Hob. : Hedjaz (Millingen), a small series varyiuji' a good deal in 

 size, but not in other respects. 



The aedeagus (fig. 36) differs but little from that of H. frifanus 

 q.v. It is slightly smaller and the lateral lobes perhaps straighter 

 externally. 



15. — Helophorus ivfelix, sp. n. 



Sat convexus, nigcr, elytris brunneis, capite thoracequc obscure metallcsccntibus, 

 palpis, atitennis pedibusqiie rufis ; thorace obsolete granulato, latera rersws palli- 

 diore; elytris fortiter punctatis, interstitiis angustis sat convexis. Long. 2f mm. 



Palpi moderately long, terminal joint a little thickened, not black at the 

 tip. Thorax distinctly emarginate beliind the eye, short, the sides but little 

 rounded, middle groove rather large, median interval distinctly angulate 

 externally, sub-median groove rather broad, lateral margin very little set out, 

 flavescent; the sculpture an effaced granulation. Elytra rather short and 

 convex, punctures large, as broad as the intervals. On the under-surface the 

 flanks of the elytra are visible. 



Hab.: Hedjaz (Millingen). 



Though I liave seen only one specimen there can be no doubt it is a 

 species closely allied to H. ardbicus, but distinct, being narrower, less 

 convex, and with the thorax a little different in form, colour and 

 sculpture. Though probably a male, I have not ventured to examine 

 the aedeagus. 



16.— Helophorus spinifer, sp. n. 



Augustus, subparallehis, parum convexus, capite thoraceque nigro-submetallicis, 

 elytris testaceo-obscuris, antennis, palpis pedib^lsque testaceis ; fortiter sciUpturatus , 

 Long. 2\, lat. 1 mm. 



Hab. : Eussia or. (Orenburg, Faust) . 



A very distinct little insect, distinguished by its small size, narrow, parallel- 

 sided form, and slight convexity, with rather coarse sculpture, and the quite 

 visible flanks of the elytra (fig. 71). The surface of the thorax is granulate 

 even on the median intervals, the sub-median groove is only very slightly 

 sinuous, and the lateral margin is fine, with very little trace of any yellow 

 colour. The punctui-es of the elytra are large, and the interstices naiTOw ; 

 there is a slight post-basal depression, and the dark yellow, or brown, colour is 

 very little variegate. The legs are slender. Wings long, slightly tinged with 

 yellow. 



I received three specimens from the late Herr J. Faust, of Libau, 

 as No. 52, labelled " H. gramdaris vel sp. n." They are in a rather 

 decayed state so that the natural colour of the elytra is a little doubtful. 

 There is no nearly allied species known to me ; the aedeagus (fig. 37)
