EULIMNICHUS. 675 
4, Kulimnichus optatus, sp. n. 
Ovalis, niger, fere subenescens, nitidus, parce punctatus, subtiliter pubescens ; prothoracis angulis ante1ioribus 
brevissime spinosis, 
Long. vix 2 millim. 
Hab. Mexico, Cuernavaca (Mohr), Tupataro (Hoge); Guatemala, near the city, | 
San Gerdénimo (Champion). 
Closely allied to E. leticulus, but slightly less elongate, and with the surface more 
polished; besides this, the front angles of the thorax are certainly, though most 
minutely, spinose. 4. optatus is also very similar to a New Mexican species sent me 
by Mr. Wickham, and which I believe to be £. perpolitus, Casey. ‘Ten specimens: 
the two from Guatemala do not quite agree with the types, which were sent me by 
Mr. Flohr; those from Tupataro are also a variety. 
5. Kulimnichus plebeius, sp. n. 
Ovalis, sat latus, niger, breviter squamosus, minus variegatus, antennis rufis; subtiliter punctatus, haud 
nitidus, punctatura basin versus obsoleta, apicem versus discreta; prothoracis angulis anterioribus 
haud spinosis. 
Long. 2-24 millim. 
Hab. Mexico, Cuernavaca (Mohr); Guatemata (Sallé), San Gerénimo (Champion). 
One of the most commonplace and unattractive species; slightly larger than 
Limnichus versicolor, Waltl, which it superficially much resembles. The antenne are 
quite short, the two or three penultimate joints distinctly transverse; they are dull 
reddish or black in colour. The sides of the thorax are less depressed than usual, 
standing out a littlemore. The scutellum is elongate. The punctuation of the elytra 
behind is dense and fine, at the base more effaced. The clothing consists of short scale- 
like depressed hairs, chiefly of a flavescent colour, and indefinitely variegated with white. 
Viewed from beneath, the prothoracic anterior angles are seen to be very obtuse, 
though just perceptibly free. The prosternal groove is broad, but not very deep; and 
the mesosternum is slightly sulcate, so that there is in some lights an appearance of 
the channel extending from near the front of the prosternum to near the apex of the 
metasternum. ‘The abdominal punctuation is extremely fine. There is an indistinct 
transverse channel on the coxal plates of the hind legs. ‘Ten specimens.

Limnichus (Eulimnichus) analis, Casey, Ann. N. York Acad. v. p. 148°. 
Hab. Nortu America, Texas, Arizona2, California !?.—Mexico, Yautepec (Flohr), 
Teapa (H. H. Smith); Panama, Tolé (Champion). 
The four specimens I refer to this species come from three localities, and are far 
from agreeing among themselves; but they approach so closely to an example of
