[February, 



obvious ; it has a meaning, and undoubtedly should not be altered so as to give 

 it a different meaning, either for the sake of uniformity of termination (!) or for 

 any other reason whatsoever, unless it can be shown to have been previously 

 occupied. 



1. M. m u r i n a, sriseo-olivacea, dense sericeo-pubescens, thorace elliptico, 

 capite fere latiore, elytris striatis, antennarum articulo ultimo longiore. Long. 

 18.

Dirccea murina Fabr. Syst. El. 2, 91. 



Middle and Southern States ; common. Body covered with very dense serice- 

 ous yellowish hair. Head finely punctured, slightly convex, narrowed behind the 

 eyes, and subtruncate : mouth and oral organs yellow. Antennae with the sec- 

 ond joint scarcely longer than the third : the following to the 8th are equal ; 9th 

 and 10th fuscous, pale at the tip, nearly as long as the two preceding united: thorax 

 very little wider than the head, one half longer than wide, elliptical, margined 

 posteriorly, finely scabrous. Elytra striate with fine punctures : interstices very 

 finely scabrous. Legs varying from yellow to piceous ; the anterior pair usually 

 paler. The male has the 5th segment of the abdomen truncate, whereby the 

 6th becomes visible. In the female the 2nd segment is impressed transversely 

 each side. In both sexes the first segment is conspicuously longer. 



2. M. confusa, atra minus dense cinereo-pubescens, thorace elongato-ovato, 

 capite non latiore, elytris vix seriat impunctatis, antennarum articulis 3 ultimis 

 elongatis subaequalibus. Long. 18. 



Two males. Georgia. Darker colored than the preceding, with less dense 

 pubescence. Head finely and sparsely punctured, rounded posteriorly, with the 

 occipital impression longer than in M. murina. Mouth and its organs yellow ; 

 antennee with the 2nd joint scarcely shorter than the 3rd, 37 equal, 8th fuscous, 

 a little shorter than the 7th ; 9 11 fuscous, nearly twice as long as the 7th and 

 Sth united, nearly equal, the 11th being a little longer. Thorax densely sca- 

 brous, not wider than the head, nearly twice as long as wide, disc subelliptical, 

 a little narrowed behind, where it is margined. Elytra with punctures arranged 

 in indistinct series, interstices scarcely scabrous or punctured. Feet piceous; 

 base of anterior thighs rufous. First segment of abdomen hardly elongated. 



The discovery of this second species within our territory seems to confirm 

 the opinion of Ferte, that M. linearis Neivman, (Entom. Mag. 4, 377,) is dis- 

 tinct from M. murina, though the great carelessness with which Newman's de- 

 scriptions were made, should prevent us from placing reliance on them, in the 

 absence of any corroborating circumstances. Newman's figure does not show 

 the very strong basal margin of the thorax which exists in all the species of the 

 genus, and where a character so evident has been omitted, we are prepared to 

 expect any inaccuracy whatever, both in the outline and details of the figure.
