NAUPACTOPSIS. 279 
in having the prothorax more closely foveato-punctate in both sexes; the elytra 
irregularly striate towards the sides anteriorly, relatively shorter and more narrowly 
acuminate at the apex in the female, and with subangular humeri in the male. The 
markings, which are easily abraded, are somewhat different from those of NV. auropictus, 
the prothoracic vitte being placed further inwards and the streak on the elytra 
duplicated towards the base ; the striz, too, are more irregular on the disc. 
2. Naupactopsis auropictus, sp.n. (Tab. XIII. figg. 1, 3; 2, 2.) 
Elongate, rather convex, narrow, and subelliptic (¢), broad and subpyriform ( @ ), black or piceous, the legs 
varying in colour from black to ferruginous; clothed with minute brown, cinereous, or coppery scales, 
the prothorax with a narrow stripe on each side of larger, imbricate, whitish, green, cupreous, or golden 
scales which is often interruptedly continued down the dise of each elytron, the flanks of the latter 
and the larger punctures of the upper surface frequently bearing similar metallic scales ; the surface also 
set with small, decumbent, scattered pallid sete. Head and rostrum densely, finely punctate, the 
rostrum slightly longer than broad, feebly or obsoletely carinate down the middle, the nasal plate short, 
the inter-ocular fovea small; antennal scape reaching beyond the eyes, the latter large and depressed. 
Prothorax about as long as broad, rounded at the sides, in the ¢ scarcely narrower at the apex than 
at the base, in the 2 broader behind and subtransverse, truncate at the base, narrowly suleate down 
the middle; impressed with scattered irregular foveiform punctures intermixed with a fine dense 
interstitial punctuation. Scutellum small, LElytra oblong-oval in ¢, broader, widened to the middle, 
and more abruptly acuminate in @, the bumeri obtuse, the apices feebly mucronate, the dise usually 
with two or three scattered shallow irregular depressions ; coarsely punctate-striate, the strice regular at 
the base, the interstices densely punctulate, narrow and uneven in 4, broad and sometimes flat in 2. 
Var.? The prothorax with a broad submarginal vitta, which is continued down the disc of the elytra to the 
apex, and a broad stripe along the lower margin of the latter, densely clothed with greenish ( ¢) or 
golden-cupreous ( 2 ) scales; the legs in great part ferruginous. 
Length 93-15, breadth 3-6} millim. (¢ 2.)

coalco, Parada, Jacale (Sallé), Omilteme in Guerrero (#7. LH. Smith). 
A very variable insect, and the sexes dissimilar im form. The seriate punctures on 
the elytra are larger, scattered, and foveiform in the more rugose examples, and often 
bear a few metallic scales, like those on the submarginal vitte of the prothorax. The 
penis-sheath of the male is broad, somewhat pointed at the tip. The second joint of 
the funiculus is somewhat elongated in the female. A long series of both sexes has 
been sent us by Hége. The variety ? is represented by a pair obtained from M. Donckier 
labelled ‘* Mexico.” 
3. Naupactopsis sitonoides, sp.n. (Tab. XIII. fig. 3, 2.) 
Oblong-oval, moderately convex, dull, nigro-piceous; densely clothed with small coppery-brown scales, with 
whitish scales intermixed, these latter becoming more numerous on the head, along the sides of the 
prothorax, and on the humeri and sides of the elytra, the surface also set with short, curled, scattered 
hairs. Head and rostrum densely, rugulosely punctate, the rostrum about as broad as long and obsoletely 
carinate to the small inter-ocular fovea; antenne comparatively short, the scape barely reaching the 
posterior margin of the eyes, the latter widely separated and not prominent. Prothorax broader than 
long, rounded at the sides, narrowed in front, and truncate at the base; rather coarsely, closely punctate, 
and with a fine, dense, interstitial punctuation, Scutcllum small. Elytra somewhat convex, much
