174 Arthur M. Lea: 



Antennae considerably thinner than in curvicornis, when 

 viewed from the sides almost straight, and, when cnt across in 

 any part of their leng-th. circular in section ; the abdominal 

 tubercles also are not as in that sj^ecies. The general appear- 

 ance is much like Jiamatipes, and the antennae are very 

 similar, but the abdominal fovea and legs are different. 

 Biparfifus is similar in many respects, but also has abdomen 

 and legs different and much more clothing. 



Articerus ri/Iuidricoriils, n.sp. (Figs. 8, 42.) 



<?• Reddish-castaneous, greater portion of each elytron some- 

 what paler. Head and prothorax with short depressed setae, 

 resembling scales, elytra with longer but still depressed setae, 

 condensed into a feeble fascicle at the middle of the apex of 

 each ; abdomen with sparse suberect setae, and with a long 

 loose fascicle on each side of base; with'a ridgfe of setae along 

 middle of metasternum. 



Head about twice as long as wide, without median impres- 

 sion ; eyes less prominent than usual. Antennae cylindrical, 

 not much longer than head, base narrow, apex circular in out- 

 line, surface with nuujerous small granules. Prothorar not 

 much wider than long, front angles strongly rounded, basal 

 two-thirds almost parallel-sided ; medio-basal impression absent 

 or extremely feeble ; punctures as on head. Elytra with dense 

 punctures, becoming sparser on disc ; sutural stria distinct. 

 Abdomen with basal fovea large and strongly continued hind- 

 wards, internally at base rather suddenly deepened, then to- 

 wards each side with a feeble oblique ridge ; under surface 

 largely excavated but not foveate, base strigose towards sides. 

 Metasternum obtusely ridged along middle, with two small 

 apical teeth. Trochanters minutely dentate ; femora rather 

 thin ; tibiae flattened, front pair feebly dentate at about apical 

 third, middle pair strongly mucronate at apex. Length 2^ mm. 



? . Diffei's from male in having under surface of abdomen 

 evenly convex, trochanters not dentate, front tibiae narrower 

 and not dentate and middle pair not mucronate.
