the coxae, and its anterior line is only very feebly arcuate behind 

 the narrow intercoxal space. The surface between the metasternum 

 and the mesosternal process is occupied by a large and long subtri- 

 angular isthmus, moderately compressed anteriorly, where it extends 

 under the apex of the latter, and subtubercularly elevated at its 

 centre. This is probably the structure also in qxiadricollis, but in 

 the type of that species these parts are concealed, 



TARPHIOTA n. gen. 



Body subparallel, moderately wide, flattened above, opaque. 

 Head well inserted, very slightly constricted at base, the eyes 

 rather large and somewhat convex; labrum transverse, truncate; 

 infralateral carina completely wanting. Antennae slender, filiform, 

 scarcely visibly enlarged near the apex, setose, moniliform, the 

 joints generally held slightly asunder by the narrow cylindrical 

 basal peduncles; first three joints rapidly decreasing in length, the 

 first thicker ; four to six equal in width, the former slightly elon- 

 gate-oval, the latter subglobular ; seven to ten feebly transverse and 

 just visibly increasing in width ; eleventh as long as the two pre- 

 ceding, conoidal, compressed at tip. Mentum ample, trapezoidal, 

 the apex rather broadly, feebly produced and feebly sinuato-trun- 

 cate in the middle. Ligula with a deeply bifid process and two 

 discal setae, the labial palpi three-jointed, the first and last joints 

 longer than the intermediate. Maxillary palpi with the third joint 

 a little longer than the second ; fourth distinct, rather stout, bulbose 

 at base and apparently with an excessively minute bisetose apical 

 appendage. Prothorax transversely subquadrate, narrower than 

 the elytra, the hypomera feebly inflexed, broadly triangular and 

 greatly visible from the side. Elytra greatly developed. Abdo- 

 men linear, the first four tergites impressed at base, the first two 

 rather more strongly ; fifth just visibly longer than the fourth. 

 CoxsB moderately large, the intermediate extremely approximate 

 but not contiguous, the mesosternal process long, finely acute and 

 attenuate, extending two-thirds of their length, the metasternal 

 process acutely produced beneath the mesosternal, the coxae well 

 imbedded. Metasternum large, the side-pieces narrow, the inner 

 margin arcuately approaching close to the elytra posteriorly. Legs 

 rather short, somewhat stout ; anterior and middle tibiae strongly 

 spinose externally ; tarsi 4-5-5-jointed, the posterior three-fourths 

 as long as the tibiae, with the first four joints slightly elongate and
