rounded and advanced as far as the apex of the median lobe. Labial pa/pi 

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

 sliorter, very small, cylindrical ; third longer, subulate. Muxillce moderate, 

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

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

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

 of lateral carinas. 



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

 visibly arcuate ; 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, tlie 

 apical angles — viewed laterally — more broadly rounded than the basal, tiypo- 

 mera very strongly inflexed, almost parallel to the pronotal flanks. Prosternum 

 extremely short before the coxse, the latter large. 



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

 posed. Mesostemal parapleune small, the epimera but partially developed, 

 leaving a considerable extent of membrane exposed adjacent to the elytral 

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



Metuthorax 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 epipleurae, not beaded. 

 Metasternal 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 stifl" setje ; border wide, but not inclined. Lower surface convex, the 

 setae shorter and not definitely arranged. 



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

 edge toward apex for the reception of the tibije, 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 stifl" setae along the external edge. 7'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 termitophilous and myrmecophilous 

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

 jointed, as they very clearly are in Abroteles. 



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

 ments polished, not 2>erceptibly punctate. Head very finely, sparsely pubes-
