236 STAPHYLINIDA. 
This appears to be a common species. Mr. Flohr’s specimens were found in garden- 
refuse; the colour is subject to considerable variation. It has quite the facies of the 
European F. thoracica and Ff. sulcata ; but the structure of the mesosternum really calls 
for its generic separation; the hind margin of this part presents itself as a free raised 
edge, and is not produced backwards between the middle coxe; the middle coxal 
cavities have no definite border internally, and are rather widely separated. 
2. Chitalia granigera. (Tab. VI. fig. 8.) 
Fusco-rufa, capite thoraceque fere subanescentibus, parum dense sed distincte pubescens, nitida ; antennis 
crassiusculis, fuscis; prothorace subcordato, basi abrupte fortiterque constricta, dorso canaliculato cre- 
breque granuloso-punctato ; scutello canaliculato; elytris quam thorax longioribus, perparum punctatis, 
tenuiter pubescentibus ; abdominis segmentis 1°-3™ basi fortiter sculpturata ; pedibus testaceis. 
Long. 4 millim. 
Hab. Guaremaa, Guatemala city, Capetillo, Aceituno, Coatepeque 1300 feet, Senahu, 
El Tumbador 2500 feet (Champion) ; Panama, Bugaba 800 to 1500 feet (Champion). 
This species is remarkable by the granulose punctuation on the middle of the thorax ; 
the thoracic channel is not so largely developed as it is in C. crenata, but is deeper and 
broader in certain specimens, which are probably males; the sculpture on the basal 
abdominal segments is largely developed, and is accompanied by minute elevated 
granules behind the large crenulations ; even the fourth segment is crenulate at the 
base. 
It is closely allied to a North-American species (probably Falagria bilobata, Lec. & 
Say), but has the antennz less elongate; the more northern species has the thorax 
more gradually narrowed behind, and the basal portion of the wing-cases rather closely 
punctate. 
3. Chitalia debilis. 
Fusca, parum nitida, crebre subtiliter punctulata et pubescens, pedibus testaceis; antennis crassiusculis ; 
prothorace subcordato, dorso convexo, simpliciter canaliculato ; scutello canaliculato; elytris quam thorax 
paulo longioribus, subtilissime sat crebre punctulatis; abdominis segmentis 1°-3” basi sculpturatis. 
Long. 3 millim. 
Hab. Guaremata, Rio Naranjo 450 feet (Champion); Panama, Bugaba 800 to 1500 
feet (Champion). 
This species appears to be very closely allied to C. dubia, but is of narrower form 
and more obscure colour, the prothorax and basal abdominal segments not being 
rufescent ; the sculpture at the base of the first three abdominal segments is finer ; and 
the prothorax is more gradually narrowed behind, and along the middle has a simple 
channel, not a broad impression. 
A single individual from each of the two localities is all I have seen.
