count of other characters, and as the form of the labrum was 

 not referred to in my tabulation of Australian Sericoid 

 genera in placing Byrr/iomorpha, the fact now indicated that 

 that character is here (as in Heteronyx) not generic, will not 

 introduce confusion into the use of the tabulation. 

 B. anomala, sp. nov. Ovatus ; valde robusta ; valde convexa ; 

 subnitida; subglabra; nigro-picea, antennis palpisque ru- 

 fis; capite prothoraceque confertim rugulose sat fortiter 

 punctulatis; antennis 9-articulatis, flabello 4-articulato, 

 hujus laminis (exempli typici) articulis 2-5 conjunctis 

 longitudine sat aequalibus; labro sat porrecto sed haud 

 reflexo; clypeo profunde emarginato; prothorace quam 

 longiori ut 7 ad 4| latiori, antice fortiter angustato, 

 lateribus leviter arcuatis, angulis anticis acutis sat pro- 

 ductis posticis (superne visis) rectis extrorsum subpro- 

 ductis, basi marginata utrinque leviter sinuata ; scutello 

 magno basin versus punctulato ; elytris geminatim stria- 

 tis, sat fortiter rugulose punctulatis, infcerstitiis altemis 

 angustis sat laevibus ; pygidio fere ut pronotum punctu- 

 lato ; tibiis anticis extus tridentatis ; tarsorum posticorum 

 articulo basali quam 2"^ paullo breviori; coxis posticis 

 quam metasternum duplo brevioribus; segmento ventrali 

 apicali postice sinuato. Long., 6J 1.; lat., 3J 1. 

 This species is of more elongate form than its described 

 congeners, and differs notably from them both in the flabellum 

 of its antennae consisting of four laminae. The sculpture of the 

 elytra in this species resembles that of B. j)oncJerosa, Blackb. 

 except in the puncturation of the alternate (wide) interstices 

 being much closer and much less coarse. I believe the speci- 

 men before me to be a female, judging from the form of its 

 ventral segments. Among the comparatively few specim.ens 

 that I have seen of the genus I do not find any strongly-mark- 

 ed characters likely to be sexual, and it is possible that I have 

 seen only one sex.

The following table shov^^s distinctive characters of the 

 three species now known. 



A. Antennal flabellum consisting of only 

 three laminae. 

 B. All the elytral interstices decidedly, 

 and about equally, convex. Size 

 small ... ... ... ... .... verres, Blaclxh. 



BB. Only the alternate narrow inter- 

 stices of the elytra convex. Size 

 much larger ... ... ... ... ponderosa. Blachb. 



AA. Antennal flabellum consisting of four 



laminse ... ... ... ... ... anomala, Blackh. 



It will be well to add, here, a note that Scitala pallidnln, 

 Macl. (of which I have recently examined the type) might
