PAROMALUS. 219 
The facies of this species resembles that of the elliptical and convex forms allied to 
P. mus, Mars., which occur under dead leaves and stones in the Eastern Archipelago. 
The strigose sculpture is exceedingly minute, and under the microscope is best seen on 
the sides of the thorax and on the metasternal plate. Sexual differences are not 
apparent in the two examples before us. 
92. Paromalus divaricatus, sp. n. (Tab. VI. fig. 5.) 
Ovalis, parum convexus, niger, nitidus; antennis pedibusque brunneis, clava rufa; fronte punctulata, stria 
tenuiter impressa; pronoto punctato, stria integra; elytris striis dorsalibus obsoletis, suturali nulla ; 
propygidio parce, pygidioque apice dense, punctulatis; prosterno haud striato, parce leviter punctato ; 
mesosterno stria transversa, biangulata; tibiis anticis 4-dentatis, intermediis spinulosis. Long. 2-23 
millim. 
Hab. GuateMata, near the city, Capetillo, Zapote (Champion). 
The pygidium is bistriate in one sex; the strie are fine and near the apex are some- 
what parallel to each other, and in the middle they part from each other at right angles ; 
the pygidium itself is reddish, and finely punctate, more densely so at the apex than at 
the base. The stria of the mesosternum is rather acutely, but not deeply, angulate on 
both sides, and the middle division of the stria is relatively very wide. Eighteen 
examples. 
93. Paromalus sagillatus, sp. n. (Tab. VI. figg. 6, 6a.) 
Ovalis, depressiusculus, niger, nitidus, punctulatus ; fronte pronotoque striis marginalibus integris ; elytris striis 
dorsalibus obsoletis, suturali nulla; propygidio postice parce punctulato ; pygidio (mas) in medio pro- 
funde triangulariter sulcato, (fem.) transversim bistriato; prosterno haud striato, magis lato ; mesosterno 
biangulato ; tibiis anticis 4-dentatis, intermediis spinulosis. Long. 2 millim. 
Hab. Mexico, Northern Sonora (Vorrison). 
This species is represented in the collection by two examples of opposite sexes. It is 
rather narrower than P. divaricatus, and the mesosternal stria has each of its divisions 
of equal breadth. The sulcus in the middle of the pygidium of the female is triangular 
and deep; in the other sex this sculpture is represented by two fine transverse striz, 
the apical one being straight, the other slightly bent. 
24. Paromalus sulcatus, sp.n. (Tab. VI. figg. 7, 7a.) 
Ovalis, depressiusculus, niger, nitidus, eoqualiter punctulatus ; fronte pronotoque striis marginalibus integris ; 
elytris striis brevibus vel obsoletis, suturali nulla; propygidio undique punctulato; pygidio profunde 
transversim sulcato; prosterno lato, parce punctato, haud striato, minutissime et densissime striguloso ; 
mesosterno stria acute biangulata; tibiis anticis 4-dentatis, intermediis spinulosis. Long. 23 millim. 
Hab. Guavemata, near the city, Calderas, Zapote (Champion). 
Four examples. Resembles the preceding species ; but the prosternum is not quite 
so broad, and the central division of the mesosternal stria is nearly equal to both the 
outer divisions. In what is presumably the female the transverse sulcus of the pygidium
