March, 1920.] NOTMAX : COLEOPTERA COLLECTED AT SciIOIIARIE. 31 



sparsely punctate. Pubescence short, sparse and pale. ScutcUum elongate, 

 obtuse at apex, closely and finely punctate. First joint of the posterior tarsi 

 a little longer than the second. Length, 13.5 mm.; width, 3.5 mm. (i.) 



This species is closely allied to L. fulvipes Bland. In addition 

 to the differences in color, it may be distinguished by the more elon- 

 gate and parallel-sided thorax with the anterior angles rounded and 

 narrowly depressed and the more strongly divaricate posterior angles 

 and by the elytra distinctly wider. 



In the latest classification of the Elaterid.-e by Schwarz in Genera 

 Insectorum, Ludiiis Esch. is used in place of Corymhitcs, Limonius, 

 etc., a change justified by the fact that Corymhitcs Latr. was defined 

 to include only the species with semi-pectinate antcnncC in the male, 

 and that Ludius Esch., an older genus, is defined to include species 

 with unmargined front, simple claws, unlobed tarsi and narrow coxal 

 plates. 



Lixus crassulus new species. 



Form elongate, cylindrical, moderately slender. Color black, shining, 

 antennas and tarsi picescent. Pubescence short, scale-like, yellowish, more dense 

 on the sides. Head and beak finely and rather densely punctate, a deep rounded 

 fovea between the eyes and a short stria between the antennae; beak cylin- 

 drical, as long as the head and thorax, strongly arcuate; antennae inserted at 

 apical two fifths, scape not as long as the remaining joints ; first two joints of 

 the funical, elongate, subequal, second as long as the following two. Thorax 

 one third wider than long; sides rather strongly arcuate and convergent from 

 base to a little more than apical one fourth where they are rather strongly 

 constricted; apex one half the width of the base; disk impressed, impression 

 wider and deeper at the base; finely and densely punctured; sides of the im- 

 pression coarsely rugose-punctate at base, a few coarse punctures on the apical 

 half. Elytra slightly wider than the thorax and three and one half times as 

 long; sides parallel to apical third and thence obliquely rounded to the con- 

 jointly rounded apex ; a rather deep scutellar impression ; surface very finely 

 and indistinctly punctulate with rows of coarse, well separated punctures, 

 becoming smaller apically. Length, 13.5 mm.; width, 4.5 mm. i $. 



This species is distinguished from L. concavus Say by its slightly 

 broader form, wider thorax with sides more strongly rounded and 

 constricted and the much less numerous coarse punctures on the 

 apical half of the disk.
