ESSIG, NOTES ON CALIFORNIA COCCIDAE 



93 



The body proper (Figs. 39, B, C) is jet black and the size of a small 

 garden pea. Its chief characteristic is a long anal projection nearly half as 

 long as the body. This projection or tail corresponds to the anal plate in most 

 coccids, and is two lobed (Fig. 39 D). 



The male has never been obtained.

Figure 39. Ceroplastes ceriferus 



This most interesting form was taken at Mexico City and Guadalajara, 

 Mexico, by David Crawford. It occurs in great numbers, infesting Hibiscus 

 in the public gardens of the cities. Nothing is being done to stay its ravages, 

 which are very severe. 



Chionaspis quercus Comst. 



Femalb. Scale — (Fig. 40 and 41 B). — The scale is long and tapers from 

 the anterior to the posterior end. Length, 1 mm. to 2 mm. ; width, J/^ mm. to 

 1 mm. The color is gray and very hard to distinguish from the oak bark. 



Body — (Fig. 41 A) — Greatly resembles Lepidosaphes beckii in shape and 

 manner of segmentation, being much broader at the posterior end and the 

 sides deeply segmented. Pygidium (Fig. 41 E) consists in one large median 

 lobe, instead of the usual two with two smaller lobes and a rudimentary lobe 

 on both sides. The spine arrangement is as follows : median lobe — 1 large 

 and 2 small, second pair lobes — 1 large and 1 small, third pair — 1 on tip and I 

 on middle. Spinnerets — consist in 4 — 6 marginal, 18 — 22 lower laterals, and 

 18 — 20 upper laterals. 



Male. Scale — (Fig. 42 B) — Is white with three ridges extending from 

 the anterior to the posterior end. Length, J^ mm. to 1 mm. ; width, J/g mm. to
