116. Gbomxtkid caterpillar 
This caterpillar, which occorred on the white pine at Brunswick, 
August 5, differs from a similar allied genus on the pitch pine in the 
body having a pair of tobercles on each abdominal segment,- and in be- 
ing generally more variegated. 
Liiri-i. — 1 dually increasing in width from the head to the anal legs, 
and much waned. Head small. not quite so wide as the prothoracic segment, which 
latter i> narrower than the metathoracic. Head -lightly bilobed, hemisphere well 
rounded. On each side <■: gment at: ending on each side in a 
small black tubercle. On the third ring from the end the tubercles are near together. 
Lateral line rongfa and with small warts. On top of metathorax is a tram 
I, General color, wood brown, slightly darker than the twig of 
the pine, but tuberculated like one. Mottled prettily with dark and light ti- 
lt is a genuine mimetic caterpillar. A dial . hinder part of each anal leg. 
Length, 40 mm . 
117. Geometrid caterpillar. 
Larva. — Head bilobed, each lobe rounded, front tlar. with abroad transverse whit- 
ish band, including the clypeus. and tinged on the edge with reddish below ; above 
ind the front is dark. Body rather slender, smooth, not wrinkled : a large lat- 
b, rounded tubercle, low down on the side of second abdominal segment : 
the tubercle is dark browu, smooth, and white in front. Eighth abdominal segment 
slightly humped dorsally. A pair of white dorsal dots on front edge of each abdom- 
inal segment : obsolete, however, on posterior part of body. Four dark piliferous 
dots <>n tip of each abdominal segment, the two in front more remote from tl 
terior pair than usual. Spiracles forming a black ring. In appearance and color it 
monies a smooth light brown piue twig. Length. 25*". 
11?. Phycid caterpiilak. 
Order Lepidoptera : family Phycid.e. 
This caterpillar forms at the base of the terminal leaves of the pitch- 
pine, in Maine and Rhode Island, through September into October, a 
large mass of castings, sometimes 3 inches long, enveloped in a thin 
light web. October 20 one was observed making a loose, thin, slight 
web over the end of a branch, leaving its nest and crawling over it. 
The larva also resides in a long, slender, twisted tube made of its cast- 
ings lined with silk. Several attempts to carry the larva- through the 
winter proved unsuccessful. 
Larva.— The body rather thick, a little flattened, not tapering rapidly towards the 
end. The head large, but not quiie so wide as the prothorax. in which it can r 
pale chestnut-brown, with jet black patches behind and on the sides: two 
elongate black marks on the middle of the vertex. Cervical shield concolorous. with 
the head broad and oieecent-ehaped. Each abdominal segment is divided trans\ 
behind the spiracle by a deep impressed line, while each portion of the segment thus 
divided is finely wrinkled. 
The ground color is a pale chestnut with a broad dark subdorsal longitudinal 
baud which extends down the sides to just above the spiracles. The terminal tenth 
segment is clear pale chestnut. Under side of the body and feet pale chestnut with 
scattered black dots. No dorsal tubercles, although the hairs are present. Length. 
i: mm .
