unknown. Mr. Hart's specimens are labelled as from Zamia but the 

 leaves seem to me to belong to some Amaryllidaceous plant. 



Destructiveness.— It occurs scattered on the leaves and is probably 

 not very injurious. 



(46.) Asterolecanium bambusce, Boisd. (The Bamboo Fringed-scale.) 



Diagnosis. — Larger than the other species, oval in outline, pale, green" 

 ish or greyish, with one end darkened by the body of the insect showing 

 through the scale. 



Distribution — Found at Moneague and Kingston, Jamaica. Messrs. 

 Urich and Limt have found it in Trinidad. It is found on cultivated 

 bamboo in Algeria, and Mr. E. E. Green has discovered it in Ceylon. 



Food-plants — Only on bamboos, on the stems of which it is often very 

 abundant. 



Destructiveness. — It must do some injury, but the bamboos are very 

 vigorous growers. 



(47.) Asterolecanium miliaria, Boisd. (The Flask-shaped Fringed-scale.) 



Diagnosis. — Smaller and narrower than the last, with the hind end 

 constricted like the neck of a flask. 



Distribution. — I did not find it in Jamaica, but Mr. Campbell detected 

 it at Castleton Gardens after I had left the Island. It appears to be 

 quite abundant in Trinidad. It was originally found on cultivated bam- 

 boos in Algeria, like the last. 



Food-plants. — Only on bamboos, on the stems and leaves. 



Destructiveness, — Doubtless injurious when abundant. It sometimes 

 covers the stems. 



(48.) Asterolecanium palmar, Ckll. (The Coco-nut Fringed-scale.) 



Diagnosis. — Very small and narrow, lemon-yellow. It is approximate- 

 ly boat-shaped in outline. 



Distribution. — Only known from near Montego Bay, Jamaica, where 

 it was found by Dr. Sinclair. 



Food-plants. — On leaves of coco-nut palm only. 



Destructiveness. — Does no appreciable harm. 



(49.) Asterolecanium urichi, Ckll. (Urich 's Fringed-scale.) 



Diagnosis. — Very small, elongate-oval, brownish, fringe reddish. Not 

 so narrow as pahnw, and not narrowed posteriorly like n liliai 'is. 



Distribution. — Only known from Port-of -Spain, Trinidad, where it was 

 discovered by Mr. Urich. 



Foou-plants. — On palms. 



Destructiveness. — Not complained of as injurious. 



Genus Orthezia ; the Lamella ted scales. 



These look something like mealy-bugs, but possess curious lamellar 

 formations of white secretion. Their ovisacs are white, and extend a 

 considerable distance behind the bodies of the females, which retain the 

 power of movement to the last. The males have a tuft of fine threads 

 at the end of the abdomen. 

 (50.) Orthezia insignis, Douglas. (The semi-nude Lamellated scale.) 

 Diagnosis. — The back is dark- colored (greenish to black), and has down 

 the middle two lines of white secretion, which diverge, leaving a space,
