groups of which the one is remote from the apex, the other is very 

 near the base, the distance between the two being larger than the 

 distance from the apex, apical spurs very small, both somewhat 

 longer than the strongly abbreviated first tarsal joint ; hind coxae 

 with distinct punctures, the bristles near the outer margin here 

 rudimentary, the sternum, especially in the middle anteriorly convex 

 and with a weak impression on the smooth part ; anterior tibiae 

 narrow in both sexes, the first two teeth remote, the third rudi- 

 mentary ; joints 3-7 of antennae moniliform, small but distinct, 

 club testaceous yellow, fairly strong, somewhat curved and some- 

 what shorter than the pedicel ; the brush-like clothing of the mentum 

 consists of pale-yellow laminae between which some hairs are pro- 

 jecting. This not very striking but very peculiar species reminds 

 one of the smaller C amenta species, which differ, however, by their 

 short hind coxae." 



ALLOKOTAESA, n. gen., 



Plate XLVL, fig. 4; figs. 15, 15a. 



Buccal organs of S erica ; clypeus suddenly narrowed laterally, 

 with the anterior margin tri-dentate, only half as wide as the head 

 in the frontal part, and having a median transverse keel running 

 parallel to the arcuate, very shallow frontal suture, genae long ; 

 antennae 10- jointed, third shorter than fourth and fifth, these 

 three joints seemingly partially fused together, sixth and seventh 

 very short, compressed, club 3-jointed, very little shorter than the 

 whole pedicel in the male ; prothorax short, sparingly setulose 

 laterally ; scutellum acuminate ; elytra nearly cylindrical, pygidium 

 convex, triangular; abdomen plainly compressed somewhat in the 

 manner of some Heterochelus of the Sub-family Hopliina; hind 

 margin of coxae arcuate, covering the greatest part of the third 

 segment ; anterior tibiae tri-dentate outwardly, the basal tooth, how- 

 ever, is very small, the anterior tarsi are short, the intermediate and 

 posterior long, in the male they are abnormally developed into sub- 

 triangular lobes decreasing in width from the basal to the apical joints, 

 and with the three basal wider or as wide as the tibia, the claws 

 are almost filiform, cleft, however, at the apex, the outer one is twice 

 as long as the inner ; the intermediate and posterior tarsi and claws 

 are normally shaped as in the female ; the spurs of the hind tibiae 

 are slightly longer than the basal joint which is one-third shorter 

 than the second ; in the male the inner spur of the anterior tibiae 

 has disappeared, but it is strongly developed in the female.
