TINOTUS.—PHILOTERMES. 171 
elsewhere. Elytra slightly longer than the thorax, obscurely rufescent towards the 
suture, finely punctate, hind margin slightly sinuate at the outer angle. Hind body 
convex beneath, densely and evenly punctate, dull, the hind part of the sixth segment 
and the seventh reddish. 
Three individuals of this species have been found; they are probably all males, and 
are remarkable in that the ventral plate of the seventh segment of the hind body is 
prolonged, and that its broad straight hind margin is densely set with coarse, flat, 
semi-membranaceous cilia; this plate is smooth and shining. It is possible that the 
remarkable thoracic depression may prove to be peculiar to this sex. 
2. Tinotus flavescens. 
Haud depressus, sat crebre punctatus, brevissime pubescens, subnitidus, flavo-ferrugineus, antennis, basi 
excepta, fuscis; prothorace fortiter transverso, transversim valde convexo. 
Long. 24 millim. 
Hab. GUATEMALA, near the city (Champion). 
Antenne short and stout, thickened externally; joints five to ten transverse, the 
last of them strongly so; terminal joint as long as the two preceding together. LElytra 
short, as long as the thorax, sparingly punctate. Hind body closely punctate, the 
punctuation of a peculiar strigose nature. 
Only one individual has been found. Although possessing quite the same facies as 
T. cavicollis, the species appears to be undoubtedly distinct. Possibly the specimen is 
a female; at any rate it possesses neither the peculiar ventral structure nor the thoracic 
impression of 7. cavicollis. 
PHILOTERMES. 
Philotermes, Kraatz, Linn. Ent. xi. p. 18 (1857). 
This genus consists of three North-American species, which inhabit the nests of 
Termites; and to these insects I believe I am correct in adding a fourth species from 
Guatemala, although, as I have never seen any of the North-American species, and as 
Kraatz has based the genus almost solely on a description of the trophi, this 1s somewhat 
doubtful—as is also the location of the genus in the Myrmedoniina, the number of 
joints of the intermediate tarsus not having been observed or recorded. 
1. Philotermes laxicornis. (Tab. V. fig. 7.) 
Testaceus, elytris obscurioribus, parce pubescens, elytris abdomineque obsolete punctatis; thorace sublevigato, 
latiore quam elytra, lateribus rotundatis. 
Long. 23 millim. 
Hab. Guatemaua, Las Mercedes 3000 feet (Champion). 
Antenne not elongate nor stout, evidently thickened externally, third joint shorter 
and considerably more slender than the second; fourth joint elongate, a good deal 
longer than broad, shorter than the third; fifth quite as long as broad, tenth a good
