PROCEEDINGS OP THE ACADEMY OF 
Paeia Lec. 
P. quadriguttata, supra pallide testacea nitida, capite parce punctate, 
thorace convexo parce punctate, lateribus rotundatis angulis posticis haud 
rotundatis, margine basali apicalique infuscatis, elytris tliorace latioribus con- 
vexis, fortiter striatim punctatis punctis postice parvis, macula utrinque sub- 
basali, alterisque duabus linearibus confluentibus ad medium ornatis ; subtus 
picea, abdominis margine pedibusque pallide testaceis, antennis testaceis ad 
apicem infuscatis. Long. -17. 
Fort Yuma, California. Closely resembles Colaspis 6-notata Say, but is 
more slender, with tbe tborax less punctured, and the under surface darker. 
The genus Paria is established for the present species, Col. 4-notata Sm/.. 
6-notata Sat/, aterrima Oliv,, and canellus Fabr., with several nondescripts. The 
species mentioned, which were known to Dejean, were placed by him at the end 
of the genus Metachroma, with the first mentioned species of which they have 
no affinity, except that resulting from form. They are to be distinguished asi 
follows : 
Body glabrous, head not sculptured, antennae distant, slender, second jomt 
thicker, but shorter than the third ; thorax margined, angles not auriculatecl, 
beneath broadly lobed behind the eyes, presternum deflected and hollowed so 
as to protect tlie mouth when the head is bent down. Femora not toothed 
posterior tibife externally broadly emarginate near the tip ; ungues bifid. 
Myochrotjs (|Chevr.) 
M. 1 o n gu 1 u s , elongatus nigro-piceus, dense punctatus, squamulis xneo- 
fuscis densissime tectus, thorace latitudine longiore, lateribus subparallelis 
fortiter tridentatis, antice oblique truncatis, angulis omnibus prominulis. Long. 
•2. 
Fort Yuma, California. Different from our other species by the form of the 
thorax, and the more elongate body. 
Haltica Fabr. 
H. fumata, ovalis supra flava, ore occipiteque fiiscis, thorace Isevi, latitu- 
dine duple breviere, lateribus obliquis subrectis, macula media antice latiore 
nigra, alteraque utrinque obliqua fusca ; elytris subtilissime parce punctulatis, 
sutura vitta disceidali alteraque submarginali nigris ; corpore subtus, pedibus 
antennisque fusco-nigris, femeribus anterioribus fusco-testaceis. Long. -26. 
Texas and New Mexico. Smaller and broader than H. alternata, and dis- 
tinct from that as from all allied species in my collection, by the dark color of 
the under surface. The dorsal thoracic spot in one specimen is divided. 
H. p u r a, elongate-ovalis flavo-testaceus, labro, occipite, antennis tarsisque 
nigris, thorace latitudine sesqui breviere, lateribus late rotundatis, subtiliter 
punctulate, antice guttis duebus vel quatuor nigris ; elytris subtiliter rugosis et 
vix censpicue punctulatis, sutura vitta dorsali alteraque submarginali tennibus 
nigris. Long. -28 — "31. 
Colorado River, California. More slender than H. pluriligata Lec. and 
distinguished by the uniform yellow color of the under surface. 
H. foliacea, elengata subovalis, viridiaenea subnitida, thorace latitudine 
parum breviere, antrorsum angustato, subtiliter punctulata, linea transversa 
subtili postice inculpto, elytris punctulatis thorace parum latioribus. Long. 19, 
Texas, Mr. Haldeman. Closely allied in form and character to H. p u n c t i- 
p e n n i s Zi6c. (Beckwith's Expedition), but the thorax is less transverse and 
more densely punctulate, the posterior line is not more distinct at the middle 
than towards the side, and the elytra are more finely punctured. 
H. opulent a, oblonga convexa laete viridiaurea, capite antice rugose et 
punctate, postice laevi, thorace rude punctato, et parce punctulate, latitudine 
breviere, lateribus vix late rotundatis, angulis anticis oblique truncatis, disco
