2. A JAPANESE COCCID Ql'ARAN- 

 TINED AT SAN FRANCISCO. 



Leiicaspis japotiiciis, n. sp. — ? Scales 

 numerous on the twigs, pvriform, about the 

 form of Iilytilaspis pomoriim, but somewhat 

 smaller, whitish with a strong grevish- 

 ochreous tinge, exactly the color of the twig 

 on which they rest; exuviae strongly con- 

 trasting, dark chestnut color. The second 

 skin is large and narrow, only slightly over- 

 lapped by the first. 



5 Elongate, after boiling in soda pale 

 orange-yellow; four well-developed lobes, 

 similar in form, but the second smaller than 

 the first, all about as far apart as the breadth 

 of a median lobe, trilobed, the median lobule 

 largest, the others very distinct and some- 

 what spreading. The wide areas between the 

 median lobes, and between the first and 



second, aie each occupied by a pair of deeply 

 bifid plates, which do not extend to the level 

 of the ends of the lobes. The margin ceph- 

 alad of the second lobe is gently crenate, 

 the low broad elevations resulting, about 

 seven in number, being armed with three or 

 more minute spinules, really rudimentary 

 plates. Surface of hind portion conspic- 

 uously striate, anal orifice a long distance 

 from hind end, no groups of ventral glands, 

 but numerous large transversely elongate 

 scattered glands. The whole lateral margin 

 of the abdominal portion of the insect pre- 

 sents a thickened striate edge, with broad 

 serrate chalT-like scales at very frequent 

 inter\"als. 



Hab. -- On broom from Japan, found Dec, 

 1S96, by Mr. Alex. Craw in the course of his 

 horticultural quarantine work at San Fran- 

 cisco. 



Note. — Since the above was written. Prof. 

 Gillette has found the Lecaniiim flaveolnm 

 at the Colorado College. The proper name of 

 the plant, according to Mr. Cowen, is Piled 

 microphyllnm. — '^. D. A. C, March 2. 



THE LARVAL STAGES OF ARCTIA ANNA GROTE. 



BV HARRI.SO.N G. DVAR, NEW VOKK, X. V 



Eggs were obtained from a female moth of 

 the persephoiic form at Greenwood Lake, 

 N. J., in June. 



Egg. Neatly conoidal, the base flat and 

 concave; pale yellowish white, shining; 

 the reticulations very fine, broad, not sharp, 

 rounded, the areas between forming shallow 

 indistinctly margined pits; height, .6 mm., 

 diameter .9 mm. 



Stage I. Head bilobed, the lobes dark 

 blackish brown, clypeus pale, whitish ; width 

 .4 mm. Cervical shield narrow, dusky ; body 

 ■whitish, with long, stiff, dark setae; warts 

 pale; later both warts and leg-plates shining 

 dusky gray, large. Setae normal, the sub- 

 primaries absent, but wart iii on the abdo- 

 men bears two hairs, including the large 



subdorsal wart on joint 13 which has four 

 hairs. At the end of the stage the appear- 

 ance is whitish, the segments faintlv brown 

 dotted, not distincll\' banded, the warts dusky, 

 not contrasting. 



Stage //. Head bilobed, the lobes shining 

 blackish, clypeus pale; width .55 mm. Body 

 whitish, shaded with red-brown around the 

 dusky warts, giving the appearance of longi- 

 tudinal bands, especially a pale dorsal line. 

 Warts hairy, normal, large except i which is 

 very small and vi which is moderate. Hairs 

 stift", black, a few longer ones posteriorly 

 from the subdorsal wart on joint 13. After 

 eating, the body becomes sordid greenish, 

 the larva consequently appearing dark. 



Stage III. Head shining black, the cly-
