334 REVISION OF THE CICINDELIDiE OP AUSTRALIA, 



labial yellowish- white." The male has only the apical joint of 

 both labial and maxillary palpi black. Specimens from Cairns 

 vary from 13*5 {£) to 16 (5) mm. in length; they also vary in 

 pattern of the elytra (as shown in figs. 68, 69 and 70). Other 

 specimens received from Mr. French, as from North Queensland, 

 are equally large but have the posthumeral and humeral maculse 

 united. The legs vary in colour from all black (except trochanters 

 and an apical spot on four anterior femora) in a specimen (Q) 

 from Mr. French, ticketed " Endeavour River," to femora ferru- 

 ginous (except upper side, more particularly towards apex, 

 piceous-black); tibiae ferruginous with outer side infuscate in a 

 specimen (g) from Cairns. The colour of the legs is evidently of 

 slight importance in D. gruti. 



VarJ A. There remains a small form from Cairns in which the 

 colour of the upper surface is darker, the elytra without an 

 inner basal macula on each side of the scutellum, and with the 

 humeral macula extending backwards in a slender stripe (figs. 66, 

 67). Length 13-5 mm Q. Possibly this may represent a distinct 

 species, but more data than I possess would be required to form 

 a decided opinion on this point. It may be noted that var.A so 

 closely resembles D. volitans Macl., that it seems impossible to 

 separate these species except by the presence of the apical macula? 

 in D. volitans. 



I), parva Macleay, has more affinity to D. Jiavicans Chaud., 

 than to any other species. Labrum testaceous with a narrow 

 lateral margin; metasternum in male testaceous, in female 

 piceous in middle with sides testaceous; palpi pallid, apical joints 

 in female piceous, in male hardly infuscate just at apex. 



Genus Nickerlea. 



NlCKERLEA DISTYPSIDEROIDES Horn, 



From Dr. Horn's Latin diagnosis of this species I take the 

 following excerpts : — 



" Differt a Distyp&idera flavicante Chaud., labro paullo breviore, 

 antice latius truncato et in parte centrali antica dentibus 3 (non 

 dente una; perparvis (vix percipiendis) ornato : dentibus 2
