Show 390 MR. G. R. CROTCH ON AZOREAN COLEOPTERA. [Mar. 28, stitiis fortiter seriatim punctatis, albido tessellatis; pygidio punctato. L. 1^-2 lin. cf . Antennis articulis 4 primis femoribusque rufis. 5 . Antennis 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 appear to belong to any of Schonherr's species, but comes in his Section I., with the femora dentate and thorax entire. The surface, on removing the pubescence, is closely sculptured all over, as is generally 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 punctato, macula alba ante scutellum; elytris maculis 4 denudatis striatis sat profunde transversim rugulosis; pedibus anticis tarsisque intermediis rufis; antennis nigris, articulis 5 primis rufis. L. If lin. cf . Tibiee intermedia; intus mox ante apicem dentatee. 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-picc-us; capite thoraceque creberrime punctatis, hoc subtiliter marginato, quadrato lateribus rotundato, angulis anticis productis acutis, basi leviter emarginato; scutello transverso, vix punctato elytris punctato-striatis, interstitiis crebre sed obsoletius punctatis; antennis pedibusque rufis. L. 6\-7 lin. This species belongs to the same type as the Madeiran H. vulcanus, 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 ( 6*), or short obliquely truncate ( $ ). XENOMMA MELANOCEPHALA, n. sp. X. rufo-piceum; capite et abdominis segmentis 2°-4m nigris cavite et thorace nitidis, vix punctulatis, hoc postice foveolato; elytris thorace dimidio brevioribus, sat fortiter granulatis; abdominee lavi, apicem versus latiore; antennis articulis transversis, ultimo maximo ; pedibus pallidis. L. 1 lin. Nearly allied to X.filiforme, Woll.,. from the Canaries, but anna rentlv distinct. >Ta" |
