extremity; and the completion of the cavities is due to the greater prolongation 
forwards of the metasternal process. The gene are apparently immarginate. 
A single individual, unfortunately in bad preservation, is all J have seen; it presents 
no external mark indicative of sex. 
46. Homalota trisignata. (Tab. V. fig. 13.) 
Subopaca, subtilissime punctata et pubescens, variegata; antennarum basi, prothorace, elytrorum humeris, 
abdomine ex parte pedibusque testaceis ; capite, elytris ex parte, abdominis maculis et cingulo, pectoreque 
nigricantibus ; prothorace transverso, plus minusve discrete fusco-trisignato. 
Long. 3 millim. 
Hab. GuatrMata, Balheu in Vera Paz (Champion). 
Antenne of moderate length, distinctly thickened outwardly ; the four or five basal 
joints pale yellow, the others gradually a little darker; third joint about equal to 
second, fourth about as long as broad, seventh to tenth transverse ; terminal joint rather 
large, longer than the two following together. Head blackish, dull, sparingly and 
finely punctate. Thorax strongly transverse, nearly straight at the sides, slightly 
narrowed behind, closely and extremely finely punctate, with a longitudinal dark 
mark on the middle and a smaller mark on each side. Elytra longer than the thorax, 
black on the suture at the base, a very large black mark at the outer angle, and a band 
of yellow colour extending obliquely from the shoulder to the suture. Hind body yellow, 
with the basal segments marked with black in the middle and slightly spotted at the 
sides; the fifth segment entirely black, the apex of the last segment infuscate; the 
basal segments are sparingly punctate, the apical ones nearly impunctate. 
The four individuals vary a little in the extent and definition of the dark marks. 
The middle coxe are rather widely separated; the mesosternal process is of moderate 
length, not slender, with rounded extremity, separated from the moderately long meta- 
sternal process by a rather elongate intercoxal isthmus. The anterior tarsi are pretty 
certainly only four-jointed ; although under a moderate power of the compound micro- 
scope there is an appearance of the division of the fourth joint, yet I believe that, as in 
the case of Leptonia, this appearance will prove to be illusory. 
IT am not able to see well the seventh ventral segment; but in the male the dorsal 
plate of the sixth segment has an obscure elevated granule in the middle, near the hind 
margin, and I believe the hind margin of the following segment is quadridentate. 
47. Homalota cingulifera. 
Parum elongata, subopaca, subtiliter punctulata, nigro testaceoque variegata, antennis basi testaceis, extrorsum 
obscuris ; prothorace transverso, posterius angustato; abdomine segmentis 2°-5™ sat crebre punctatis.
