(i ( J4 FIFTH REPORT OF THE ENTOMOLOGICAL COMMI88ION. 
Ion sinus posteriorly, and with the side* projeoted Inwards; it consists of two series 
of callous spots, the outer forming ths limits of the area as above described, and the 
inner Beriea forming ■ simple transverse, narrow, lanceolate, oval spot. The callous 
spot on the under side has a sinus in front, hut slightly rounded behind. The oue 
on the seventh segmenl (in-low) is bnt Little more than one-half as wide, with a 
broad sinus on the hind edge, and with the sides directed obliquely inwards. Ter- 
minal segment rery small, half as wide, and one-fourth as long as penultimate 
segment. Nine spiracles, the first on front edge of second thoracic (mesothoracic) 
segment. Length when fully grown, H inches. 
This larva may be known from that of Bhagimm Hiieatum by its lack of any thoracic 
leet and by its nnich Longer, more cylindrical body, and differs at once by the 
Long, square bead, thai <>t Rhagiwm rounding in front; by the wider clypeus, and 
proportionately wider and shorter labium. The palpi and antenna- do not differ 
mm h. The callous spots on the abdominal segments are smaller and otherwise 
different from those in Bhagium. 
Pupa. — The pupa is far advanced, being nearly ready to change to a beetle, the 
body becoming dusky and horn-colored, while the characteristic dark spots have al- 
ready appeared on the w r ing-covers. The antennae are coiled up three and a half 
times at the end between the fore and the middle pairs of legs, and the genus may 
be recognized by their great length and the deep excavation in the head between 
them, as well as by the lateral short spine on the prothorax. 
The wing-covers in my single specimen reach to the third abdominal segment, and 
are pressed obliquely to the side of the body. The salient portions of the upper side 
of the abdominal rings are provided with fine spines. End of the body sinuate. 
In the absence of another pupa of this genus for comparison, additional character- 
istics can not now be given. Length, three-fourths of an inch. 
Mr. George Hunt has taken both this species and M. scutellatus 
"coming out of the white pine" in July in northern New York and in 
Rhode Island. Prof. F. H. Snow records it in the seventh volume of 
the Transactions of the Kansas Academy of Science as occurring in 
the Baptist church in Lawrence, Kaus., " where repairs had been made 
with pine lumber." 
Although I have seen no specimens of the larva or of the beetle from 
the Southern States, I have no doubt but that it is the larva of this 
species which from North Carolina southwards is called the " sawyer." 
Mr. Thomas C. Harris, of Raleigh, N. C, has informed me that a larva 
of this description has killed mauy pines in that State. In June, 1884, 
he sent me the following extract from a local paper, which bears on 
this subject : 
We were informed by Maj. C. W. McClammy, of Scott's Hill, Pender County, that 
the pine trees are dying in his own and other sections of Pender and New Hanover 
Counties. It is supposed that it is the *' bore-worm" or "sawyers," which played 
such havoc with the pines something over thirty years ago, that are operating upon 
them now. Their ravages are not confined to the old trees, the young ones dying 
just as rapidly and numerously. 
The following extract from the Scientific American refers to what is 
with little doubt the species we are now considering : 
A correspondent of the Northwestern Lumberman says : It is not generally known, 
yet a fact, that extensive and valuable forests of yellow pine in the Southern States 
are destroyed by a worm, commonly called here at the South a "sawyer," or fiat
