EURYLTCHNUS BLAGRAVII, Casteln.

In his note on this species, Mr. Bates says : — " If the male 

 prove to have the soles of the dilated joints of the anterior tarsi 

 furnished with a hair-pad, the species will belong to Eurylychnus, 

 from which it differs only in the elytra having a scutellar striole." 

 I took a number of specimens of both sexes under logs in the 

 brushes at Burrawang in Nov., 1890, and am able to state with 

 certainty that the male has no " hair-pad " on the lower side of 

 the joints of anterior tarsi. The tarsi are so much alike in both 

 sexes that I cannot determine the sex by their means ; neverthe- 

 less, I do not consider a new genus necessary for its reception. 

 So-called genera which rest on a single character of doubtful 

 value, appertaining to only one sex, seem to me too artificial for 

 practical workers in zoology ; though, no doubt, rigid cabinet 

 specialists may find them indispensable. 



This species has been very carefully described by M. Putzeys, 

 but to complete my notice of the genus Eurylychnus, I append 

 the following description founded on specimens from Burrawang. 



Form robust, convex. Black, legs reddish. Head large, with 

 strong transverse impression behind eyes ; frontal impressions 

 strong, curved, diverging backwards, widening internally at 

 clypeal suture, — this well marked, — a raised space between frontal 

 impressions and lateral channel on each side ; eyes round, promi- 

 nent. Labial palpi subsecuriform (broader in ^ than in 9). 

 Prothorax lightly convex, almost as long as broad (5 x 5|mm.), 

 very slightly emarginate in front, — the anterior angles being 

 broadly rounded and a very little advanced ; sides almost parallel 

 on anterior part to behind the middle, lightly rounded to anterior 

 angles, shortly narrowed behind ; lateral border narrow, reflexed, 

 shortly sinuate before base, thickened at the rather prominent 

 basal angles ; base sinuate ; median line lightly marked ; a short 

 strongly marked longitudinal fovea in front of each basal angle ;
