Species of the Ameriain Genus Astylus. 345 



divided, with a small, deep, friaDgular notch at the tip. Te<i- 

 nieii with rather broad, lonii-, lateral lobes, which are angiilai'ly 

 dilated at the apex within, the apices clothed with black hairs. 

 Penis-sheath almost straight from near the base, abruptly 

 narrowed at the tip, the narrow apical portion slightly 

 thickened distally. 



? . Ventral segment 6 simple, about as long as 5. 



Hub. Ecuador (BucJcIej/), Oliillalocha, Fioja (Bourr/eois), 

 San Lucas, Quito {iw co//. i^///), ?Gn;iyacjuil {[iosenherg) ; 

 Peru, .Taeu de Bracamoiras [Httmhollt awl Bonj'laud), 

 Moyabamb;i [ex coll. Frij), Nnuta ; BOLIVIA. 



To judge from the labels on the numerous examples before 

 me, two or more species are confused in collections under the 

 name A. bon//hmdi, after tiie elimination of A. ruhripennis ; 

 and it is doubtful if much reliance can be placed on some of 

 the Ecuador locality tickets, as it is scarcely likely that an 

 insect ranges from the sea-level at Guayaquil to the elevated 

 region of Quito. A moderately large, black, thickly nigro- 

 pilose * form ; the elytra red, with a common scuteliar patch, 

 an oblong ])atch at the shoulder (these markings sometimes 

 cojilescent ))osteriorly), two transversely-placed s{)ots at tlie 

 middle of the disc (often confluent and reaciiiiig the suture), 

 a large spot below tliein, the sutural and apical margins, and 

 the outer margin in part, bh\ck. In one or two exain[)lfts 

 the upper surface has a faint metallic tinge. 



10. Astylus cceruleotinctus, sp. n. 



Modeiately elongate, shining, nigio-pilose ; nigro-cseru- 

 leous, sometimes with a greenish lustre, the basal joints of 

 the antennae rufo-maculate ; the elytra with an oval, jioste- 

 riorly acuminate spot at the base, two tratisversely-placed 

 patches before the middle (the inner one subtriangular or 

 oval, and sometimes coalescent with the basal spot, the outer 

 one extending forward along the outer margin to tiie shoulder), 

 and a large, anteriorly subtruncate, complete or incomplete 

 aniiulus before the a))ex, flavescent or red. Head small, 

 somewhat deeply inserted into the prothorax, closely, finely 

 punctate, hollowed in the middle between the ejes, the hitter 

 not very prominent; antennae moderately long in (^, shorter 

 in $ . Prothorax transverse, finely punctured, the maro-ins 

 strongly reflexed. Elytra rather broad, roundetl at the apex, 

 closely, Somewhat coarsely punctate, sometimes with a faint 

 costa on the inner part of the disc. Legs slender.
