c?. Head 2.5 mm. across eyes, concave and striolate between eyes; occiput 

 transversely rugulose; labrum large, median part porreet, parallel on sides, with 

 three subequal prominent teeth, a short seta on each side of apical tooth, incision 

 between second and third teeth deep, narrow, asetose, posterior tooth prominent, 

 placed just before middle of length, emargination before it bearing a short seta. 

 Prothorax as long as broad (1.5 x 1.5 mm.) ; disc strongly convex, slightly 

 rugulose. Elytra much wider than prothorax (4.5 x 2.5 mm.) ; puncturation 

 very strong and rather uneven. Length 7-9, breadth 2.5-2.7 mm. 



Hah. — North West Australia : Wyndham and Forrest River. Several 

 specimens were sent to me by Mr. John Clark of Perth, Western Australia. 



Allied to C. ohloncficollis Macl.. of which C. tenuicollis Macl., is considered 

 by Dr. W. Horn to be a red form. From C. leai SI., to which it is closely 

 allied, it differs by size larger, labrum with median apical part more prominent, 

 all the teeth and the notches between them more strongly developed, labial palpi 

 with penultimate joint longer and not so thick, more setose; prothorax with 

 middle part more convex, transverse impressions deeper; elytra with apical 

 white spots larger, extending along the whole leng-th of the apical margin, but 

 separated from one another at the suture; abdomen with a lateral white stripe 

 of setae along the sides of segments 1-4 (In C. leai there are only four or five 

 separate white setae on the side of the basal segment). From C. tenuicollis 

 Macl., it differs even more markedly than from C. leai by size large; labrum 

 larger and with apical median part more prominent; white spots of elytra larger. 

 The wide continuous lateral stripe on each side of ventral segments 1-4 is also 

 a conspicuous difference. In C. tenuicollis there are (from a damaged specimen 

 in my collection) a few white setae on the sides of segments 1 and 2. 



CiCINDELA RAFPLESIA Cliaudoir. 



Specimens in my collection (c?, 9) from Carnarvon differ from specimens 

 from northern Queensland by having the metallic parts of the pattern cuiJreous, 

 not viridaeneous ; and by having the four anterior trochanters each with a fixed 

 seta, not only the trochanters of the fore-legs. In these characters I have not 

 found any variation amongst the eastern specimens which I have been able to 

 examine, but the eastern and western specimens are certainly conspecific, though 

 it has yet to be discovered whether the range of C. rafflesia is continuous from 

 Cape York Peninsula to Carnarvon. 



Notes. 



(1). In 1915 Dr. Walther Horn published the third part of his magnificent 

 monograph of the family Cicindelidae*. In this masterly work Dr. Horn records 

 all the Cicindelidae of the world known to 1915 (including all species, and sub- 

 species, with their sj-nonymy) ; he gives tables of the tribes, subtribes, and 

 genera, but not of the species. In part iii. he deals with the subtribe Cicindelina 

 (three genera, viz., Cicindela with about 595 species, and about 260 chief races, 

 Eurymorpha and Apteroessa with 1 species each. He uses the genus Cicindela 

 in its widest sense (including in it 29 synonyms and 13 "groups" which various 

 author's have thought worthy of distinct names), and to render it less diflBcuIt 

 to make out the species of this immense genus he treats the species of each
