but clearly defined, dorsal 1-4 and sutural complete, sutural 
joining the fourth at the base, 5 shortened before the base, 
4—5 and sutural are finely crenulate; the propygidium and 
pygidium are somewhat sparsely punctulate; the prosternum, 
strie extremely fine and only traceable before the cox, but 
there is a short marginal stria, also extremely fine at the base 
opposite the coxe, the mesosternal stria is complete and also 
fine, but not so fine as the prosternal striw, the transverse 
stria is crenulate ; the metasternum has a few large shallow 
punctures at its base, especially in the area near the median 
coxe; the anterior tibiz are multispinose on the anterior edge, 
a characteristic of all the species of the genus.

Tylois mirificus, sp. n. 
Breyiter ovalis, niger, nitidus; fronte rugose punctata; pronoto 
angulis anticis rufis, basi utrinque profunde excavata, parte ante- 
riore punctata; elytris striis punctiformibus, tenuiter impressis. 
L. 3 mill. 
Shortly oval, gibbous in the region of the elytra, black and 
shining; the head rugosely punctured, lateral margins carinate, 
clypeus truncate anteriorly, constricted behind, labrum short, 
transverse and smooth ; the thorax, anterior angles prominent, 
obtuse, and reddish brown, anterior area conspicuously and 
rather closely punctate, impressed behind the anterior angles, 
feebly carinate behind the middle of the neck, posterior area 
is nearly smooth in front of the scutellum, and on each side 
opposite the middle of each elytron is a deep lobe-shaped 
excavation, and on the outer side of each excavation is a 
narrow comma-shaped sulcus; the elytra are bordered with 
a lateral carina which represents the inner humeral stria, the 
carina is very strong at the base, and outside of it close to the 
base is a short strong carina which apparently represents the 
humeral oblique stria, behind the region of the thoracic exca- 
vations there are on each elytron close to the base three 
short elevated ridges, the six dorsal striz are almost obsolete, 
being merely indistinctly represented by lines of fine punc- 
tures, the sutural striais the most complete ; the propygidium 
and py gidium are somewhat opaque and obscurely and sparsely 
punctulate; the presternum is tuberculate anteriorly, bi- 
striate, strie divergent before and behind, keel smooth; the 
mesosternum is 3-tuberculate and densely punctate ; the first 
segment of the abdomen is punctate, but smooth in the middle ; 
the anterior tibia are 4—5-dentate, the median and hind 
tibie are angulated in the middle.
