on their inner narrow edge with stiff bristles) the outside one arising close by base of palpus, the 

 inside one extending lower down, and recalling by its form, the terminal joint of the front leg of 

 a scorpion ; maxillary palpi 4-jointed, joints cylindrical, short, very gradually longer and longer 

 from 1 to 4, the terminal joint more pointed and narrower than the others ; labium quadrangular, 

 labial palpi 2-jointed, the palpigerous piece strongly beset with bristles. Body, smooth with but a 

 few wrinkles at thorax ; polished translucent white, with faint bluish marblings on all but thoracic 

 joints which are slightly narrower than the rest ; a narrow vascular dorsal line, and a very slight 

 yellowish horny plate in a depression on joint 1 ; a very slight pubescence observable, and a trans- 

 Verse tergal row of sparse but tolerably long hairs on posterior part of each joint; more dense and 

 conspicuous hairs on lower sides of anal joint, which joint is short, cut off squarely, with a heart- 

 shaped swelling [Fig. 34, rf) sunk into a circular depression, each lobe of the heart with a darker 

 oval corneous elevation; spiracles sub-elliptical, dark chestnut-brown, placed on a prominent 

 swelling, the lateral openings all facing the head, the 1st on joint 1, the rest on joints 4, 5, 6, 7, 8, 

 9, 10 and 11, gradually becoming smaller and smaller from first to last. Legs (Fig. 34, / ) horny, 

 light-brown and covered sparsely with hairs ; coxse long and stout, with a rounded swelling at low 

 er anterior edge ; femora cylindrical, sometimes, distinctly, at others indistinctly, separated from 

 tibia 5 , sometimes prolonged into a thorn below, with a distinct carina along the inside, at others

Is there a grape-grower in 

 the State of Missouri who does 

 not know, to his sorrow, what 

 the Grape-vine Flea-beetle is ? 

 Hardly one ! And yet how few 

 ever connect it with its dis- 

 gusting little shiny brown lar- 

 vae, which generally prove still 

 more injurious thantne beetle, 

 by riddling the leaves in the 

 middle of the summer. 



The Grape-vine Flea-beetle 

 (Fig. 35, d )often goes by the 

 cognomon of "Steel-blue Bee* 

 Lie," and is even dubbed 

 •• Thrips" by some vineyaniists. 

 The latter term, however, is 

 The former name is not sufficiently charac- 



* The term Thrips is confined to an anomalous group of insects— mostly cannibal, but excep- 

 tionally vegetable feeding— of which Halliday made a separate Order (Thijsan, p!e>a), but which are 

 to-day'included in the llomoptera, or Whole-winged Bugs, by most authors, though they seem to 

 have close affinities to the Orlkoplera, and to the Pscudoneuroptera.
