190 PEOF. P, B. UHLEB ON THE [Mar. 6, 



in having a white ring at the base of the apical joint of the 

 antennte, and in lacking the white cross on the inner margin of 

 the corium and clavus. There are two principal patterns of mark- 

 ing in this insect : one in which the upper surface is dusky black, 

 with the exception of the head, the anterior two-thirds of the 

 pronotum, and the base of scutellimi, which are red ; in the other 

 the insect is red above, excepting the base of the pronotum and the 

 membrane, which are black. In the female the underside is red 

 with a black edge to the basal margin of the ventral segments and 

 pleural sutures. In the male most of the venter is white, as are 

 also the collum and posterior border of the pleural pieces. The 

 rostrum of the male usually reaches to the middle of the second 

 ventral segment, but in the female it extends only to the basal 

 segment. 



Varieties occur which connect the two extremes of colour. The 

 legs vary in the amount of red upon the femora and tibiae. 

 Many of the specimens have these members piceous blackish. 



Length to tip of abdomen c? 8-10, $ 10-12 mm. ; width of 

 pronotum 2|— 4 mm. 



This species is also closely related to D. ruJicoUis, Linn., but it is 

 a much larger insect, with a longer head, exactly as iu D. suturellus, 

 H.-Schf., and with a proportionally longer rostrum in both 

 sexes. In D. rvjicollis all the specimens I have examined were 

 marked with a more or less distinct black dot behind the middle 

 of the corium. 



Many specimens were collected on both sides of the island. 

 At Balthazar they were found March 30, in considerable 

 numbers upon decaying oranges in shady places. On the Mount 

 Gray estate (leeward) they were taken, April 5 and 25, iu the 

 cocoa orchards, where they were brushed from the undergrowth. 

 In August and September they were found on the Mount Gay 

 estate and St. George's. 



The white colour of the base of the fourth joint of the antennae 

 is sometimes indistinct, but not quite absent.
