HOMALOTA. 179 
usually separated, and the mesosternal process is comparatively broad, and its extremity 
is rounded and quite distinct. I think its best position at present would be in the 
H. xanthoptera group. 
14. Homalota semiobscura. 
Parum elongata, nigro-fusca, elytris fusco-testaceis, antennarum basi pedibusque sordide testaceis; antennis 
parum elongatis, sat crassis, articulis penultimis leviter transversis; prothorace transverso; abdomine 
apicem versus subattenuato, subtiliter parum crebre punctato. 
Long. 2 millim. 
Hab. GuateMAa, Capetillo (Champion). 
Antenne slightly thicker externally; third joint rather short, shorter than second ; 
fourth about as long as broad, it and the two or three following joints scarcely at all 
different from one another, the tenth slightly transverse; terminal joint rather large, as 
long as the two preceding together. Head subcircular, a good deal narrower than the 
elytra. Thorax rather strongly transverse, the base a good deal rounded, the sides 
behind but little rounded, at the front angles much deflexed, the surface very finely 
and indistinctly punctate. Elytra longer than the thorax, finely punctate. Hind body 
rather short, its punctuation fine, sparing, and indistinct. 
This obscure insect resembles in size and form the European ZH. atrata, Man.; but 
the hind body is less punctate; the intermediate coxe, though approximate, are not 
quite contiguous. Only one individual has been found. 
15. Homalota spergula. 
Nigerrima, pedibus fuscis ; antennis minoribus, extrorsum haud incrassatis, articulis 4°-10™ leviter transversis ; 
prothorace transverso ; elytris abdomineque crebre fortiter punctatis. 
Long. 2 millim. 
Hab. Guatemaa, San Gerénimo 3000 feet (Champion). 
Antenne small and not incrassate externally, third joint shorter than second; fourth 
small, almost or quite as long as broad ; fifth to tenth short, transverse, but not strongly 
so, terminal joint not large. Thorax rather strongly transverse, rounded at the sides, 
not much rounded at the base, and not narrowed in front. Elytra small, longer than 
the thorax, roughly punctured. Hind body parallel, all the segments with a rather 
rough punctuation, exserted sete very insignificant. Legs dilute blackish or smoky, 
short, middle and hind tibie each bearing an exserted seta. 
This insect is very similar to the European H. nigra, but is a little smaller, and has 
the elytra and hind body more roughly punctate. Only a single individual, badly 
preserved, has been found; it is possibly a male, the hind margin of the seventh dorsal 
plate being truncate. The middle coxe are distinctly separated, though the interval 
between them is not great.
