ZONITIS. | 385 
This species is not closely allied to any other here described. It may be readily 
known by its long and narrow head, campanulate, sanguineous thorax, and depressed, 
broad, dull black, granulated elytra. The head, scutellum, and under surface vary in 
colour. In some of the specimens with the head flavous, the head itself is longer, 
narrower, and more parallel than usual. The second joint of the antenne varies in 
length, it being considerably shorter than the third in some specimens. The thorax 
often has the punctures confluent, and when this is the case the surface is opaque, not 
shining. The different varieties are connected by intermediate forms. 
This insect agrees in some respects with Dugés’s description of Z. flavicollis; the 
colour of the thorax, however, is not yellow, but pale sanguineous; and the head is 
narrow and subparallel, not broadly triangular. We figure two specimens, one from 
Duenas and one from Chontales. 
7. Zonitis lateritia, (Tab. XVII. fig. 22.) 
Elongate, finely pubescent, above and beneath reddish-testaceous, opaque; the eyes, the tips of the mandibles, 
the palpi, antenne, tibie, and tarsi black. Head comparatively small, narrow, prolonged in front, with 
the labrum rather longer than broad and the mandibles elongate, closely and finely punctured ; the eyes 
transverse, rather small; antenuz setaceous, very long and slender, joint 1 stout, 2 and 3 more slender, 
equal, 4-11 decreasing in thickness, 4-7 almost equal in length, very much longer than 3, 8-11 very 
slender, 11 a little longer than 10; prothorax much wider than the head, rather longer than broad, sub- 
campanulate, considerably narrowed in front, subparallel at the sides behind, depressed on either side of 
the middle anteriorly, closely and finely punctured, with a well-marked smooth median line (raised before 
the middle and depressed behind) ; scutellum densely, minutely punctured; elytra elongate, widening a 
little posteriorly, very densely and finely punctured ; beneath more sparsely punctured, shining; hind 
tibial spurs stout, spoon-shaped, subequal. 
Length 13 millim.

. 
One example. The small, narrow, anteriorly prolonged head, small eyes, uniform 
reddish-testaceous body, and black antenne distinguish this species at a glance from 
Z. megalops. 
8. Zonitis nigromaculata. (Tab. XVII. figg. 23; 23 a, maxillaand maxillary 
palpus. ) 
Zonitis nigromaculata, Dugés, An. Mus. Michoacano, ii. p. 111 dis’. 
Hab. Mexico, Atoyac (Flohr 1), Tuxtla (Sallé). 
We have received four examples of this very distinct species, two from Atoyac and 
two from Tuxtla. It closely resembles Nemognatha ephippiata, but is more elongate 
and has a longer and narrower head, and very differently formed antenne. The head 
and thorax have a black vitta on either side ; tbe elytra have a very broad fascia below 
the base, extending broadly upwards along the suture to the base, and the apical third 
black ; the rest of the upper surface is tawny-yellow. ‘The antenne have their five
