tive of specific difference in the Malacodermata, and it is from a different locality ; 
also closely allied to D. discoideus *. 
Dromanthus jucundus (p. 123). 
_ A second example of this species was subsequently found by Mr. Champion at 
Bugaba: this one is rather larger than the type, being five millimetres in length, 
apart from the three segments of the abdomen which pass the elytra, and from which 
I infer the specimen is a female. The head and breast. are steel-blue, the abdomen 
yellow. In the type the two segments of the abdomen which are uncovered are 
bluish black. Both specimens were captured flying about timber in the forest. 
HELCOGASTER ? (to follow the genus Dromanthus, p. 122). 
Helcogaster, Boheman, Kongliga Svenska Fregatten Eugenies Resa, Zool. i. p. 81 (1858). 
A genus of Melyride, founded by Boheman upon three species from Australia, some- 
what resembling Lemphus and Carphurus, but with five-jointed tarsi, and (in some 
species) pectinated antenne. The only recently added species is one from Honolulu, 
described and figured by Dr. Sharp in ‘The Trans. Royal Dublin Society,’ iii. series 2, 
p. 157, t. iv. fig. 20, Helcogaster pectinatus. The admission into the genus of this 
species and of the one here described must be considered only tentative at present. 
They are, however, very clearly allied to the Australian species, and, as far as I have 
been able to examine them on the limited number of specimens, have no other very 
near ally. 
They may be known from small Malachiide by the hairy antenne and abdomen. 
1. Helcogaster (?) atratulus. 
Aterrima, nitida, fere glabra; antennis serratis, articulo basali rufo; capite punctato, fronte ineequali ; 
antennis articulis singulis intus, abdominisque apice, villosis. Long. 3 millim. 
Hab. Panama, Tolé (Champion). 
Var.? Minor; antennis tenuioribus, articulis duobus basalibus rufis; elytris piceis. 
Hab. GuaTEMALA, near the city (Champion). 
This small insect, of which there is only a single specimen from each of the 
* Dromanthus discoideus. 
Niger, nitidus; elytris opacis, prothoracis lateribus femoribusque basi rufo-testaceis; antennis fortiter serratis, 
articulis tribus basalibus subtus flavis. Long. 44 millim. 
Hab. Sourn America, Parana (coll. Gorham). 
In general appearance very similar to D. laticornis and D. nitedicollis described above, the most apparent 
difference being that the thorax has the disc entirely black, leaving only the margin (and that most widely in 
front) yellow. The antenne are not so wide as in D. laticorms.
