COCCIDAE FROM LOWER CALIFORNIA 



123 



neither elongate nor annulate; pygidium (Fig. 43B) with a single pair 

 of widely separated lobes. 



Notes: While this species is in most respects quite typical of the genus 

 Odonaspis the presence of the invaginated apical tube is a peculiarity which it 

 shares with but one other species, O. canaliculata Green. The latter species has 

 been recorded only from India but in spite of the great geographical separation 

 the two are certainly very closely related, differing chiefly in the fact that in the 

 Indian species the circumgenital pores are lacking and the apical invagination 

 extends nearly to the anal opening.
