2. Acysta interrupta, n. sp. (Tab. III. fig. 23.) 
Moderately long, black; the pronotum with the anterior and the interrupted lateral margins, the median 
carina in front, and the triangular posterior portion whitish or pale testaceous ; the elytra with a trans- 
verse fascia below the base, extending to the subcostal and discoidal areas, the apex, and sutural area 
fuscous, the rest of the costal area pale testaceous or whitish, with the areole hyaline, the raised longi- 
tudinal nervures testaceous ; the spines on the head, the antenna, and legs flavous. Antenne moderately 
long, joint 3 barely twice as long as 4. Pronotum closely punctured and tricarinate, strongly constricted 
in front, with a small ear-like membranous expansion on each side behind, the anterior portion parallel 
and with a short narrow membranous margin. Elytra oblong-oval; discoidal area extending to a little 
beyond the basal third; costal area with three or four rows of areole. 
Length 23, breadth 1-13 millim.

Lwo examples. This is the only Central-American Tingitid known as yet with the

A common insect from Guatemala southwards, occurring on both the Atlantic and 
Pacific slopes. St&l’s type has been examined. In this, as in the following species, 
the intercoxal portion of the metasternum is transversely cordate, and the rostral 
channel rather wide and subparallel on the mesosternum, the rostrum reaching the 
meso-metasternal suture. The wings are nearly as long as. the elytra. The North- 
American WM. labeculata, Uhler, is probably an allied form. A specimen of Jf. mono- 
tropidia from Chacoj is figured. 
2. Monanthia c-nigrum, n. sp. (Tab. III. fig. 25.) 
Finely pubescent, black, the elytra and the disc of the pronotum obscure ferruginous, the membranous 
margins of the pronotum ochraceous, the elytra with the posterior portion of the nervure closing the 
discoidal area black (forming a C-shaped mark) and the nervures of the sutural area in great part also 
black, the areole of the costal area hyaline; the antenne with joint 3 testaceous and the other joints 
black ; the femora and tarsi black, the tibiee testaceous. Head with three short frontal spines; antenne 
rather short, joints 1 and 2 equal, 4 about as long as 1 and 2 united. Pronotum with the opaque mem- 
branous margins extending rather broadly inwards, in some specimens occupying about two-fifths of the 
entire width; the disc closely punctured and tricarinate, the outer carine short. Elytra oval; the 
discoidal and subcostal areas closely punctured, the discoidal area extending to the middle, the nervures
