidal, but varying greatly from being compressed in the rows. 
Larva—Length, 8™; color, milky white; apodous; normally arched above, flattened below; trans- 
versely wrinkled, there being about three wrinkles dorsally to each joint; also deeply and broadly im- 
pressed laterally, the impression being more conspicuous by the folds, each side of it appearing as glob- 
ular tubercles; sparsely covered with yellowish, setous hairs; head, honey yellow, retractile, nutant, 
flattened below ; mandibles long, strong, darlx brown, almost black, 2-toothed; maxillz with a fringe of 
long hairs at the end; palpi short, conical, 3-jointed, the terminal joint longest; antenna rudimentary, 
represented only by a small tubercle ; labium rounded basally, truncate at the tip ; labial palpi 2-jointed; 
a cervical shield, which is highly polished and chitinous, and has a dusky mark near the anterior border 
and a few dusky spots behind, covers the dorsal portion of the pro- and meso-thoracic joints; stigmata 
normally placed, all but the first pair being very small, almost imperceptible; largest at the first ab- 
dominal joint, tapering very gradually thence to anus; ventrally the setous hairs are shorter but stiffer, 
those on the thoracic joints being especially stout where the legs would otherwise be. 
Pupa—Length, 7; color, milky white; head, rostrum, and thoracic joints with a few short, stout 
bristles; flagellum of the antenna bent at right angles to the scape; wing-sheaths reaching to sixth 
abdominal joint; anal joint with two short, strong, slightly incurved spines, arising from a fleshy prom- 
inence on each outer side, giving to the tip of the body a square aspect; one or more short, stout bris- 
tles an the end of each femur, and a transverse row of more minute dorsal hooks on each abdominal 
joint. 
REPORT OF STATISTICIAN. 
Sir: My report as statistician of the Department of Agriculture is 
respectfully submitted. 
The system of collecting information and compiling returns used by 
my predecessors, and which is continued in this report, seems to be the 
best and only method available for a country embracing an extent of 
area anc variety of climate so great as ours. 
The importance of statistical information of agriculture is conceded 
by all who have given thought to the subject, and has attracted the 
attention of scholars since the remotest ages; still the difficulty of find- 
ing persons who are capable and willing to furnish reliable estimates, 
the limited amount of appropriation, the lapse of years from one census 
to another, and the apathy of so many of the States in regard to their 
own statistics, all tend to make the most careful estimates at times inac- 
curate. i 
In fact, the national census never agrees with the State returns. Dis- 
crepancies and differences always appear.
