 second are pale, the others are black. 



14. C. hi strio Er. Entom. 59 ; Mannerheim, Bull. Mosc. 1843, 247. 



California, unknown to me. This species rs very similar to 4-maculatus, but 

 the thorax is densely punctulate, and the posterior spot of the elytra reaches 

 the margin near the apex. 



Malachius Fabr. (emend. Er.) 



1. M. ae n e u s Fabr. Syst. El. 1, 306 ; Er. Entom. 66. 



Cambridge, Mass., Dr. Harris. Undoubtedly introduced, but apparently 

 naturalized, as one or two specimens occur every year. For the synonjma see 

 Erichson as cited above. The references relate only to the occurrence of the 

 insect ic Europe, and therefore should have no place in our fauna. 



2. M. a u r i t u s , cyaneo-niger, vix cinereo-pubescens, labri margine 

 clypeoque flavis, thorace vix transverse, angulis omnibus rotundatis, lateribus 

 anguste rubris, elytris subtiliter scabris, linea vix elevata notatis. Long. -23. 



San Francisco and San Jose, California. The male has the tips of the elytra 

 obliquely truncate and split, the inner part rising over the outer; in the female 

 the tip is not distorted, and is of a brilliant red Cvlor. The maxillary palpi are 

 short and subacute; the abdomen is entirely horny beneath. 



3. M. 1 o n g ic e p s , niger nitidus, breviter nigro-pilosellus, parce subtiliter 

 pubescens, capite elongato, thorace lateribus sanguineis rectis antice rotundatis, 

 elytris vix rugosis sutura apiceque sanguineis. Long. -15. 



A very singular species from San Diego, California. The head is twice as 

 long as wide, the antennae are inserted in from of the eyes, but not at the tip ; 

 they are strongly serrate in the male, and but moderately so in the female, the 

 last joint of the maxillary palpi is longer than the preceding, and acute. The 

 thorax is not wider than long. The elytra are dilated behind, and the tip is 

 entire in both sexes. The basal joints of the abdomen are membraneus in the 

 middle of their ventral surface. The anterior tarsi of the male have the two 

 basal joints slightly dilated. In this species the clypeus has a small mem- 

 branous spot anteriorly, similar to the ' rhinariurrC of some species of 

 Necrophorus. 



Anthocomus Er. 



1. A. Erichsonii. " ^. oft'o*?** Say." Er. Entom. 99. 



This species is unknown to me, it differs from the next species by having the 

 apex of the elytra of the male compressed ; the anterior tarsi are not dilated. 



2. A. otiosus. Malachius wtg-rtpenwi^HSay, Journ. Ac. 3, 184; Mala- 

 chius otiosus Say, Am. Eat. 3, pi. 48. Anthoconins atripennis Er. 108 (var. 

 with immaculate thorax.) 



Middle and Southern States. The male of this, as of all the following species 

 has the second joint of the anterior tarsi enlarged and produced above the 

 third and fourth joints ; the tip of the elytra is not compressed or distorted. The 

 anterior feet are usually yellow. 



3. A. rufifrons. Malachius r?//?/row5|Dej. Cat. 



Georgia ; from a specimen too mutilated for description this species seems 

 very similar to the last mentioned, but differs in the head being entirely rufous.
