i(j*) APPENDIX. 



smootli and shining, indistinctly depressed transversely behind 

 the middle ; whole surface remotely covered \nth large deep siib- 

 ovate punctures. Scutellum smooth, minutely punctiu'ed. Elytra 

 broader than the thorax ; sides margined, nearly parallel ; a^ex 

 rounded, conjointly emarginatc at the sutiu'e, apical margin 

 minutely serrulate ; above subconvex, slightly flattened along the 

 suture, smooth and shining, each el}'tron impi'essed with eleven 

 rows of lai'ge deep punctiu'es, Avhich cover nearly the whole siu'- 

 faee of the elytron (the first abbreviated) ; the punctm-es on the 

 striae placed near the posterior four-fifths of the suture smaller 

 and less deeply impressed ; interstices towards the sides and apex 

 elevated, subcostate ; lateral margin slightly reflexed, coarsely and 

 transversely strigose. Beneath sliining black ; head and thorax 

 rufous ; apical segment of abdomen broadly truncate-cmarginate, 

 its middle portion sinuate (Tab. III. fig. 42). (Male.) 



Uah. San Andi-es Tuxtla. 



Unique in the collection of M. Salle. 



Eemarkable for the coai'se punctation of the elytra : it ought to be 

 placed close to C. nigricornis, to which species it is nearly aUied. 



Page 48. — Cephaloleia Waterhousei. 



On closer examination, I find that I have erred in describing the 

 apical segment of the 5 of this species as being armed with an 

 obtuse tooth ; the segment is broadly emarginate, and has the central 

 l)ortion slightly produced.

C. late clongata, dorso subdepressa, supra nigra, nitida ; antennis 

 (articulis duobus basaHbus exceptis) obscure fulvis ; el}i;ris flavis, 

 piuicto humeraU maculaque communi postice, nigro-piceis ; subtus 

 nigro-picca ; pedibus abdomineqiie ful^is, hoc piceo. 



Ftem. Abdominis scgmento anali late truncato-emarginato. 



Long. 21 lin. 



C. broadly elongate, subdepressed along the back, shining black 

 above ; antenna3 (the two basal joints excepted) obscure fulvous ; 

 elytra shining yellow, a small spot on the humeral caUus, and a 

 larger common siibovate patch immediately behind the middle, 

 nigro-piceous ; beneath nigro-piceous, legs and abdomen fiilvous, 

 the latter stained with piceous. Head concave between the eyes, 

 deeply punctured ; antennae moderately robust, filiform, fii'st joint 

 scarcely incrassate, shghtly longer than the second. Thorax 

 transversc-quadi-ate ; sides narrowly margined, straight and par- 

 allel, narrowed and rounded at theii- extreme apex, slightly pro- 

 duced beyond the apical margin, the latter straight ; abo^'c 

 ti-ans\ersely convex, sm-face covered ^-ith large round punctures.
