MADEIRAN COLEOPTERA, ; 61 
The A. munda, so well distinguished by the rufescent hue of its 
head and prothorax, the latter of which has a deep, central, trans- 
verse impression at its base (the impression being terminated at 
either extremity by a short raised costa, or ridge), was detected by 
myself in Madeira proper, during June1855, in the Circo at 8. Antonio 
da Serra. The Madeiran specimens would appear to be a little more 
deeply punctured than the ordinary European ones. 
168. Atomaria apicalis*. 
A, ovata subconvexa fusco-picea valde pubescens nitida profunde 
punctata, elytris ad apicem necnon ad humeros dilutioribus, an- 
tennis brevibus robustis ferrugineis, pedibus testaceis. 
Long. corp. lin. 3. 
Atomaria apicalis, Erich., Nat. der Ins. Deutsch. iii. 895 (1848). 
, Woll., Rev. Brit. Atom., Trans. Ent, Soc, Lond. iv. (New 
Series) 78 (1857). 
A, ovate, being widest about the middle, and a good deal acuminated 
both before and behind (especially the latter), more convex than 
the last species, brownish-piceous, coarsely pubescent, shining, 
and very deeply punctured. Prothoraw widest about the middle, 
and with the sides almost equally (though slghtly) rounded ; 
delicately margined along its lateral edges, and more distinctly so 
along its hinder one (which is a little sinuated, and slightly raised 
in the centre) than is the case in the A. munda. Elytra more or 
less diluted in colouring towards their apex, and obscurely so at 
either shoulder. Antenne short, robust, and ferruginous, Legs 
testaceous. 


A single specimen of the common European A. apicalis (which 
however is a little more deeply punctured in Madeira, and somewhat 
less acuminated both before and behind, than in more northern lati- 
tudes, and has also its antenne a trifle shorter, and its prothorax 
just perceptibly more rounded at the sides) was captured, by myself, 
about halfway up the Boa Ventura, in the north of Madeira proper, 
during August 1855. 
§ IL. Corpus apterum: prothorax postice fere immarginatus. 
(Species valde indigenee. ) 
169. Atomaria insecta, n. sp. 
A. oblongo-ovata convexa rufo-picea subpubescens nitidissima leviter 
punctata, prothorace amplo convexo, elytris ad basin plus minus 
rufo-castaneis, ad apicem vix dilutioribus, antennis pedibusque 
longis gracilibus, illis fusco-nigris basi rufo-ferrugineis, his rufo- 
testaceis, femoribus tibiisque infuscatis. 
Variat (immaturus) colore omnino dilutiore.
