48 MATERIALS TOWARDS A HISTORY 



black tuft at the base, a smaller one behind the middle, followed by another posterior one, these, with two corre- 

 sponding ones, forming a common quadrangle; a yellowish spot near the base and exterior margin; suture with a 

 row of small tufts; exterior margin spotted with yellowish; apex truncate: femora and under parts spotted with 

 brown, tibia; annulate. Colour and general appearance of the preceding variety. 



I have a small, imperfect specimen from Massachusetts, (Boston Collection, No. 53?,) 

 and another from Carolina, (ib. No. 1040,) which appear to be the same species, although 

 not more than 3i lines long. Another individual, 3 lines long, belongs to the collection 

 of Dr. Le Conte. 



130. A. INTERRUPTUS. 



Brown, punctured, prolhorax surrounded posteriorly with five tubercles, elytra truncate, with two costa?, 

 numerous glabrous, and four indistinct, cinereous spots. 34'" long; (elytra 21,) 1 j wide. Inhabits Pennsylvania. 



Cerambyx interruptus, Mels. Cat., No. 742. Front and antenna; spotted, the latter annulated with brown; 

 frontal line impressed throughout, a transverse line between the eyes and antenna;; margin of the labrum yellow, 

 palpi rufous: elytra reddish-brown, slightly hairy, with glabrous portions; an obsolete, cinereous spot at the base, 

 another at the outer margin behind the middle, a third posterior to this at the suture, and a fourth at the junction 

 of the costa: ; outer margin with a brown macula near the shoulder; epipleura cinereous, margined above and 

 below with a row of brown spots: feet and beneath cinereous hairy, spotted with brown; tibia; annulate. 



131. A. fascicularis, Harris. (Mesosa.) Tr. Nat. Hist. Soc, Hartford, i. 88. 



4 lines long. 



132. x\. sticticus, Dcjean. 8 mm. long; (elytra G,) 3 wide. 



This is probably a large variety (or perhaps the female,) of A. macula, Say, in which 

 the cinereous spot on the elytra extends to the suture. It appears to be noticed by Say, 

 when he describes the gray spot of the elytra as " rarely reaching the suture." 



133. A. macula, Say. (Lamia.) Journ. Acad. Nat. Sci., v. 268. Mels. Cat., No. 735. 

 A. hebes, Dej. Inhabits Pennsylvania, in June — August. 



134. A. alpha, Say. (Lamia.) Journ. Acad. N. Sc, v. 270. Mels. Cat., No. 738. Graph- 

 isurus pusillus, Kirby, N. Z., 169. Pennsylvania. A. cinereus, Dcj., appears to be a 

 small variety, with rather rougher elytra. 



Vak. A. divergem. Dull-brown, elytra with blackish velvety points, and a band behind the middle, running 

 backwards and outwards from the suture. 2 lines long. Inhabits Pennsylvania. 



Head convex, with a deep impression between the antenna 1 ; fifth, sixth, and seventh articulations of the antennae 

 pale-yellowish, and with the third and fourth tipped with black: pronotum with two diverging, velvety lines: elytra 

 minutely punctured, having blackish, velvety points, and an oblique band behind the middle, in front of which the 

 surface is slightly cinereous, with short hairs; inner extremity truncate; sternum and feet dull-brown, obscurely 

 cinereous; abdomen darker, polished. 



135. A. lateralis. 



Uniform reddish-brown, subglabrous; epipleura with a black band. G mm. long; (elytra 4s) 2 wide. In- 

 habits Pennsylvania. 



Front convex, covered with dull-grayish hair, deeply sulcate between the antennas; eyes black, prominent; 

 antennae with the articulations tipped with blackish: prolhorax finely punctured, and having a prominent lateral 

 tubercle, behind which il is suddenly reduced; an obsolete tubercle each side of the middle, anteriorly: elytra with 

 impressed punctures, sparsely hairy, with a black band along the epipleura from the base to beyond the middle; 

 apex truncate within: sternum slightly hairy.
