ALTICA TORQUATA LE CONTE, THE BLUEBERRY 

 FLEA-BEETLE. 



Technical Description of the Stages, 

 description of the adult. 



Elongate oval, convex ; body above brilliant cupreous with metallic 

 reflections; antennae cupreous, becoming more or less piceous distally; 

 segments 1-3 nearly smooth, the others (especially the distal ones) quite 

 densely pubescent with fine whitish setae : slightly less than one-half 

 the length of the body, and considerably less than twice the width of 

 the prothorax at its base ; segments 2-3-4 successively longer : segment 

 4 about two and one-half times as wide as long: segment 10 not more 

 than twice as long as wide, frequently less ; eyes black, their width as 

 seen from the front less than one-half the interocular distance ; frontal 

 carina moderately prominent, acute ; frontal tubercles moderately large, 

 almost contiguous ; vertex not punctate ; width of head across eyes a 

 little more than two-thirds that of the prothorax at its widest point. 



Prothorax about two-thirds wider than long; margin narrow, 

 thickened at the basal and apical angles ; base but little wider than the 

 apex, regularly arcuate caudad ; sides nearly parallel at the base, con- 

 vergent at the apex; basal angles subacute, prominent; apical angles 

 rounded ; surface alutaceous, comparatively finely and closely punctate ; 

 ante-basal groove shallow and incomplete. 



Elytra (across umbones) one-fourth wider than the base of the pro- 

 thorax ; each elytron three times as long as wide, and slightly more than 

 twice as long as the width of the base of the prothorax ; surface minutely 

 alutaceous, comparatively coarsely but densely punctate; humeral angle; 

 rounded ; umbo scarcely prominent ; post-humeral depression slight. 



Scutellum colored like the elytra, sparsely punctate. 



Body beneath colored like the body above, with strong greenish 

 reflections ; abdomen quite densely beset with fine white setae. 



Legs colored like the body; claws red brown, pulvilli light brown; 

 setae white ; the femora of the hind legs are especially large, even for 

 an Altica. 



Last ventral segment of male sinuate each side; lateral lobes small, 

 median lobe short, semicircular, flat, with a sharply defined impressed 

 median line running about half the length of the segment. 



Length, 5 mm. 



Figure 12H is reproduced from the photograph of a beetle of this 

 species. The last ventral segment of the male is shown in figure 11F.
