rounded and advanced as far as the apex of the median lobe. Labial palpi 

 3-jointed ; basal joint slightly longer than wide, cylindrical ; second much 

 shorter, very small, cylindrical ; third longer, subulate. Muxillve moderate, 

 not exserted ; lobes small, the outer enveloping the inner, not hooked at apex, 

 ciliate. Maxillary palpi nearly of the usual type, ratlier slender ; second and 

 third joints subequal ; fourth subulate. Under surface of head without trace 

 of lateral carinse. 



Prothorax rather short. Pronoiiim transverse ; apex truncate ; base just 

 visibly arciiate ; sides feebly arcuate and just perceptibly convergent from 

 base to apex ; basal angles nearly right and extremely narrowly rounded ; 

 flanks rather shallow, very strongly deflexed, the lower edge straight, the 

 apical angles — viewed laterally — more broadly rounded than the basal. Hypo- 

 mera very strongly intlexed, almost parallel to the pronotal flanks. Prosienmin 

 extremely short before the coxae, the latter large. 



Mesothorax short. Scutellum triangular, strongly transverse, the apex ex- 

 posed. MesoMei-nal parapltura. small, the epimera but partially developed, 

 leaving a considerable extent of membrane exposed adjacent to the elytral 

 humeri. Coxk moderate and not greatly exserted, the cavities confluent. 



Metathorax longer. Elytra transverse, truncate at apex, as wide as, and 

 with the suture subequal in length to, the pronotum, not connate ; suture 

 not beaded ; hind wings apparently not well developed ; apical edge slightly 

 inflexed and membranous ; flanks without true epipleurse, not beaded. 

 Metasteitial episterna very wide behind, their inner line tangent to the elytral 

 humeri. Coxce rather narrow, extending to the very wide episterna, contiguous. 



Abdomen slightly wider than the elytra, the sides feebly arcuate, consisting 

 of six segments. Upper surface flat, each segment with a single apical series 

 of long stiff setfe ; border wide, bi;t not inclined. Lower surface convex, the 

 sets shorter and not definitely arranged. 



Legs short and robust. Femora oblong, deeply excavated along the lower 

 edge toward apex for the reception of the tibiae, the latter nearly equal in 

 length to the femora, parallel, truncate or slightly rounded at apex, more 

 finely pubescent, entirely devoid of terminal spurs or spinules, but having 

 several very long stifi" setse along the external edge. J'arsi short, rather 

 robust, pubescent, 4-jointed on all the legs, the first joint of the posterior as 

 long as the next two together and equal in length to the fifth. Ungues very 

 small, arcuate. Anterior tarsi with a better defined tuft of long hair beneath 

 each joint. 



There is no described genus known to me with which the present 

 can be compared. The robust compact cylindrical antennae are 

 characteristic of a number of terraitophilous and myrmecophilous 

 genera, but none of these appears to have the posterior tarsi four- 

 jointed, as they very clearly are in Abroteles. 



A. Beaiimonti n. sp. — Pale piceo-testaceous ; abdomen flavate ; integu- 

 ments polished, not perceptibly punctate. Head very finely, sparsely pubes-
