190 STAPHYLINIDA. 
shorter than second, fourth subquadrate; fifth to tenth transverse, the last of them 
strongly so; terminal joint rather large. Head small. Prothorax strongly transverse, 
finely and rather closely punctate and pubescent. Elytra longer than the thorax, 
rather more distinctly and less closely punctate. Hind body concolorous with the 
anterior parts, the fifth and sixth segments slightly darker ; it is indistinctly punctate, 
the apical segments more sparingly than the basal ones. Legs rather short. 
This is an Oxypoda-like insect, differing in colour and appearance from any of our 
European Homalotew. Only two individuals, in very fragile condition, have been found ; 
and I have not succeeded in getting a clear sight of the sternal structure; but it appears 
to me that the middle coxe are very nearly contiguous, but are separated by a very 
slender and elongate process of the mesosternum. | 
38. Homalota annulata. 
Minuta, testacea, capite abdominisque segmento quinto nigricantibus ; antennis fuscis, basi testacea, brevibus, 
erassiusculis, articulis 5°-10™ fortiter transversis; prothorace convexo, fortiter transverso, subtilissime 
punctato; abdomine apicem versus attenuato, basi crebre, apice sparsim punctato. 
Long. 2 millim. 
Hab. GuaTEMALA, Guatemala city (Champion). 
Antenne short and stout, a good deal thickened externally, the three basal joints testa- 
ceous, the others infuscate ; third joint much shorter than second ; fourth to tenth similar 
to one another in length, but each broader than its predecessor, the first of them slightly, 
the last of them strongly transverse ; terminal joint rather large. Head small, blackish. 
Thorax very convex and strongly transverse, much rounded at the base, distinctly 
narrowed in front, bright yellow, very finely punctulate. Llytra slightly longer than 
the thorax, closely and finely punctate, of a yellow colour, a little infuscate at the 
base, especially near the scutellum. Hind body pointed behind, rather strongly setose 
about the apex, of a yellow colour, with the fifth segment nearly black, the four basal 
segments rather closely punctate, the following more sparingly. Legs clear yellow. 
In this species the middle coxee apparently quite touch one another about the middle 
of their length. Although similar in style of colour and appearance to H. leticula, it 
is very doubtful whether the two will prove to be really closely allied. Only two 
specimens of H. annulata have been found. | 
39. Homalota longipennis. 
Scutello occulto, elytris elongatis; fusca, antennis basi, pedibus (sepiusque ano) testaceis; parce punctata, 
tenuissime pubescens; antennis apicem versus crassioribus, articulis penultimis transversis. 
Long. 2 millim. 
Hab. Mzxico, Guanajuato (Sallé). 
Antenne not elongate, a good deal thickened externally ; the four or five basal joints 
yellow, the others obscure. Head small, narrowed behind the eyes. Thorax very
