globose, fourth fusiform, moderately acuminate ; antennae short, 

 thick, intermediate and penultimate joints transverse ; prothorax 

 subcordate and with three foveae, transverse sulci connected with 

 one another, base with several punctures ; elytra moderately elongate, 

 subparallel, dorsal stria short ; first four abdominal ventral segments 

 subequal, both sexes with six ventral segments, the first one with a 

 triangular depression between the coxae, the second to the fifth 

 gradually decreasing ; presternum carinate, posterior coxae near one 

 another. 



The facies is that of Euplectus, but the presternum is carinate. 

 Its nearest ally is the North American genus EiUyphlus.

 Plate XVI., fig. 17. 



Pale ferruginous, and with a brief, pallid pubescence ; head longer 

 than broad, slightly attenuate in front, and having two foveae as well 

 as strong, nearly straight sulci joined with a frontal transverse sul- 

 cus, placed behind the eyes, vertex slightly convex, sinuate behind 

 and incised in the middle ; antennae short, thick, first joint sub- 

 elongate, subcylindrical, second briefly ovate, third globose, slightly 

 transverse, intermediate ones different in each sex, eleventh short, 

 truncate at base, acuminate at apex ; prothorax a little broader than 

 the head, subcordate, and having the sides crenulate, lateral foveae 

 distant from the margin and much larger than the median one, 

 transverse sulcus hardly deep, slightly angulate in the middle, base 

 with several small foveae ; elytra a little broader than the prothorax, 

 much longer than broad, subparallel laterally with the shoulders 

 rounded, bifoveate at base, sutural stria entire, the dorsal one

 elytra, first dorsal segment impressed transversely at base, last dorsal 

 one quadrate at apex.

 broad as the preceding ones, produced inwardly, very transverse, 

 the fifth one thicker than the fourth, sixth to eighth transverse, 

 nearly equal in size to the third one, ninth a little larger, transverse, 

 tenth broader and thicker than the ninth ; apical margin of the third

 versely depressed at base ; metasternum depressed ; elytra not 

 attenuate at base and with the shoulders quadrate. Length
