cies; the maxille are not longer than the head; the mouth is very much pro- 
longed, and the last joint of the maxillary palpi longer than the preceding. 
20. N. porosa, testacea, vix pubescens, thorace subtransverso, lateribus 
rotundatis, parce grosse punctato, elytris confluenter punctatis, antennis nigris, 
tibiis tarsisque fuscis. Long. :24—-29. 
Two specimens, Georgia; in one of them the elytra are brownish, leaving 
only a narrow marginal suture and base testaceous. In structure and color 
resembles exactly the last species, but differs in the sparse punctuation of the 
thorax. 
21. N.fuscipennis, fusca, capite thoraceque testaceis, dense minus subtili- 
ter punctatis, hoc rotundato, elytris confluenter punctatis, antennis nigris, femori- 
bus plus minusve testaceis. Long. -i9—-27. 
St. Louis, Missouri, Dr. Engelman. ‘This species also, in the form of an- 
tenne, palpi, maxille and tibial spurs resembles the two preceding, but differs 
in the form of the thorax, which is nearly round ; the abdomen and thighs vary 
in color, being sometimes testaceaus and sometimes fuscous. 
The following species are unknown to me:

23. N. calceolata Guerin, Icon. Régne An. 136. ‘Reddish, finely granu- 
late, antenne, eyes, palpi, tip of mandibles, maxille, base of femora, tibia and 
tarsi black. Long. 10 mill.; lat. 34 mill.”? This may probably be allied to N. 
lurida Lec., but as no essential character is expressed in the description, it is 
impossible to recognise the species. 
24. Gnathium Francilloni Kirby, Linn. Tr. 12, 424, tab. 22, fig. 6. 
The genus is said to have the mandibles elongated, and the antenne thickened ex- 
ternally; the first character is possessed by all the species of Nemognatha in 
(B—e); the second character I have not observed in any species.

1. Z. atripennis, lete flavo-testacea nitida, thorace non transverso, late- 
ribus antice rotundatis, minus dense punctato, elytris nigris brevissime pubes-

Missouri Territory and Santa Fe. The mouth is more prolonged than in the 
other species, but the maxille are destitute of the thread-like extension found in 
Nemognatha. The second joint of the antennz is equal to the first, and shorter 
than the third. The spurs of the posterior tibie are slender, the outer one a 
little longer and obtuse. 
2. Z. flavida, flava, nitida, thorace non transverso, lateribus antice rotun- 
dato, minus dense punctato, elytris brevissime pubescentibus parcius grosse 
punctatis, tibiarum apice, genubus tarsisque fuscis, antennis nigris. Long. -4. 
Santa Fe, New Mexico. Mr. Fendler. In form and sculpture resembles the 
preceding. One specimen has a large black blotch at the apex of the elytra. It 
is possible that a larger series of specimens may prove the necessity of uniting 
this with the preceding species. 
3. Z. bilineata, testacea, thorace subtransverso, quadrato, angulis rotun- 
datis, parce punctato, elytris rngose punctatis, pallidis, vitta utrinque fusca, sepe 
obsoleta, pectore, tibiis, scutelloque plus minusve infuscatis, antennis nigris.

Middle and Western States, rare. I procured a fine series of this species at 
Fort Snelling, Minnesota. The elytral vitta is slightly abbreviated at base. and
