black spots (three per segment), besides the obhque black mark on sub- 

 ventral ridge and minute ventral dots anterior to the legs ; all bear short, 



stiff, black setai. 



***** 



Fifth ^z"^^,?.— Head clear light orange-red, shining, minutely sparsely 

 black pilose; eye on black spot; width, 1.4 mm. Abdominal feet on 

 joints 6-10 and 13, small with indications of feet also on joints 11 and 

 12; thoracic ones pale with slight black marks. Body as before; anal 

 plate black. 



Sixth stage. — Head well rounded, full at vertex, but narrowing to a 

 central apex ; sutures obsolete, but four dents in front indicate clypeus ; 

 shining light red with a few black setas ; eye black ; width, 1.8 mm. 

 Body cylindrical, of nearly even width to joint 13, which is a little smaller; 

 abdominal feet, corresponding spots on the apodal segments and anal 

 plate black ; no cervical shield : thoracic feet pale brownish. Segments 

 not annulate, • shining green, yellowish laterally ; nine large elevated 

 rounded black spots, .2 mm. in diameter, in a square on each side above 

 the stigmatal line on each segment, one below posteriorly to the spiracle, 

 and several small ones on the conspicuous, obliquely divided sub-ventral 

 ridge ; a small black patch at base of abdominal feet 7-10 and minute 

 ventral spots. Anal feet pale orange. A series of round medio-ventral 

 orange spots, almost between the feet on joints 7-12- 



SeventJi stage. — Width of head, 2.2 mm. (1.8 mm. in male?). Much 

 as before throughout, but the black spots are larger (.25 mm.), shining 



blue-black.*

Cocoon. — Double, open reticular, of yellow silk, the outer layer of 

 large meshes ; spun at the surface of the ground. 

 Lophyrus Lecontei, Fitch. 



Gregarious, eating down the needles of the pine. When disturbed, 

 the larvae raise the thoracic feet and eject a white fluid from their mouths. 



Head light red, eye and mouth black ; width : (^ , 1.8 mm.; ? , 2.2 

 mm. Thoracic feet rather small, black except at the joints. Abdominal 

 feet present on joints 6-12 and 13 (22 feet), all well-developed. Body 

 rather greenish-white, nearly opaque, slightly shining ; segments not very 

 distinctly 4-annulate, with rows of microscopic black spinules on the 



*The eighth stage was not noted. It probably escaped observation, as there should 

 be no increase in size of the head, and I neglected to isolate one larva.
