EUXENUS (p. 494). 



The generic name Euocenus (Faust, 1896) is preoccupied, and it has been changed 

 Euxmodes by Bovie [Ann. Soc. Ent. Belg. li. p. 67 (1907)1

MACRACALLES, gen. nov. (to follow the genus Dercynus, p. 502) 



Kostrum (seen in profile) about as long as the prothorax, curved, moderately stout, received in repose in the 

 very deep prosternal groove, which is closed behind by the raised horseshoe-shaped mesosternal process,

the scrobes short, deep, extending to the lower margin of the eyes, and inferiorly placed ; antennae 

 (fig, 24 b) inserted near the base of the rostrum, the scape clavate, slender at the base, not longer than 

 the first two joints of the funiculus united, joint 1 of the latter stout, 2-7 very slender, decreasing 

 in length, 2 as long as 1, 5-7 short and subequal, the club abrupt, comparatively stout, acuminate- 

 ovate, with distinct sutures ; eyes lateral, large, rounded, almost covered in repose by the ocular lobes 

 of the prothorax ; prothorax transverse, produced in front, deeply bisinuate at the base, the narrow 

 median lobe prominent; scutellum small, rounded, flattened; elytra elongate-subquadrate, conjointly 

 produced at the apex, and with the inflexed lower portion almost covering the metathoracic episterna, 

 which are very narrowly exposed posteriorly ; ventral segments 2-4 subequal in length ; legs short ; 

 femora stout, unidentate ; tibiae stout, compressed, rounded externally, almost straight on their inner 

 edge, armed with a sharp claw at the outer apical angle, the inner angle rectangular ; tarsi rather 

 slender, the third joint bilobed, pilose beneath, the claws long, slender, and divergent ; body elongate, 

 flattened above, nodose, densely clothed with flattened scales intermixed with very short, stout, blunt,

suberect setae. 

 Type, M. parallelus. 







The single species from Mexico from which the above characters are taken 

 belongs to the " Tylodides," and it is perhaps nearest related to Dercynus. Its chief 



characters are, the very slender funiculus (joint 1 excepted), the abrupt, acummate- 

 ovate antennal club, the flattened, rounded scutellum, the elongate, subquadrate 

 elytra, with the inflexed lower margins almost covering the episterna, the toothed 

 femora, and the long, slender, divergent tarsal claws. The general facies is that of 

 a small Nosoderma (Tenebrionidae), and the insect doubtless lives under the bark of 



trees-

1. Macracalles parallelus, sp. n. (Tab. IX. figg. 24, 24 a, b) 



Opaque, black, the antenna (the club excepted) and the tips of the tarsi ferruginous ; densely clothed with 

 brown adpressed scales, the elytra slightly variegated with darker brown, the short intermixed blunt 

 set* numerous on the legs and more scattered on the dorsal surface of the body. Head and rostrum 

 densely punctate, the latter with the long apical portion flattened, bare, and shining ; the joints of the 

 funiculus each with a few projecting bristly hairs. Prothorax abruptly narrowed beyond the middle, 

 the sides crenate, parallel at the base, the short, narrow, apical portion subcorneal; the surface densely 

 punctate and here and there nodose, the median basal lobe convex. Elytra a little wider than and 

 nearly two and one-half times as long as, the prothorax, subparallel in their basal half, the shoulders 

 rounded and somewhat prominent ; with rows of coarse scattered punctures, the interstices densely 

 punctate, uneven, more or less nodose (except along a broad flattened space down the basal half of the 

 suture), the third, fifth, and seventh subseriato-nodose, the third somewhat raised and with an oblong 



prominence at the base. 

 Length 4f , breadth 2| millim.
