THE COCCIDAE OV CALIFORNIA. 19 



4 and 5 shortest. There is an elongated protuberance each side of the 

 antennae. The legs are short and slender, with the tibia shorter than 

 the tarsus. The genito-anal ring has eight hairs. 



The full-grown male larva has 7-jointed antennae, joint 7 longest, the 

 rest equal. After impregnation the female becomes more round, fixes 

 herself, the secretion becomes much more abundant on the sides, making 

 at first lamellae, which afterwards unite into a cushion. The back 

 becomes smooth and the segmentation becomes plainly visible. The 

 dorsum is plane transversely, but curved longitudinally. Particularly 

 after the birth of the young, the female becomes well separated from 

 the waxy cushion, and is easily removed from it (even jarring will 

 accomplish the removal), leaving the noticeably empty white cup with 

 its fringed edges. 



Dr. L. 0. Howard gives the following description: 



Male. — " The antennae of the male are 10-jointed, the joints well 

 separated. The wings are represented by pads of varying length. The 

 poisers appear rather thick and fleshy, but lack the terminal hook. 



FIG. o. GDssyparia spuria. On elm. 



The abdomen is very stout, suboval, considerably broader than the 

 thorax, and when seen from above covers coxae, trochanters, and base 

 of the femora. Its segments are not well marked. A few days after 

 this form makes its appearance the cocoons begin to give out the per- 

 fect males, which issue with wings fully expanded. There seems to 

 have been a molt between this pseudimago and the perfect males, for 

 in no other way can we account for the difference in form. The 

 antennae possess the same number of joints (10), of about the same 

 relative proportion, although joints 3 and 4 are longer, but the incisures 

 are rather better marked. The poisers are lighter in color, and less 

 fleshy in appearance, and the curved hook is plainly visible at tip. 

 The abdomen is rather longer, much more slender, and tapers gradually 

 from base to tip. Its segments are well incised and plainly separable 

 from above. It does not cover the hind coxae and trochanters. The 

 tibiffi are longer in proportion to their tarsi. The anal segment gives 

 off two waxy filaments as long as the entire body. These filaments 

 were not noticeable in the pseudimago."
