eyes prominent, coarsely facetted. Thorax elongate, deeply con- 

 stricted in the middle. Hind coxae separated by a broad process of 

 the basal ventral segment ; basal ventral segment very elongate ; legs 

 elongate, femora simple and not clavate. Elytra not covering the 

 pygidium. The insect is most allied to Tomoderus compressicollis, 

 and should be classed between Formicomiis and Tomoderus, in the 

 Anthicides. 



Pachtcotes ventralis, n. sp. 



Fusco-ferrugineus, opacus, crassiusculus, subcylindricus, elytris 

 minus elongatis, crenato-striatis, interstitiis rugosis, parte apicaJi setis 

 parcis erectis fulvis instructd. Long. 4i\ mm. ; lat. 2 mm. 



Antennge moderately long, basal joint elongate, 2nd very short, 4 — 7 very short 

 and very closely packed, 8—11 formhig a rather large but little flattened acuminate 

 club. Head very short, large, rather coarsely and closely punctured. Thorax about 

 as long as broad, a good deal narrowed towards the front, coarsely punctured, with a 

 very narrow space along the middle forming an obsolete carina. Elytra rather short, 

 coarsely sculptured, the apical part bearing distinct erect tawny hairs. 



Hiccarton, a single individual found by Mr. "Wakefield. 



After an examination of this specimen, which belongs to the 

 ScohjtidcB, its exact affinities appear to me so doubtful that I have 

 given it a new generic name. The club of the antennae is rather 

 large and but little flattened, covered with hairs, but these do not 

 extend over the whole surface, so that the four joints can be dis- 

 criminated. Eyes moderately coarsely granulated, very distant on 

 the vertex, transverse, separated from the antennae by a rather deep 

 constriction. Anterior coxa) distinctly separated, middle coxae broadly 

 separated. Ventral segments rather short, the basal one peculiarly 

 prominent, as long as the three following short ones together, these 

 being about equal inter se and separated by very deep sutures. Tibia) 

 not stout, moderately broad at the apex, with their outer edge and 

 apex denticulate, their front face rough, their posterior one pubescent 

 (not smooth or excavate) ; tarsi slender, lobes of the third joint but 

 little developed. The insect has the form and appearance of Hylurgus 

 ligniperda, but is rather shorter and thicker, but the granulation of 

 the eyes is distinctly coarser, and the peculiar pi'ominence of the basal 

 abdominal segment suggests an early stage of Scolytus-AxRevQW' 

 tiation, to which genus however its relationship is otherwise 

 quite remote ; I think for the present it may be placed near 

 Hylurgus ligni])erda.
