Stelidota geminata, Er. in Germ. Zeitschr. iv. p. 802 >; Horn, Trans. Am. Ent. Soc. vii. p. 304°. 
Ovalis, sat lata, parum convexa, testaceo-ferruginea, plus minusve infuscata, elytris nigro-variegatis, apice 
nigro; prothorace lato, lateribus explanatis; elytris sulcatis, interstitiis equalibus. 
Long. 3 millim. 
Hab. Nortu America ! 23,—GvaATEMALA, near the city, Capetillo, Chiacam (Champion). 
The specimens from our region are broader, and have the elytra more variegate than 
the North-American examples I have seen. The axillary space is very small; the 
curvature of the hind tibiz of the male very large. richson also records? the species 
from the West Indies and South America, but this, I think, may not be correct. 
6. Stelidota ovalis, sp. ne (Tab. X. fig. 4.) 
Ovalis, minus convexa, nitida, ferruginea, plus minusve infuscata, elytris vage maculatis; prothorace late- 
ribus late explanatis, fere reflexis ; elytris evidenter seriatim punctatis, interstitiis ad basin vix elevatis. 
Long. 3} millim. 
Hab. Guatemauta, Calderas, Capetillo (Champion); Panama, Volcan de Chiriqui, 
Caldera (Champion). 
Thorax deeply emarginate in front, but little convex, deeply impressed near the sides, 
so that these are explanate and subreflexed ; base sinuate; hind angles slightly acute. 
Elytra elongate, shining, the serial punctuation and pubescence distinct, the latter 
unicolorous, the interstices at the base scarcely elevated. Axillary space small, but 
the coxal line abruptly reflexed and continued along the metasternum, as a fine line 
very close to the side-piece, for more than half the length of the breast. 
This species will be easily recognized by the peculiar coxal line; we appear not to 
have received a male. 
7. Stelidota stictica, sp. n. 
Ovalis, minus convexa, nigricans, elytris vage maculatis, antennis pedibusque fuscis, illarum basi, harum 
tarsis rufis ; prothorace marginibus reflexo-explanatis ; elytris seriatim longius pubescentibus, pubescentia 
variegata, interstitiis alternis subdepressis. 
Long. 3) millim. 
Hab. Guatemaa, Capetillo (Champion). 
Thorax deeply emarginate in front; base bisinuate ; sides largely explanate; surface 
not densely punctate. LElytra with the serial punctuation distinct, the series of hairs 
rather long and each variegate, dark hairs being succeeded by light hairs two or three 
times in each series, the alternate interstices evidently a little more elevated than the 
others. Axillary space small; coxal line abruptly reflexed, but continued for only a 
short distance backwards. 
We have received only two females of this species; it may be recognized by the
