Mr. F. P. Pascoc on some Australian Colydiida}. 467 



costseform ; body beneath light yellowish brown, rather finely punctured, 

 with the anterior margins of the abdominal segments dark brown ; 

 eyes black. Length 2 lines. 



The single and very slightly curved impression on the prothorax 

 is sufficiently distinctive of this species. 



Botlirideres versutus. 



B, rufo-fuscus, vix nitidus ; prothoraco longitudinaliter corrugato, postice 

 linea cm-vata inipresso, basi late sulcato ; elytris coucoloribus, interstitiis 

 alternis puuctatis. 



Hah. Melbourne. 



lieddish brown, scarcely shining ; head corrugated, especially in fi'ont, 

 punctured behind the eyes ; prothorax nearly equal in length and 

 breadth, slightly contracted at the base, the anterior angles prominent, 

 covered with coarse oblong punctures throwing the intervals into small 

 longitudinal folds, the impressed line at the base semicircular, having 

 a smooth space in front, and a shallow, broad groove behind ; elytra 

 coarsely striate, the alternate interstices, commencing at the sutural 

 one, with a veiy obvious line of punctm-es, the three lateral costsiefonn, 

 the striae appai'eutly impimctate ; body beneath reddish brown, shining, 

 coarsely punctured, the punctures on the abdominal segments gradually 

 more crowded as they approach the last. Length 2\ lines. 



Perhaps most nearly allied to the last on account of its corrugated 

 prothorax, with its single impressed line, which, however, is deeper 

 and more decidedly curved ; the coloiu- is also different, and the punc- 

 tures on the alternate interstices are less marked. 



Penthellspa secuta. 



P. fusco-picea; prothorace obsolete biimpresso, angulis posticis rotim- 

 datis ; elytris puuctato-striatis, lateribus a basi sensini angustatis. 



Hub. Melbourne. 



Dark pitchy ; head and prothorax coarsely and somewhat closely 

 punctm'ed, the latter rather longer than broad, very, slightly incurved 

 at the sides, and rounded at the posterior angle, the disk with two very 

 shallow, almost obsolete, longitudinal impressions; scutellum broadly 

 transverse ; elj'tra coarsely striate-pimctate, very gradually receding 

 from the base to the apex ; body beneath pitchy, with rather distant 

 punctures ; antennae and legs reddish ferruginous, shining. Length 

 2 lines. 



Very like Penihelispa porosa (a Rio insect), but darker, rather 

 loss depressed, and more strongly punctured, especially on the pro- 

 thorax, which has also its posterior angles more roimded.
