NOTES ON SOME HAWAIIAN CARABID^. 



BY THE EEV. T. BLACKBUEN, M.A. 



A\"ith reference to the observations of Dr. Sharp on the genera 

 of Hawaiian Carahida in the Eut. Mo. Mag. (Yol. xx, p. 218), I have 

 to make the following remarks : — 



Atrachycnemis. — A re-examination of this genus satisfies me that 

 it is better placed in the Ancliomenini where Dr. Sharp places it than in 

 the HarpalidcB, though I still consider that it has more than a superfi- 

 cial relation to that family. AVhen I originally referred it to the Har- 

 \palidcB, it was with considerable hesitation, as it seemed to me to occupy 

 |a somewhat intermediate position, having the anterior tarsi in the male, 

 at least (if I possess both sexes there is little difference) , and the anten- 

 nae more or less Harpaliform. The former have the first four joints, 

 though small, very wide and short, the 4th joint being fully as wide as 

 ' I the 3rd ; the latter have the 3rd joint very evidently more strongly pu- 

 llbescent than the 2nd. The anterior tibiae, however (and the tarsi in 

 I some respects), are so decidedly Anchomeniform, while the pubescence 

 (^ and porosity of the 3rd joint of the antennae are so evidently less than 

 [jof the 4th, that T admit Atrac'hycnemis may be rightly placed in the 

 A' Ancliomenini, w^hile still believing that its analogies with the HarpaUdcB 

 "'iare real. My specimens are without any pronotal setae. 



}■ Anchomenus muscicola, mihi (included, I presume, by Dr. Sharp 



in his genus Metromenus) , has a single systematic seta on either side 



,of the pronotum, about the middle of the lateral margin — accidentally 



lie! removed I suppose from Dr. Sharp's specimens, for the absence of 



''"^fpronotal setae figures among the characters of the genus. I have two 



or three specimens in which it is conspicuously present on both sides, 



p. and several in which it is present on one side only ; in the rest it is 



ra'ji' evident that the seta has been accidentally removed on both sides, but 



iin every specimen I can detect under a moderate power the minute 



^*[jfcubercles from which the setae spring. 



Mauna, nov. gen. 



It is necessary to add another generic name to those already 



oined for the Hawaiian AncJiomenini. This name is required for the 



entfi^jinsect hitherto called Blaclchurninfrigida, mihi, but several times stated 



by me (Ent. Mo. Mag., vol. xv, p. 120 ; vol. xvi, p. 106) to be placed in 



^'^'^^the genus Blachhurnia only provisionally, and with much hesitation. 



After reading Dr. Sharp's paper on the genera of Hawaiian Garabidce 



(referred to above), with which 1 heartily agree, I see the impossibility
