two following) are so strong, that, in a group less subject to extra- 

 ordinary variation ttan this to whicli Alegoria belongs (JJlomides*), 

 they would necessitate the creation of two new genera. 



Alegobia quadraticollis, sp. n. 



Oblong, sub-parallel, depressed ; glossy black, the antenna;, tarsi, labruna and 

 maxillary palpi dark reddisli-brown, the labials bright red ; mentum strongly trans- 

 verse, broadly emarginate in front, nearly as broad at base as at apex, sides strongly 

 and sub-angularly rounded, coarsely (but not closely) punctured, sulcate down the 

 median line ; last joint of maxillary palpi elongate, ovoid, and truncate at tip ; 

 labrum broadly (almost arcuately) rounded in front, the anterior margin entire, 

 rather coarsely but sparingly punctured ; head •with a large transversely oval de- 

 pression on the front (but more posteriorly placed, and more nearly between the 

 eyes, than the similar depression in A. Sallei), with another, somewhat angular, on 

 the epistoma, at each side of its emargination ; antennary orbits much less pro- 

 minent in front of the eyes, and more oblique, than in A. dilatata, so that the 

 head, at the sides, is less parallel and angular ; epistoma more contracted in front, 

 and the emargination (or notch) naiTower and deeper than in A. dilatata or Sallei ; 

 epistomal suture obsolete ; sparingly and finely punctured ; the rest of the head — ■ 

 except the neck which is strongly rugose-punctate — moderately and not closely punc- 

 tured ; antennae with joint 2 large, sub-globular, 3 a little longer than 4, 5, or 6, and 

 all {i.e. 3 — 6) sub-cylindrical, 7 — 10 gi-adually broader, sub-triangular, moderately 

 perfoliate, 11 large, ovoidf ; prothorax sub-quadrate, depressed, wider than long, a little 

 narrowed anteriorly, slightly sinuously rounded at the sides, sinuously emarginate in 

 front, rather strongly sinuate at the base ; anterior angles somewhat prominent, 

 rounded ; hind angles obtuse ; sides and base margined (but not gi'ooved as in A. 

 Sallei), anteriorly the border is only faintly margined for one-third the width at 

 each side ; finely and not closely- — especially on the disc — punctured ; there are 

 three impressions at the base ; scutellum rather large and having three or four trans- 

 verse punctures on the disc ; elytra oblong, slightly widest behind the middle, 

 strongly depressed, sides somewhat sinuously and broadly margined ; base strongly 

 sinuous, humeral angle prominent ; rather finely punctate-striate, the pimctures 

 regidar and rounded ; intervals flat, sparingly and finely punctured, and slightly 

 (when viewed obliquely) transversely riigiUose ; legs shining black ; anterior femora 

 strongly compressed, sub-claviform, slightly more robust than the four posterior ; 

 the tibife are similar in form to those of A. dilatata, but less robust, and the denticu- 

 lations at the outer edge of the four anterior are inuch feebler and more regularly 

 formed in this species ; flanks of prothorax faintly longitudinally wrinkled ; meso- 



* In the genus Uloma. the palpi, mentum, &c., are well known to vary considerably in form, 

 &c., not only m the different species, but also in the sexes of the same species, and the character 

 offered by the epipleural fold, which may ordinarily be relied upon, is here inconstant, it being 

 (so far as my experience goes; more or less abruptly terminated before the apex of the elytra in all 

 the species h'om the Old World and froni North America, whUst in all those from Central and 1 

 South America it is more or less broadly continued to the apical extremity : the hind tarsi also 

 follow the same rule, all those species coming from Central and South America have the 1st joint 

 constantly shorter than the last, and all those from the Old World and from North America have j 

 the Ist joint constantly equal to— in some species longer than — the last. — F. B. 



tin A. dilatata the transverse joints are strongly perfoliate, and more or less obliquely! 

 truncated at each side the antennal axis, and the last joint is not ovoid ; in some examples the] 

 antenna; are slightly distorted, with joints 6, 7, or G, 7, 8 produced within, and somewhat pointed ; | 

 one sees a similar thing in 3 of Uluma orientali$, &c. — F. B.
