visible in the sinus, rounded behind. Length (cf ) 22.0 mm.; width 



i i.o mm. Honduras (San Pedro Sula) *composita n. sp. 



Ligula shorter and broader; body more oblong-oval and in general without 

 metallic lustre as in 'the succeeding species: clypeus (cf ) with 

 rounded, broadly converging sides, twice as wide as long, the apex 

 broadly arcuato-truncate, with broadly rounded angles, about two- 

 thirds as wide as the base and only very finely and feebly reflexed, 

 or ( 9 ) less transverse, trapezoidal, with straighter sides and more 

 narrowly truncate and distinctly reflexed apex, which is barely more 

 than half as wide as the base, rather closely, strongly punctate, 

 more finely in the male, the remainder finely and sparsely punctate, 

 rather more strongly toward the middle of the front; antennal club 

 shorter than the stem but not greatly so in the male, differing but 

 little sexually; prothorax fully twice as wide as long, in outline nearly 

 as in the preceding and with similar ambient bead, but with blunter 

 apical, and much less rounded basal, angles, very finely and sparsely 

 punctate, the punctures stronger, closer and more or less mingled 

 with minute punctulation laterad; scutellum nearly smooth, entirely 

 black with metallic gloss, to pale with metallic black margins; elytra 

 each with three black dots, together nearly a third longer than wide, 

 barely wider than the prothorax, circularly rounded at apex, the 

 sides feebly arcuate, less so basally; surface minutely, remotely 

 punctulate, with feebly defined and irregular series partially visible, 

 the punctures suturally a little less minute, and, toward the sides, 

 mingled more or less closely with minute feeble punctulation; under 

 surface and legs wholly deep black with very feeble greenish lustre, 

 the porrect mesosternal process broad and obtusely rounded at tip; 

 pygidium with well separated transverse intermingling scratches 

 which become sparser apically. Male with the sixth ventral nearly 

 as in the preceding, smooth and very feebly impressed; female with 

 the fifth ventral not modified, the sixth nearly smooth, the surface 

 apically with two tumidities, separated by an anteriorly narrowing, 

 moderate and but feebly sculptured concavity, the pygidial margin 

 slightly broadened medially on its under surface as usual, the pale 

 supplementary coriaceous seventh segment of the male not visible. 

 Length (cf 9 ) 20.8-24.0 mm.; width 11.5-13.0 mm. New York 

 and Virginia to Michigan and Iowa. Abundant. Males much less 

 abundant than the females. [Scarabceus punctatus Linn.] 



punctata Linn. 



A Similar to the preceding but larger and especially much broader, 

 the elytra more inflated posteriorly, the anterior thoracic angles 

 more acute an ! sharp and the basal nearly similar, the sculpture 

 of the pronotum stronger and more confluent laterally and that 

 of the elytra with the shallow fine sculpture toward the sides dense 

 and almost confluent, the punctures toward the suture basally 

 much coarser and deeper; pygidium more densely and deeply, 

 intricately sculptured in transverse lines, the apex more narrowly 

 rounded and the sides much more sinuate; legs dark testaceous 

 throughout, the tarsi piceous. Female with the fifth ventral 

 concave medially at apex, the sixth with rather close-set sculpture
