posteriorly, dorsal punetures four modenitoly impressed, the posterior puncture 

 more distant than the others ; elytra a little wider than the thorax, slightly wider 

 posteriorly, a little longer than wide conjointly, very slightly longer than the 

 thorax, punctuation coarse, not densely placed ; abdomen iridescent, punctuation 

 very sparse and very much finer than on the elytra, beneath punctured as above. 

 Length .20— .24 inch: 5—6 mm. 



Male. — Anterior tarsi slender: last ventral segment with a broad but shallow 

 eraargination, bordered by a pellucid membrane. 



Female. — Tarsi slender: last ventral entire. 



This species is probably identical with a specimen 9 loaned me by 

 Mr. Fauvel with the name Schioarzi. Considering the material insuffi- 

 cient I passed it by, having used the name for a more imposing species. 

 As will be observed by the sexual characters the species belongs to series 

 D (ante p. 206), and to the quadripunctate division, and is most closely 

 related to distans i\nd fallaciosus. In these two species the dorsal punc- 

 tures of the thorax are arranged with the first puncture more distant, 

 notably so in di.<?fans, less in the other. In the present species the ar- 

 rangement is reversed, the posterior puncture being more distant. By 

 its sexual characters inversus is more allied to distans, but the last ven- 

 tral S has no longitudinal impression. 



I have two anomalous female specimens, one .of them has fhree dorsal 

 jHUR'tures on each side, the second hanfi.ve on one side and/b»v on the other.

The species have, by the foregoing pages, been greatly increased in 

 number beyond those now in our lists ; many are here described as new, 

 while a number have been recognized as identical with those of the 

 I'astoni hemisphere.
