2i8 MEMOIRS ON THE COLEOPTERA 



conspicuous;' prothorax fully one 1 half wider than long, strongly 

 rounded at the sides anteriorly, the sides gradually oblique and 

 straight posteriorly to the obtuse angles, which are sharply denned and 

 often minutely prominent; apex broadly and moderately sinuate and 

 subequal to the very feebly arcuate base, which is finely and strongly, 

 evenly beaded; surface moderately convex, smooth, with vestiges 

 of minute sparse punctulation throughout, rather broadly reflexed 

 and rugosely punctate at the sides, the gutter even in width from 

 apex to basal third where it disappears in the large concavo-ex- 

 planate latero-basal parts, which merge gradually into the large and 

 rather deep, rounded and coarsely, densely punctured fovese; the 

 median parts of the base are also depressed and distinctly punctured; 

 anterior impression distinct, rather closer to the apex than in 

 Anisotarsus; stria distinct and subentire; elytra oblong, parallel, 

 with feebly arcuate sides, rather more than one-half longer than wide 

 and a third wider than the prothorax, obtuse at apex, the sinus long 

 and distinct; striae strong and impressed, the scutellar very long; 

 intervals rather strongly convex throughout, the discal puncture 

 coarse and at three-fifths; suffused punctures dense near the sides, 

 where they bear minute hairs. Length (cf 1 9 ) 12.8-13.5 mm.; 

 width 4.8-5.0 mm. North Carolina (Asheville), Iowa and Kansas. 



verticalis Lee. 



The genus Spongopus was considered as scarcely distinct from 

 Anisotarsus by Lacordaire, but it has an altogether different 

 habitus, as may be inferred from the description, and is without 

 much doubt a distinct genus. 



The Central American Notiobia leiroides and parilis of Bates, 

 of which I have specimens from Honduras, almost exactly resemble 

 Spongopus verticalis in outline, facies and in the dense integuments, 

 but the eyes are larger and more conspicuous; the transverse cordi- 

 form prothorax is similar in the sharply marked hind angles, but 

 is without lateral or basal punctuation; the elytra are devoid of 

 all trace of diffused punctuation and the paraglossse are entirely 

 different in form, being broadly truncate at apex and not in the 

 least prolonged at the external apical angle. The mentum tooth 

 is well developed, much as in Spongopus. In a natural arrangement 

 Notiobia Perty, would therefore come between Anisotarsus and 

 Spongopus. The elytral striae in parilis are sulciform and are 

 especially deep along the summit of the lateral declivity. 



Tribe ACUPALPINI. 



The chief distinguishing characters of this tribe are the bisetose 

 second labio-palpal joint and the form of the frontal fovese; it
