 Proculejus Sartorii, Kaup, 18686, p. 17. 



One specimen without locality record. Length 12*5 mm. 



The labrum is concave in front, but not so strongly as in P. pubicostis. The clypeus is 

 straight or lightly concave, and is united with the well developed frontal tubercles a little 

 distance from each end. The frontal tubercles are united by well developed frontal ridges 

 to the central tubercle, which is situated a little in front of the middle of the head ; this- 

 tubercle is small and upwardly directed, and has no free apex. The scutellum is sparsely 

 and somewhat finely punctured, especially in front. The mesothoracic episterna are 

 punctured except in the posterior angles, and are glossy except for an oval patch behind the 

 lower margin. In all other respects this species resembles the last, except that the 

 mesosternal scars are shallower and that the elytral grooves are if anything even more 

 coarsely punctured. 



Proculejus truquii, Kaup. 

 Proculejus Truquii, Kaup, 18686, pp. 16-17. 



One specimen frcm Mexico, 31 mm. long. 



Proculejus truquii is much broader in proportion to its length than is either of the two 

 preceding members of the genus. The head is ornamented much as in P. sartori, but the 

 frontal area is somewhat narrower and the central tubercle is situated more in the middle. 

 The pronotum resembles that of the two preceding species. The scutellum bears a few 

 obscure punctures. The grooves of the elytra are very much broader and more coarsely 

 punctured than in either of the preceding species, being about as wide as the ribs at the sides, 

 and about half as wide above, the punctures in each groove being much broader than the 

 spaces between them. In all other respects P. truquii resembles P. sartori. 



Subfamily PROCULIN AE. 



Almost all members of this subfamily have the clypeus exposed as in the 

 Pseudacanthinae ; but it is fused with the frons instead of separated from it by a distinct 

 suture. Faint traces of this suture, as of the outer tubercles, may perhaps be recognized in 

 the genus Arrox, which is probably the most primitive genus of the family. From this genus 

 the extensive genus Veturius may easily be derived ; and this appears to have given rise to 

 two divergent lines of descent, culminating respectively in the flightless genera Platyverres 

 and Proculus. The former, in which the clypeus is completely hidden, is connected to 

 Veturius through the genus Verres, in which all stages of the disappearance of the clypeus 

 may be traced (compare fig. v, 11-15, p. 34). The latter, in which the specialized 

 features associated with flightless species 1 reach their highest development, has the clypeus 

 exposed, and is connected to Veturius by the genus Publius, a genus which only differs 

 from species of Veturius with the two lowest terminal teeth fused by its fused elytra and 

 reduced wings.
