[An elongated slightly curved scale insect, infesting citrus 

 trees.] 



This species of scale insect has not been found on any of 

 the citrus trees in this State, so far as I know, but it will be 

 strange if it is not found in the near future. It is not a rare 

 occurence to find it on oranges, etc., which are imported from 

 Europe, Australia and Tahiti, and offered for sale on fruit 

 stands throughout the State. 



Tlie scale of this species (Fig. 137, J((, i/>)is similar in form 

 and appearance to that of the oyster shell bark-louse {M. 

 pomorunij Chap. XIX), excepting that it may be a little wider 

 at the posterior end. Length of female scale about one and 

 one half lines. The male scale (Fig. 137, Ic) is similar to 

 other species of MytiUispis in having a hinge-like joint, poste- 

 rior to the middle of the scale, so that b}' lifting the posterior 

 part up, the perfect insect (Fig. 138a) can emerge.
