DYNASTIN^E 243 



strongly, closely punctured throughout; mentum evenly and strongly 

 convex, the punctures medially smaller and sparser than toward the 

 sides. Length (cf) 34.0 mm.; width 17.2 mm. Honduras (San 

 Pedro Sula). A single male, at or a little under the median stage of 

 development *frontalis n. sp. 



7 Body more oval and smaller in size than in any other of this section of 

 the subgenus, convex, shining, pale castaneo-rufous above and be- 

 neath, the head and anterior parts of the pronotum more obscure; 

 head larger, slightly less than one-half as wide as the prothorax, 

 with somewhat larger eyes than in the female of julianus and others, 

 they being separated by but little more than twice their own width, 

 the rugosity dense, coarser basally, the base very evenly and trans- 

 versely, abruptly smooth and polished; tubercles strong, rounded, 

 separated by two-fifths the interocular width; clypeus narrowly 

 truncate and feebly though abruptly reflexed at tip; mandibles 

 with the two anterior teeth distinct, the posterior occupying nearly 

 half the entire edge but only very feebly arcuate; antennal club as 

 long as the preceding six joints; prothorax relatively smaller and 

 especially shorter than in the allied species, one-half wider than long, 

 the apical sinus broader and shallower than usual and nearly three- 

 fifths as wide as the base, the outline, sculpture and impressions other- 

 wise nearly as in the female of julianus and others; scutellum similar; 

 elytra more oval, more strongly rounded in fully apical half, slightly 

 longer than wide, almost a third wider than the prothorax and slightly 

 more than twice as long, the nearly sculptureless surface as usual, 

 except that, toward the sides, feebly defined series of very small 

 punctures become evident; pygidium as usual, very short and trans- 

 verse, strongly, transversely tumid submedially and punctured and 

 pubescent above, the hairs very long and stiff; hind coxal plates 

 sharply reflexed peripherally, near which the coarse separated punc- 

 tures are replaced by fine, close, subscabriculate sculpture. Length 

 (9) 30.0 mm.; width 16.5 mm. Texas. A single specimen. 



tarsalis n. sp. 



8 Body oblong-suboval, stout, convex, shining, black, the elytra very 

 dark castaneous, the under surface paler; head well developed, more 

 than two-fifths as wide as the prothorax, the eyes separated by barely 

 twice their width, the rugosity basally, as well as on the clypeus, 

 consisting of widely separated small asperulate elevations; tubercles 

 rounded, high, separated by one-half the interocular width; clypeal 

 apex obtuse, nearly as broad as the distance between the tubercles 

 and strongly, evenly arcuate, gradually and very moderately re- 

 flexed; mandibles externally nearly as in the female of julianus, the 

 middle tooth a little higher; antennal club not as long as the pre- 

 ceding six joints; prothorax throughout nearly as in Julian us, except 

 that the oblique sides, before the rather narrowly rounded median 

 arcuation, are broadly and feebly but more obviously sinuate; 

 scutellum similar but more sharply ogival, with less arcuate sides; 

 elytra as in julianus but broader, more than a fourth wider and four- 

 fifths longer than the prothorax, rounded in less than apical half; 

 pygidium of the usual form but with the transverse tumidity less
