PSYCHE. 



[February 1900. 



Stage VI. (abnormal interpolated) Head 

 1.85 mm. Coloration as in the next. 



Stage VI. (normal) Head whitish, black- 

 ish dotted, strongest in vertical suture, tu- 

 bercles black; width 2.2 mm. Body pale 

 yellowish green, approaching white, marked 

 essentially as in T. athasiaria and T.Jiscel- 

 laria and scarcely distinguishable from 

 them. A distinct subdorsal line of the 

 ground color; dorsal space faintly lined with 

 brown, irregular and crinkly; tubercles 

 dark. Sides, to below subventral fold, with 

 similar lines, but black and distinct, espe- 

 cially a geminate lateral one; subventral 

 fold pale; spiracles black. Venter pale with 

 a pair of faint lines. Feet and the cervical 

 shield orange tinted, except the anal feet. 



Food plant yellow pine. Larvae from 

 Brookhaven, Long Island, N. Y. Eggs June 

 17th, mature larvae in September, the win- 

 ter doubtless passed as pupa. Single brood- 

 ed. This larva differs from T. athasiaria in 

 food plant and manner of egg laying. The 

 larva assumes the mature coloration at 

 once in stage II, without any intervening 

 pattern. The specimens before me grew 

 very slowly and not vigorous, as shown by 

 its having eight stages instead of the normal. 

 It failed to pupate. 



THE FIFTH SPECIES OF KERMES 

 FROM MASSACHUSETTS. 



Kermes andrei «. $f. $ scale pyriform 

 in shape, very convex, 5 mm. high and 5 mm. 

 in diameter at its base, variable in some indi- 

 viduals which are nearly hemispherical. Sur- 

 face shiny. Color, light brown, with three 

 and sometimes four, very dark brown bands, 

 these variable in length and breadth. There 

 are also several suffused dark brown blotchy 

 spots and round dots, more numerous around 

 the posterior cleft. Segmentation obscure; 

 a median posterior keel-like prommence, 

 which is very much wrinkled above near the 



region of the posterior cleft. When boiled 

 in K. H. O. the dermis is colorless. Rostral 

 loop dark yellow, stout, not very long. No 

 antenna of legs observed. The larvae which 

 were formed in the body of the ?, are yel- 

 low, elongate oval, 360 micromillimeters 

 long, 160 broad. Antenna 6 segmented, 3 

 and 6 about equal and longest; i next, then 2 

 and 5 which are eqjuil ; 4 is the shortest. 

 Formula (36) i (25) 4 Antennal segments- 

 (1)20(2)16(3)24(4)12(5)16(6)24. Segments 

 4. 5 and 6 have a few short hairs. Legs 

 short and stout. Femur with trochanter 76 

 long. Tibia with tarsus 68 long. Tarsal 

 digitules long fine hairs with knobs: digi- 

 tules of claw reaching a little beyond the 

 claw. Caudal tubercles quite large, each 

 bearing one long stout bristle (120 long), 

 and three long stout spines (28 long). The 

 marginal spines point backwards and about 

 the same in length and breadth as those on 



Kermes andrei. 



tlie caudal tubercles. Rostral loop reaching 

 beyond last pair of legs. Eggs oval 320 long, 

 240 broad. 



Hab. — Lawrence, Mass., on white and red 

 oaks, Sept. 9, 1899. Associated with Kermes 

 galliformis, and found singly, not in clusters 

 as in the latter. They are not common and 

 tlie species seems to be viviparous. 



I am pleased to name this coccid in honor 

 of Mr. Ernest Andre of Gray, France, who 

 has shown me many favors in the study of 

 Formicidae. Tliis species appears to be very 

 distinct from all American Kermes. It looks 

 rather like the European K. gibhostis., but is 

 not the same. It is also different from the 

 other European species. A'. /<>////;' Eh rh. is 

 somewhat similar, but is evidently distinct, 

 being smaller, redder, with spots instead of 

 bands. Cockerell in litt. Nov. 18, 1S99.
