San Diego, on the open ocean shore, June; abundant. The variety with immaculate 
elytra is about as numerous as the type: the only intermediate form I have observed is 
a specimen in which the marginal spots and the terminal lunule are all small, while the 
middle band and posterior discoidal spot are of the normal size. Baron Chaudoir men- 
tions that “in this species we find the Mexican type C. decostigma Chevr. (mexicana [Klug,) 
and flavopunctata Chevr., from which it is very distinct; the former also inhabits Cali- 
fornia.” 
With this opinion of my learned correspondent, notwithstanding the resemblance in 
the form of the thorax, I cannot entirely agree. The arrangement of the spots of the ely- 
tra proves that the relations are rather with C. rufiventris, Hentzii, &. than with C. de- 
costigma: C. flavopunctata (which is really C. mexicana A/ug,) has one character of the 
present group, in the abdomen being partly red, but to produce a similarity of spots, we 
must obliterate the terminal lunule, replace the discoidal by a submarginal spot, and de- 
stroy the marginal spot behind the oblique medial fascia. 
50. C. Hentzii, fusco atra, capite thoraceque vix zeneo-variegatis subtiliter granulatis, illo utrinque striolato, hoc 
parum rugoso subcylindrico, lateribus paulo rotundatis, elytris punctatis, postice rotundatis, subtiliter serrulatis, 
lunula humerali seepe interrupta, fascia obliqua ante medium extrorsum cum linea marginali brevi coherente, ma- 
cula marginali pone medium, lunulaque apicali antice cum macula discoidali connexa albis; subtus cyaneo-viridis 
ad latera albo-pilosa, abdomine toto rufo. Long. -42—-48. 
Mas elytris fere parallelis; femina elytris postice paulo latioribus.

Massachusetts, Dr. Harris. Precisely similar in form and sculpture to the next two 
species, and indeed so closely connected with them that the three might properly be con- 
sidered as races of one species. In this, however, the colour is almost black, the two dots 
of the humeral lunule are connected at the margin; the middle band reaches the margin 
and is dilated into a short line, which extends forwards; the marginal spot behind the me-
