Under a high power this species is seen to be wholly, but very minutely, strigose, 
but this sculpture is more evident on the sternal plates than above. The sutural stria 
is punctiform and not very distinct, and is much abbreviated in front. Unique.

Ovalis, subdepressus, niger, nitidus; fronte parce punctulata, minutissime et densissime strigulosa, transversim 
convexa, stria integra; pronoto antice vix dense punctulato, postice parum grosse punctato, stria integra ; 
elytris striis dorsalibus obsoletis, suturali valida, antice solum abbreviata; propygidio prave et profunde 
sulcato; prosterno minutissime et densissime striguloso, parce punctulato, immarginato, haud striato ;

Hab. British Honpuras, R. Sarstoon (Blancaneauz). 
The punctuation of the propygidium distinguishes this insect from its congeners ; and 
the usual vermiculations of the pygidium in the genus give place to wide and deep 
sulci. ‘The latter are confined to a somewhat ill-defined triangular area in the middle 
of the pygidium, leaving a transverse space at the base, which is only finely punctured. 
Unique.

Ovalis, convexiusculus, niger, nitidus, undique punctatus; antennis clava rufa; pedibus piceis; fronte pro-

minute et parce punctulato; pygidio punctulato, profunde vermiculato; prosterno parum lato, parce 
punctato et minutissime striguloso; mesosterno stria valida, biangulata, metasterno equaliter punctulato ; 
tibiis modice dilatatis, anticis 4-dentatis, intermediis 4-spinosis. Long. 2 millim. 
Hab. GUATEMALA, near the city (Champion). 
This species has a broader prosternum than any other in the present series. The 
metasternal strie are well marked, and they are connected with the marginal stria of 
the mesosternum., One example. 
12. Paromalus similis, sp. n. (Tab. VI. fig. 3.) 
Ovalis, convexiusculus, niger, nitidus; fronte parce punctulata, stria integra, ante oculos subconcava; pronoto 
punctato, stria completa, ante scutellum minute acuminato; elytris striis dorsalibus brevibus, suturali 
antice multum, postice parum, abbreviata ; propygidio transversim punctulato ; pygidio punctulato, 
grosse et profunde vermiculato; prosterno haud striato, minutissime et densissime striguloso, parce 
punctato; mesosterno stria valida modice biangulata, lateribus striato; tibiis antice parum contortis et 
dilatatis. Long. 24 millim.

This species differs from P. sobrinus in the prosternum being narrower, and
