scribed by Mr. Spinola in liis beautiful monograpli of Cleridse. It is however, 
much to be regretted that his descriptions are drawn up in such a manner as 
to render it extremely difficult to recognize the species ; the present does not 
agree with any of the figures in his work. 
Trichodes Herbst. 
T. tenellus, elongatus, cyaneus, pilis albis erectis pilosus, capite thorace- 
qne punctulatis, elytris linearibus, annulo humerali ramum suturalem dilatatum 
postice emittente, fascia ad medium introrsum oblique descendente, alteraque 
postica, ascendente flavis, grossius subseriatim punctatis. Long. '22 — ••27. 
Fort Yuma, California, At first sight this might be considered a variety of 
T. ornatus, but the smaller size, the more slender form and the much 
coarser and more regular punctuation of the elytra induce me to regard it as 
distinct. The markings are as in that species, except that the middle band of 
the elytra is more oblique : no variety in the markings was observed. 
Clerus Geofl'r. 
C. aff Hiatus, obscure rufus, albo-pubescens, thorace dense punctulato, 
latitudine hand breviore, antrorsum angulatim impresso, elytris densissime 
punctatis, versus basin fere scabris, fascia alba lata ad medium nigro-margi- 
nata ad suturam anguste interrupta, alteraque postica angusta cinereo-pubes- 
cente ad apicem nigricantibus ; pedibus antennisque nigris, his ad basin rufis. 
Long. -38— -5. 
Texas, at Eagle Pass and Ringgold Barracks, Mr. Schott. Resembles in color 
C. 4-signatus, but the elytra are much more densely punctured and with- 
out lustre. The posterior band is only a little paler than the ground color, 
and is only rendered obvious by the cinereous hair with which it is clotted : 
the space between the fasciae is partly dark rufous, while in C. 4-signatus it is 
entirely black. 
C. latecinctus, rufus albo-pubescens, thorace subtiliter punctate, latitu- 
dine paulo breviore, antice angulatim impresso, elytris confertim gequaliter 
minus subtiliter punctatis, fascia lata media pallida ornatis, apice pallidiore 
late cinereo-pubescente, apice summo infuscato, spatio intermedio plus mi- 
nusve rufo-tincto. Long. '3 — '38. 
Colorado River and Sonora. Resembles somewhat C. ichneumoneus , 
but the thorax is not so convex, and the other characters are also different. 
Even in the darkest specimens the feet are rufous, but in one the abdomen is 
marked with two rows of black spots. 
C. abruptus, brevier rufus, cinereo-pubescens, thorace confertissime 
punctulato, latitudine hand longiore, antrorsum angulatim impresso, elytris 
convexis, confertim postice subtilius punctulatis, nigris macula basali, fascia 
lata paulo lunata Integra ad medium albidis, apice late cinereo-pubescente, 
postpectore abdomineque nigris, pedibus rufis. Long. -3. 
One specimen found at Eagle Pass by Mr. Schott. Must be placed near C. 
4-signatus, though very different from that as from every other species 
known to me. 
DoRCATOMA Herbst. 
D. grave, ovale convexum, antice obtuse acuminatum, fusco-testacum 
dense subhelvo-pubescens, subtilissime punctulatum, elytris parce punctatis, 
striis externis duabus postice profundis antice obliteratis ; antennis flavis, 
articulo Imo testaceo, ultimis tribus latitudine longioribus. Long. -11 — -14. 
Middle and Southern States, as far as Texas. I have adopted a manuscript 
name proposed hy Dr. Melsheimer. 
D. pusillum, rotundato-ovale, convexum antice obtuse acuminatum, 
fusco-testaceum dense helvo-pubescens, subtilissime punctulatum, elytris 
parce punctatis, striis externis duabus pone medium impressis, antice oblite-
