OTHNIUS. 467 
Antenne moderately long, at least reaching to the base of the prothorax. 
Head and prothorax very closely and coarsely punctured. 
Antenne with joints 9 and 10 transverse; elytra with numerous 
fusco-testaceous spots and angular markings . . . . . . multiguttatus. 
Antenne with joints 9 and 10 as long as broad; elytra with 
markings more indistinct, and in the form of narrow zigzag 
fascie 2... ee ee ee ee ee tintricatus. 
Head and prothorax sparsely and coarsely punctured. 
Elytra with a broad angulated band behind the middle, a small 
spot on either side of the suture before the apex, and some 
other markings towards the base, testaceous. . . . . . . mewicanus. 
Elytra with a broad angulated band before the middle, another 
(but narrower) one behind the middle, and the apex, testaceous _ sticticopterus. 
1. Othnius senecionis. (Tab. XXI. fig. 14.) 
Blackish-brown, opaque, the elytra slightly shining, the head and prothorax densely clothed with short appressed 
hairs, the elytra with longer and more scattered decumbent ashy hairs. Head very densely and rugosely 
punctured, the intraocular space convexly raised in the middle, the eyes moderately large; antenne 
very short, not reaching the base of the prothorax, joints 9 and 10 strongly transverse, ferruginous, 
the last three joints a little darker; prothorax very convex, the sides much rounded, about equally 
narrowing before and behind, and shallowly emarginate behind the middle, the emargination preceded 
and followed by a short tooth, the hind angles rather acute, the surface very densely and rugosely 
punctured throughout, velvety-blackish-brown, with a longitudinal stripe on the middle of the disc 
white ; elytra long and convex, subparallel, dark bronze with an irregular network of testaceous markings, 
densely and not very finely punctured, the punctures coarser towards the base ; legs ferruginous. 
Length 53-53 millim. (¢ @.) 
Hab. Mexico, near the city (Flohr). 
Two examples. This very distinct new species has been kindly forwarded to me by 
My. Flohr, who states that he found it in withered stems of Senecio. O. senecionis is 
.. «more convex than any of the other species enumerated here, from which its very short 
antenn, rugose and opaque head and thorax, intricate elytral pattern, and other 
characters mentioned above abundantly distinguish it. ‘The intricate elytral markings. 
will be best understood from our figure. 
9. Othnius antennalis. (Tab. XXI. figg. 15; 15, a, antenna.) 
Dark bronze, shining, sparsely clothed with short ashy decumbent hairs. Head closely and coarsely punctured ; 
antennse testaceous, short, about reaching to the base of the prothorax, joints 9 and 10 very strongly 
transverse, 9 obliquely produced on its inner side; prothorax moderately transverse, coarsely and closely 
punctured, the punctures more scattered on the anterior half of the disc, the disc with a narrow ill-defined 
longitudinal space in the middle impunctate, the sides feebly emarginate before and behind the middle, and 
with a short tooth before and behind the emarginations, the hind angles rather obtuse; elytra subparallel, 
rather finely and somewhat thickly punctured, the punctures coarser towards the base, marked thus :— 
an oblique stripe extending from the shoulders nearly to the suture (separated from a triangular scutellar 
patch by an oblique stripe of the ground-colour), a common sutural patch about the middle, a zigzag band
