390 MR. G. R. CROTCH ON AZOREAN COLEOPTERA. [Mar. 28, 



stitiis fortiter seriatim punctatis, albido tessellatis ; pygidio rugu- 

 lose punctata. L. H-2 lin. 



S . Antennis articulis 4 primis femoribusque rufis. 



5 . Anteimis pedibusque totis rufis. 



A pair of specimens, apparently male and female, were captured 

 in Santa Maria, on some flowers, by Mr. Brewer. It does not ap- 

 pear to belong to any of Schonherr's species, but comes in his Sec- 

 tion I., with the femora dentate and thorax entire. The surface, on 

 removing the pubescence, is closely sculptured all over, as is gene- 

 rally the case with this genus. I have dedicated this species to Mr. 

 Brewer, as a slight testimony to his exertions in procuring fresh 

 contributions to the Atlantic fauna. 



Bruchus azoricus, n, sp. 



B. niger, pube fusca dense vestitus ; thorace profunde punctata, 

 macula alba ante sculellum ; elytris macidis 4 denudatis striatis 

 sat profunde transversim rugulosis ; pedibus anticis tarsisque 

 intermediis rufis ; antennis nigris, articulis 5 primis rufis. L. 1^ 

 If lin. 

 J . Tibice intermedidE intus max ante apicem dentatce. 

 This species belongs to Schonherr's second section, having the 

 femora dentate and the sides of the thorax produced about the 

 middle into an abrupt tooth, but does not seem to accord with any 

 of those described in his work. 



Helops azoricus, n. sp. 



H. rufo-piccus; capite thoraceqxie creberrime punctatis, hoc subtiliter 

 marginato, quadrato latcrihus rotundato, angulis anticis productis 

 aciitis, busi leviter emarginato ; scutello transversa, vix punctata ; 

 elytris punctato-striatis, interstitiis crebre sed absaletius puncta- 

 tis ; antennis pedibusque rufis. L. 6^— 7 lin. 

 This species belongs to the same type as the Madeiran H. vul- 

 canus, Woll., but cannot, I think, be referred to that protean species. 

 The elytra have an abbreviated sutural stria, which is represented 

 more or less obsoletely by a series of punctures the whole length 

 of the suture. The male has the usual long antennae of the genus, 

 the joints keeping the same proportion, viz. first and second very 

 short, third nearly twice as long as the fourth, fourth to eighth 

 subequal, two last short, obconic, last ovate acuminate ( J ), or short, 

 obliquely truncate ( $ ). 



Xenomma melanocephala, n. sp. 



X. rufo-piceum ; capite et abdominis segmentis 2°-4"^ nigris, capite 

 et thorace nitidis, vix punctulatis, hoc postice fovealata ; elytris 

 thorace dimidio brevioribus, sat fortiter granvlatis ; abdomince 

 Icevi, apicem versus latiore ; antennis articulis transversis, ultimo 

 maxima; pedibus pallidis. L. 1 lin. 



Nearly allied to X. filiforme, Woll., from the Canaries, but appa- 

 rently distinct.
