PSYCHE. 



[June 1900. 



iib all separate, no subpriniaries. A small 

 trapezoidal cervical shield and ronnded anal 

 plate. 



Stage II. Head broad, the lobes produced 

 with short points directed forward; sutures 

 impressed; dull, dark black-brown, a little 

 mottled; secondary hairs present, short, 

 black; width .5 mm. Body slender, the cen- 

 ters of the segments a little swollen; all dark 

 blackish vinous with an olivaceous tint, under 

 the lens obscurely finely lined longitudinally 

 with darker ventrally. In the position of 

 tubercle iv an elevated rounded dark spot. 

 Segments centrally dorsally shaded with 

 dark. Skin covered witli fine, short, dark, 

 secondary hair arising from black tubercles. 

 Venter of joint 10 protruded, the segments 

 finely annulate, all essentially as in the ma- 

 ture larva, though darker. 



Stage III. With the characters of the ma- 

 ture larva. Head .7 mm. The black rounded 

 stigmatal lumps and the paired posterior dor- 

 sal ones present on joints 8 and 9, the latter 

 one smaller. Dark, blackish brown, a little 

 lighter and greenish ventrally, peppered by 

 the dark secondary tubercles. The fine sec- 

 ondary setae black. Head points distinct. 

 The ends, joints 2 to 4 and lo to 13, are nearly 

 black. No marks nor lines. 



Stage IV. Head bilobed, the lobes pro- 

 duced into cones with sharp tips curved for- 

 ward, not long but pointing obliquely forward 

 and outward; clypeus as high as two thirds 

 of the front; cheeks rounded, quadrate below, 



mouth projecting. Blackish, dotted with 

 pale, an irregular white fleck on the face of 

 the lobe below the horn ; densely covered 

 with sliort, black, secondary pile ; width 1.4 

 mm. Body as in the next stage, the coloi" 

 darker, less green, the prominences a little 

 less pronounced. 



Stage v. Head bilobed, the former points 

 represented by slight elevations on the upper 

 front side; color as before; width 2.1 mm. 

 Body nearly cylindrical, the subventral fold 

 distinct and arched on the segments; a pair 

 of short, erect, black lumps on joints S and 9 

 in the position of tubercle ii, those of joint 8 

 the larger; a slight elevated black spot in the 

 position of tubercle iv on joints 5 to 9; venter 

 of joint 10 protruded. Body all densely cov- 

 ered with fine, black, secondary pile from 

 small black tubercles, almost spiny on the 

 dorsal elevations. Dull olivaceous green, the 

 green predominating with growth, though 

 some examples remain vinous to the last, 

 shaded with brown, especially in the centers 

 of the segments dorsally and on the posterior 

 rims, darkest on the contracted end parts; a 

 series of fine medio-ventral dashes ; segments 

 very obscurely 8-annulate; spiracles white, 

 black rimmed; feet brown. 



The larva pupates in the sand, spinning a 

 very slight cocoon of silk. The slender light 

 brown pupa has long projecting leg cases. 



Food plant, Coccoloba floyidaua., only the 

 young leaves being eaten. Larvae from Palm 

 Beach, Florida. 



SOME COCCIDAE QUARANTINED AT SAN FRANCISCO. 



BV T. D. A. COCKERELL, N. M. AGR. EXP. STA . 



Mr. A. Craw has recently sent me a fresh 

 lot of Coccidae, which he detected on plants 

 about to be landed at San Francisco; and it 

 is interesting to note that, even after so 

 many years of horticultural quarantine, new 

 species are met with. Thus we can never 

 know what new pest may arrive at our ports. 



the absence of an insect in the past proving 

 nothing in regard to the future. --
