HOMALOTA. 181 
subsequalibus ; prothorace transversim subquadrato, cumque elytris crebre subasperato-punctatis ; abdomine 
apicem versus subattenuato, crebre et fortiter (apicem versus parcius) punctato. 
Long. 21-3 millim. . 
Hab. GuateMaa, San Gerénimo, Guatemala city, Capetillo and San Joaquin in Vera 
Paz (Champion). 
This species is similar to the European Z. longicornis, Grav., but is smaller and has 
less elongate antenne. These organs are large and black, the basal joint being a little 
marked with yellow, the second and third joints subequal, the fourth a little narrower 
than the fifth but much shorter than it; the fifth to tenth subequal, each subquadrate, 
being only a little narrower at the base than at the apex, the fifth slightly longer than 
those following, which are distinctly transverse. Head very obtuse in front. Thorax 
longer than broad, straight at the sides, hind angles obtuse; surface rather shining, with 
a fine but rather rough punctuation. Elytra a good deal longer than the thorax, with 
similar punctuation to it. Hind body shining, rather roughly punctate and setose; the 
basal three segments closely punstate, the following more sparingly. 
In the male the seventh dorsal plate has, behind, four short widely separated teeth ; 
the two central ones are very short and obtuse, and separated by a gently curved 
emargination ; the lateral ones scarcely project further back than the central ones, but 
_ are longer, because the incision between them and the central teeth is deeper. 
According to a note of Mr. Champion’s, this species is found in dung in the mountains. 
It can be readily distinguished from its allies by the comparatively small fourth joint of 
the antenne. Its appearance and superficial characters are intermediate between those 
of the European H. longicornis and H. cinnamoptera, Th.; the mesosternal process, 
however, is less elongate than in those species, and the metasternal one is rather more 
elongate; the two processes are separated by an intercoxal isthmus of about the same 
length as in the European insects above named; but this is placed more in front ; there 
is a very short and fine longitudinal carina on the front of the mesosternum in the 
middle.

Nigra, pedibus elytrisque testaceis ; antennis elongatis, articulis 4°-10™ haud transversis ; prothorace transversim 
subquadrato, cumque elytris crebre punctatis; abdomine apicem versus angustato, basi sparsim, apice 
adhuc parcius punctato. 
Long. 24-3 millim. 
Hab. Guatemauta, San Gerdnimo, Capetillo (Champion); Nicaragua, Chontales 
(Janson). 
Fourth joint of antenne elongate, longer than broad, about equal to the following 
joint; fifth to tenth similar to one another in length, each scarcely broader than its 
predecessor, the fifth longer than broad, tenth about as long as broad; terminal joint 
rather elongate, equal to the two preceding together. Thorax not strongly transverse,
