236 HETEROMERA. 
Eight examples. In the male of this species the antenne are distinctly longer, and 
the apical joint more elongate, than in the female; the tibis are slender and unarmed 
in the male, and similar in both sexes. 
6. Anedus marginatus. (Tab. X. fig. 18.) 
Elongate ovate, brownish-piceous, shining, clothed with a few widely scattered erect hairs. Head with a few 
scattered coarse impressions, transversely impressed in front; antennee very long, stout, ferruginous, 
joint 2 very short and strongly transverse, joint 3 short, longer than 2, and rather broader than long, 
joint 4 more than twice as long as 3, joints 4-10 long and very slightly lengthening outwardly, joint 11 
much longer than 10, slightly widening outwardly, and with the apex obliquely subtruncate; prothorax 
strongly transverse, the sides subangularly extended about the middle, thence rapidly and obliquely 
narrowing and sinuous to the base, rounded and scarcely narrowing anteriorly, the lateral margins slightly 
extended and prominent, the anterior angles broadly rounded, the posterior angles distinct but not acute, 
the surface very irregularly, coarsely, and rather distantly punctured ; scutellum smooth; elytra rather 
long, strongly margined, coarsely and closely punctate-striate, the interstices smooth and feebly convex, 
piceous, the sides and base broadly and indefinably sordid testaceous, the shoulders still paler; legs long 
and slender, testaceous. . 
Length 4 millim. (¢.) 
Hab. Panama, David in Chiriqui (Champion). 
One example. This small species will be known amongst its allies by its long legs 
and antenne, anteriorly widened thorax, and seriate-punctate elytra, the margins of 
the latter sordid testaceous. Of the Central-American species it is nearest allied to 
A. longicornis. 
7. Anedus apicicornis. (Tab. X. fig. 19.) 
Oblong ovate, brownish-piceous, slightly shining, the upper surface rather thickly clothed with long, suberect 
hair. Head coarsely and subconfluently punctured, broadly and transversely impressed in front, the 
anterior part red; antenne long, stout, thickly clothed with short hair, joints 2 and 3 very short, strongly 
transverse, subequal, and together not nearly equalling the fourth joint in length, joint 4 more than three 
times as long as 3, joints 4-10 very slightly widening outwardly and almost equal in length, jomt 11 
longer than 10 and bluntly rounded at the apex, the three basal joints and the apical one red, the rest 
piceous ; prothorax strongly transverse, the sides strongly and obliquely narrowing before and behind the 
middle, rather more narrowed posteriorly, and constricted just before the base, the lateral margins slightly 
extended and prominent, the apex broadly but not deeply arcuate emarginate, the hind angles narrow and 
acute, the surface very coarsely and closely punctured ; scutellum coarsely punctured; elytra rather long, 
coarsely and closely punctured (not quite so closely or coarsely as the prothorax), the punctures here and 
there transversely confluent and submuricate, the sides and base (the shoulders more prominently) inde- 
finably reddish, the disc piceous; legs and oral organs reddish-testaceous. 
Length 33 millim. 
Hab. Panama, David in Chiriqui (Champion). 
One example. <A very distinct little species. 
8. Anedus brevicollis. (Tab. X. fig. 20, 3.) 
Oblong ovate, broad, brownish-piceous, shining, clothed with a few scattered suberect hairs. Head exceedingly 
coarsely, irregularly, and distantly punctured, transversely impressed in front, the anterior half red; 
antennee stout, comparatively short, joint 2 very short and transverse, joint 3 rather more than twice as 
long as 2, joint 4 slightly longer than 3, joint 5 shorter than 4, joints 5-10 widening outwardly and equal
