Diagnosis. — Head and pronotum without dense umbilicate punc- 

 tures, sometimes feebly margined beneath the eyes; antennae widely 

 separated at front of head, outer segments pubescent from the fourth 

 joint; labrum bilobed; palpi moderately slender, fourth segment of 

 maxillary longer than third, labial similar to maxillary ; gular sutures 

 not united or only posteriorly; pronotum virtually impunctate except 

 for longitudinal series, lateral margin double, the lines not united or 

 only in front; anterior coxal cavities entirely open behind; front 

 coxae large, exserted; posterior coxae contiguous, "triangular," 

 sometimes with a small expansion over the base of the trochanter; 

 first and second abdominal sternites absent ; intersegmental membranes 

 of abdomen with a pattern of irregular rounded sclerotized areas 

 arranged in longitudinal rows ; femora unarmed. 



Remarlis. — This genus is not distinguished from Bclonuchus by 

 characters of great importance or definiteness. The combination of 

 femoral armature and united gular sutures will distinguish the West 

 Indian species of Belonuchus, while in genefal they can be recognized 

 by a somewhat different appearance. 



A species was recently described by Bierig (1940) in this genus under 

 the name carihaeu^. A drawing of the head and pronotum was given,
