150 PAELATORIA ZIZYPHI. 



anterior laterals of from 6 7; and the posterior 

 laterals from 8 10. 



The lobes (PI. XXXII, fig. 5) are in four pairs ; of 

 these the first three pairs are well developed and sub- 

 equal ; but they are not so strongly trilobate as those 

 of the preceding species, and the basal portions are 

 decidedly more attenuated ; the fourth lobe is narrow 

 and pointed, and about half the length of the third 

 lobe, but compared with that of pergandii it is highly 

 developed. The arrangement of the spines is similar 

 to those of the last-named species ; but the anal and 

 vaginal openings are placed somewhat closer together. 



Puparium of the male (PL XXX, fig. 6) white, often 

 stained brown or yellow; very elongate, and departs 

 somewhat from other species in having the secretion 

 extended at the sides immediately behind the exuviae, 

 giving that portion of the puparium a bulged appear- 

 ance. Larval exuviae black ; the secretionary covering, 

 thin and white, is usually wanting in old examples. 



Long. 1 mm. 



Male. Legs hairy on the tarsi and anterior half of 

 the tibiae. 



Habitat. Common on imported oranges, but is 

 especially so on the Tangerine and Seville varieties. 

 They are most frequently met with on inferior fruit, 

 and I have counted as many as fifty examples to the 

 square inch. Not the least remarkable fact concern- 

 ing these insects is the ignorance which generally 

 exists concerning them. I have never met with a 

 fruiterer who ever recognised them as insects; but 

 find the general impression is that they are " seeds," 

 and they pass as such by the majority of those who 

 deal in them. I once asked a vendor how he ac- 

 counted for the presence of the fixed " seeds " upon 

 the orange rind. His reply was that he supposed they 

 became attached while the fruit was lying upon the 

 ground ! He could give no other explanation ! 



Distribution. Very abundant and destructive to 

 oranges in the Mediterranean area. Mr. Maskell re-
