Speeies of the American Genus Astylus. 349 



Head rather small ; antennae short in both sexes. Prothorax 

 transverse, rounded at the sides. Elytra moderately long, 

 without costse ; the apices, <£ ? , rather narrow, rounded, 

 feebly denticulate. 



J . Ventral segment 5 deeply arcuato-emarginate, 6 sub- 

 conical, moderately long. 



Length SJpfc, breadth 2J-2J mm. ( tf ? .) 



Hab. Ecuador (Rosenberg). 



One pair. Smaller than A. bourgeoisie Kirsch ( = biss7x- 

 guttatus, Gorh.), the head narrower, the antefiiise much 

 shorter, the elytral markings very different, the six orange- 

 yellow spots (one of which is not visible from above) 

 precisely similar in the two specimens seen. The male, 

 not dissected, doubtless has a bilobed tegmen. 



15. Astylus sexguttatus. 



Astylus sexguttatus, Kirscli, Abbandl. Zool. Mus. Dresden, 1888-89, 

 no. 4, p. 11, t. 1. fig. 20. 



$ . Ventral segment 5 broadly, semicircularly emarginate, 

 6 grooved down the middle. Tegmen with long, narrowly 

 separated, rather broad lobes, which are ciliate at the tip. 

 Penis-sheath attenuate,- the apical portion beyond the aperture 

 narrow. 



Hab. COLOMBIA, Popayan and Jambalo (sec. Kirsch). 



There is a $ of this species in the Museum received in 

 1855, labelled with the MS. name .A. bimaculatus, Clit., and 

 as from Guatemala, the locality being certainly incorrect. 

 A brilliant, nigro-cseruleous insect, with six sharply defined 

 flavorts spots on each elytron, arranged 1, 2, 2, 1. A. mi- 

 chaelisi, Pic (1908), from Theiesopolis, Brazil, seems to be 

 more nearly allied to A. sexguttatus than to A. sexmaculutus, 

 Perty, with which it is compared by its describe);. 



16. Astylus luteoguttatus, sp. n. 



Moderately elongate, narrow and subparallel-sided (<$), or 

 broader (? ), shining, pilose, the hairs on the under surface 

 and legs cinereous; greenish-aeneous, the elytra and ventral 

 surface often nigro-casruleous, the latter with a spot at the 

 base, two others along the sides (the anterior one sometimes 

 obsolete), another, transverse, before the apex, and sometimes 

 two additional spots along the disc near the suture orange- 

 yellow or rufous, the basal joints of the antennas rufo- 

 maculate ; sparsely, finely, the elytra moderately coarsely 

 punctate. Head rather narrow, well developed behind the
