Wenass Eiver to Fort Colville. I have, with great satisfaction, dedicated this beautiful 
species to Dr. Cooper, by whom it was collected, and to whose industry we are indebted for 
many important collections in Oregon. It belongs to the group (A—b) of my synopsis of 
Meloidae (Proc. Acad. 6, 334) near L. vulnerata. 
L. Gliildii, atra opaca, capite thoraceque parce punctatis, illo gutta verticali conspicus flavo, 
hoc latitudine longiore, lateribus antice rotundatis, elytris thorace sesqui latioribus scabris; 
antennis extrorsum crassioribus articulis rotundatis, ultimo plus duplo longiore acuminato ; 
tibiis posticis calcari externo crasso cylindrico. Long. *6— - 68. 
San Francisco, collected by Mr. J. Child, to whom I dedicate it as a slight memorial of the 
many valuable species made known by his scientific zeal. 
Nearly of the same form as L. nitidicollis Lee,, but, from its uniform black color, resembling 
L. moerens Lee. From the latter it differs by the thick cylindrical outer spur of the posterior 
tibiae ; the last joint of the antennae is longer than in either. 
Ditylus Fischer. 
D. quadricollis, ater subtiliter nigro-pubescens, confertim subtiliter punctulatus, thorace lati¬ 
tudine fere breviore subquadrato, postice subangustato, ad basin marginato truncato, ad apicem 
late rotundato, lateribus antice rotundatis, postice subobliquis; elytris thorace fere duplo latiori¬ 
bus lineis quatuor obsoletis elevatis. Long. -65.

Steilacoom, Dr. Suckley and Mr. Gibbs. The description first published by me was taken 
from a specimen in which, by injury, the thorax had been flattened so as to become square with 
parallel sides; but in tbe others since obtained the sides converge slightly behind, but not nearly 
so mueh so as in D. coeruleus. 
D. vestitus, ater subaenescens, pube fusca subsericea dense vestitus, capite thoraceque confer¬ 
tim subtiliter punctatis, illo linea verticali sublaevi, hoc latitudine longiore postice subangustato, 
ad basin marginato truncato, ad apicem late rotundato, lateribus ante medium rotundatis postice 
s ubsinuatis ; elytris thorace sesqui latioribus dense scabro-punctatis, lineis elevatis quatuor 
obsoletis. Long. ‘59. Tab. II, fig. 7. 
Shoalwater Bay, Dr. Cooper; one specimen. Remarkable by the dense brown pubescence 
with which it is covered ; the body is slender, as in D. gracilis , but the thorax has no discoidal 
impressions. 
Bruchus Linn. 
B. pauperculus, oblongus, ater, undique cinereo-pubescens, thorace antrorsum angustato, 
confertim punctato, elytris profunde striatis interstitiis planis. Long. '045—‘06. 
San Jose and San Diego, California. By the small size, entirely black color, and uniform 
pubescence, this is easily distinguished from all others known to me. 
Rhynchites Herbst. 
B. glastinus , elongatus niger, supra nigro-cyaneus, griseo-pilosellus, capite parce punctato, 
inter oculos sulcato, sulco antice furcato et ad rostri apicem fere extenso, occipite transversim
