RUTELIN^: 51 



Scutellum more or less sparsely punctate, the prothorax almost as long 

 as wide 5 



5 Form more abbreviated and rhombiform, shining, the type dark tes- 

 taceous throughout, the elytra rather more pallid, the head and pro- 

 notum with feeble violaceous lustre, the latter blackish along the 

 sulcus; legs pale, the hind tarsi blackish, the hind femora more 

 flavate; head scarcely half as wide as the prothorax, unusually 

 coarsely and deeply punctato-rugose, the sculpture abruptly sub- 

 obsolete near the eyes; clypeus moderately reflexed and submetallic 

 peripherally; antennae black, the club not as long as the five pre- 

 ceding joints; prothorax a fifth or sixth wider than long, the sides 

 feebly subprominent near the apex, the basal angles moderately 

 rounded, the apical blunt at tip; basal bead strong, very narrowly 

 interrupted at the middle; surface deeply sulcate medially from apex 

 nearly to the base, moderately and rather sparsely punctate, more 

 strongly laterad, the oblique fossae strong, the surface between 

 them rugose, the external pit distinct; scutellum sparsely and un- 

 evenly but distinctly punctate, the sulcus wanting except post- 

 medially; elytra barely longer than wide, rather less than one-half 

 wider than the prothorax, unusually rapidly narrowing and with 

 arcuate sides from base to apex, the lateral edge and next ridge 

 swollen basally; ridges equal discally, the sulci with distinct trans- 

 verse lines across the bottom; pygidium in profile evenly sloping, 

 becoming vertical at tip through an unusually short distance or 

 feebly pointedly tumid only very near the apex, the surface very 

 shining, glabrous, the transverse sculpture shallow, rather fine and 

 much less close-set than in the preceding. Length (9) 12.0 mm.; 

 width 5.3 mm. Nicaragua (Omitepe), Shimek. *convergens n. sp. 



Form more oblong-oval, shining, deep black, the legs partially rufescent, 

 the hind femora pale on the upper margin and in a slender lateral 

 streak basally; head feebly metallic, slightly pallescent anteriorly; 

 pronotum deep black, without trace of metallic lustre, the elytra 

 wholly pale yellow-brown; head feebly convex, discretely punctate 

 basally, the clypeus less than twice as wide as long, trapezoidal, 

 with rounded angles and very feebly reflexed edges; antennal club 

 oval, a little longer than the five preceding joints; prothorax very 

 nearly as long as wide, the sides almost evenly, feebly arcuate, the 

 prominent apical angles but finely blunt at tip, the basal broadly 

 rounded, the basal bead strong, widely and completely effaced 

 medially; surface smooth, with rather close moderate punctures at 

 the apical margin, a little coarser at the sides, elsewhere subobsolete, 

 the fossae large, deep and smooth, the external pit confluent with the 

 posterior fossa; scutellum with a shallow rugulose sulcus, elsewhere 

 minutely, very sparsely punctate; elytra large, a third longer than 

 wide, gradually moderately cuneiform, with broadly arcuate sides, 

 the edge thickened basally, not quite one-half wider than the pro- 

 thorax, very evenly costate and sulcate, the transverse lines at the 

 bottom of the sulci very even and distinct; pygidium shining, the 

 transverse lines straight, very deep, rather coarse, moderately 

 separated and not interlacing, the erect pale hairs stiff and sparse;
