at the apex. The prosternum is broadly, subhorizontaliy produced behind, the apex 
being deeply excavate beneath for the reception of the convex, declivous mesosternum, 
the latter having a long, oblique groove on either side. The intermediate coxal 
cavities are widely open externally, the trochantin being large and prominent. The 
hind coxe are transverse. The intercoxal process of the abdomen is narrow, triangular. 
The head in repose is so deeply sunk into the prothorax that the eyes are partly hidden ; 
the epistoma is large and separated from the front by a very faintly impressed line. 
The tibial spurs are short. 
1. Ennebeus uniformis, (Tab. XXIII. figg. 4; 4a, antenna.) 
Elliptic, convex, shining, pitchy-black, the head, and sometimes the base, suture, and apex of the elytra 
indeterminately, ferruginous ; above and beneath very densely, minutely punctured, and uniformly clothed 
with pruinose greyish pubescence. Antenne rufo-testaceous, very slender, the joints 9-11 forming a 
narrow club—9 triangular, slightly longer than broad, 10 as broad as long, 11 a little longer than 10; 
prothorax strongly transverse, the sides rounded and converging from the base; elytra very closely fitting 
to the base of the prothorax, and at the sides forming almost a continuous outline with it, usually with 
very indistinct rows of shallow, coarser punctures on the basal half towards the suture; beneath pitchy- 
brown, the epipleure more or less ferruginous ; legs rufo-testaceous. 
Length 3-32 millim. 
Hab. Panama, Volcan de Chiriqui 4000 to 5000 feet (Champion). 
Four examples. Extremely close to HL. ovalis, Wat., but more convex and slightly 
smaller, the antenne with the apical three joints less widened and more elongate. 
2. Ennebeus marmoratus. 
Elliptic, convex, shining, pitchy-black, the head rufous, the sides of the prothorax anteriorly, the humeri, and 
the apices of the elytra obscure ferruginous, the antenne and legs rufo-testaceous, the femora and tibiz 
slightly darker; above and beneath very densely, minutely punctured; the upper surface pruinose- 
pubescent, the elytra with irregular dark brown spots which tend to form fasciz. Antenne slender, 
joints 9-11 forming a rather broad club—9 triangular, as long as broad, 10 and 11 transverse ; 
prothorax moderately transverse, rapidly narrowing from the base; elytra with faint irregular rows of 
coarser, not very closely-placed punctures on the basal half towards the suture. 
Length 4 millim. 
Hab. Mexico, Jalapa and Misantla (Flohr). 
A single specimen of this species has been forwarded to us by Mr. Flohr. Larger 
and broader than EF. wniformis, the thorax less transverse, the club of the antennee 
shorter, the serial punctures on the disc of the elytra a little more distinct, and the 
pubescence of the upper surface not uniform in colour, but interrupted by dark brown 
spots which tend to form fascie. <A closely allied species occurs in Colombia *. 
* Ennebeus seriatus. 
Pitchy-black or pitchy-brown, the antenne and legs obscure rufo-testaceous, above and beneath very densely, 
minutely punctured ; the pubescence of the upper surface pruinose, that on the elytra yellowish-grey,
