EUROPS. 571 
Closely allied to #. euplectoides, but rather longer and more depressed, and readily 
distinguished by the coarser thoracic sculpture. Head short, epistome convex, vertex 
coarsely punctate. ‘Thorax straight at the sides, the angles but little rounded, the 
lateral margin very fine ; rather coarsely punctate, with a smooth space on the middle, 
broad behind, narrower in front; this area is defined by punctures crowded so as to be 
almost confluent; there is no distinct depression behind. The strie of the elytra are 
very fine and regular. The coxal lines are detached, but are short, and very fine behind. 
One specimen, a female; the pygidium is elongate. 
Although we have received only the female of this species and the male of 
Li. euplectoides, I do not doubt that the two are distinct. 
12. Europs nanus, sp. n. 
Minutus, depressus, nitidus, testaceus ; capite parvo, subtiliter punctato; prothorace subquadrato, subtiliter 
punctato, medio area lata levigata; elytris subtiliter striatis, striarum punctis haud minutis. 
Long. vix 14 millim. 
Hab. GuateMaLa, Zapote (Champion). 
The smallest of the genus; much narrower than EL. euplectoides and more depressed, 
the surface more shining than in any other Ewrops known to me. The head is quite 
small, the antenne very short, but the ninth joint is strongly transverse. The thorax 
is straight-sided, the lateral margin very fine; the punctuation is fine and scanty, but 
surrounds a distinct, impunctate, median space, broad behind, narrower in front. The 
punctures of the elytra are larger than usual. The coxal lines are slightly detached, 
their terminal portions very fine and indistinct. One male. 
13. Europs longulus, sp.n. (Tab. XVIII. fig. 3.) 
Haud depressus, subcylindricus, ferrugineus, nitidus ; capite thoraceque elongatis, illo posterius tantum subcon- 
stricto, angulis posterioribus fere nullis ; prothorace sat crebre punctato, nullo modo impresso, medio area 
angusta, parum discreta, impunctata ; elytris punctato-striatis. 
Long. 3 millim. 
Hab. GUATEMALA, near the city (Champion). 
An aberrant species, with the facies of Rhizophagus, and distinguished by the 
transversely more convex form and the extremely indistinct hind angles of the head. 
Antenne with the ninth joint large, the club very distinctly biannulate. Head not 
flattened, sparingly punctured. Thorax almost parallel-sided, transversely convex, 
front angles not at all prominent, but nearly rectangular, hind angles very obtuse and 
rounded, punctuation very distinct but not at all dense. Llytra finely striate, the strie 
finely punctured. Coxal lines not at all detached; intercoxal process of abdomen 
narrow. ‘Two male specimens.
