8 ON THE GALL-MAKING COCCID^, BY H. L. SCHRADER. 



pointed at the apex, has shorter antennce, shorter anal setfe, and 

 not so mucli haii- fringing the abdomen. 



The male lai'va changes in the abode of the mother, into a 

 second form, Fig. v. ; in this it is red, active, and somewhat 

 longer than in its first metamorphosis, but narrow, and with 

 very short anal setae. After this it changes to a pupa (Fig. y.) 

 and then into the perfect male insect, (Fig. x.) which is also of 

 a crimson colour. 



The galls of Ascelis are generally of a large globose form, 

 and also in the shape of large flat swellings on both sides of the 

 leaves ; in either case I found the perfect males, together with 

 the larvae in different stages, in the month of June. But as I 

 have observed on the same trees galls of all sizes, both young and 

 full-grown, I hold it difficult to fix the time of their transforma- 

 tion. 



I observed also very minute specimens of Ascelis under the 

 tender bark of young shoots ; some were white, others black, 

 resembling little bags filled with ova. Owing to these attacks 

 the young twigs exhibited a very crippled appearance.
