belonging to this group discovered in this country, all other known species belong- 

 ing to the Australian fauna. The galls are situated on the lowei side of the h-af, 

 with a nearly closed slit on the upper side. The mouth of the slit, which is parallel 

 with the midrib, is beset with a pale grayish pubescence. The gall itself is quite 

 large, somewhat conical, laterally compressed, leaning over to one side, and ending 

 in a slightly curved point, the whole resembling a broad, flat tooth. They are green 

 on one side and crimson or purplish on the other, and closely covered by a short 

 grayish pubesence which can easily be rubbed off. Each of these galls contains at 

 this date a single specimen, which rests in the lower or pointed end of the gall. They 

 have cast at least one skin and some evidently two. The insect is orange, broad 

 oval, somewhat more pointed posteriorly, and with a fringe of short stiff hairs 

 around the whole margin. The antennaj are six-jointed, the third being the longest. 

 Eyes small and brown ; pro- 

 boscis stout, reaching be- 

 tween middle coxa*; legs 

 stout and rather short. 



Received June 12, 1882, 

 another lot of these galls, 

 which are now almost 

 woody and quite hard. 

 Most of them contain the 

 insect, although others are 

 empty, and some are in- 

 habited by a lepidopterous 

 larva, which preys upon 

 the coccid. This coccid is 

 a most remarkable insect. 

 Its upper or dorsal surface 

 is quite flat and fits closely 

 to the walls of the gall, 

 and around the whole mar- 

 gin is a narrow elevated 

 ridge. The color of the 

 dorsum is dark purplish 

 brown and is slightly cov- 

 ered with a delicate prui- 

 nose substance. The lower 

 or ventral side Alls entirely the lower end of the gall. It is orange and also somewhat 

 covered with a mealy excretion. The legs are free and movable, tf o eggs or larva 

 were found. The lepidopteron is purplish, the head brick red, cervical shield some- 

 what paler anteriorly, with a broad black posterior margin. The body is marked 

 each side with a somewhat irregular row of minute whitish spots and similar spots 

 across the middle of the segments. The venter is pale dirty grayish yellow. Length 

 of the largest about 7 mm. 



Received May 25, 1883, some of these galls on Q, emoryi from Mr. Morrison, Port 

 lluachuca, Ariz. 



DAMAGE BY THE WHITE PINE BUTTERFLY.

At the meeting of tbe Entomological Society of Washington, held 

 March 18, 1890, Dr. James Fletcher, the Dominion entomologist of 

 Canada, referred to an outbreak of the white pine butterfly (Neopkasia 

 menapia) in the elevated arid plateau which forms the interior of British 

 Columbia. The larva 4 of this insect, according to l>r. Fletcher, in this 

 locality feed entirely upon the leaves of the yellow or bull pine (Pimm 

 ponderosa), while at Vancouver Island, where this pine does nor occur.
