Van Duzee lias treated calidus, Walk., as a distinct species, 

 in which he has been copied by Kirkaldy. Van Duzee 

 writes: — " This species is easily distinguished by its bright 

 reddish tint, the broad blackish submargins and median 

 line of the pronotum, the dark scutellnm with imperfect 

 median line and the large pale cali in the angles, and the 

 conspicuous black ray on the disk of the elytra." These, 

 however, are not the characters found in Walker's type, and 

 are more characteristic of typical armatus. In calidus the 

 black median fascia and submargin to the pronotum are much 

 narrower, not broader; the callose basal spots to scutellum 

 vary in size in different specimens, in some the broad black 

 median band to the pronotum is continued through the 

 scutellum. 



The calidus, Walk., is only a varietal form of a variable 

 species. 



Eumecopus alexandrianus, sp. n. 



Head purplish brown, three longitudinal fascise at base 

 extending to a little before eyes, and in front of these the 

 margins of the central lobe, basal halves of lateral margins 

 in front of eyes, basal margins of eye-, and a basal .*pot 

 before eyes ochraceous, lateral lobes a little transversely 

 wrinkled and punctate, tlnir outer margins sinuate and 

 slightly recurved ; antennae reddish testaceous, apices of 

 second and fifth joints and base of fourth ochraceous, second 

 joint subequal in length to third, first lougly passing apex 

 of head, slightly thickened and curved, fourth slightly longer 

 than third, distinctly longer than fifth ; pronotum purplish 

 brown, very coarsely punctate and iirorate with ochraceous 

 markings, the anterior and lateral areas more finely punctate, 

 lateral margins strongly concavely sinuate, obscurely crenu- 

 late near apices, posterior angles strongly spinously produced, 

 a l.ttle upwardly recurved ; scutellum dark purplish brown, 

 irroiated with ochraceous, slightly rugulose, coarsely thickly 

 punctate, a levigate spot at each basal angle, a smaller 

 central basal spot and ihe apex broadly ochraceous ; corium
