256 THE CANADIAN ENTOMOLOGIST. 



It is very close to the California confinis, but may be distinguished by the 

 punctuation being generally finer. It may be a race of vicinus without 

 banded elytra and smaller than the type. 



RhyncopJiorce — Artipus floridaiius, popularly known as the " rose 

 bug," does not seem to hibernate at this season, if indeed it ever does ; 

 it exists in great numbers and does as much mischief as its northern name- 

 sake ; though polyphagous, it seems to have a special fondness for citrus, 

 particularly the lime, destroying the blossoms and young fruit, and like- 

 wise nipping the margins of the leaves, which become white, giving the 

 tree a stunted, frosted appearance. On the main land this beetle feeds 

 on the leaves of the live oak, and of such, many are of a brilliant verdigris- 

 green colour, instead of the creamy white of those raised on citrus- 

 Macrops cryptops and Listronotu^ setosus are foundabundantlyin the flowers 

 of Sagittaria. Notolomus basalis abound from the middle of February 

 till the various Palms are out of bloom. Cryptorhyiichus lutosus breeds 

 abundantly in the disks (rods) of an abnormal leguminous shrub, 

 Ecastophyllum brownei. The most of the fruit ripens and falls from the 

 bush before February, at which time the beetles escape, but the few 

 belated disks found ripening, in nearly every instance contained a beetle 

 in some stage. The determination of both beetle and plant is due to 

 Mr. Schwarz, who had previously taken this insect at Biscayne Bay. 



Mesites rufipennis — One example, $ , was taken on the beach ; the 

 antennse are inserted about the middle of the beak, which is coarsely 

 punctured to the tip, and has the usual frontal fovea and deep groove 

 extending in front of the insertion of the antennae ; on its under side is a 

 deep broad groove extending from the tip to the gula. This species 

 resembles closely immature examples of M. subcylindricus, but is more 

 depressed, and the elytral intervals are less convex and more finely 

 punctulate. 



ScolytidcE — The examination of dead hardwood indicated that several 

 species of this family were abundant in their season. The larvae of one 

 small species was observed in almost incredible numbers boring outwards 

 in the bark of Ficus aurea, preparatory to pupation ; they were so close 

 together that the surface of the back could scarcely be seen. They were 

 white, about .06 inch long, and too numerous to make traceable galleries 

 under the bark, not being wood borers.
