42. I\eocollyris aptera, Lund. 



Cicindela aptera, Lund, Skrivt. Nat. Selsk. i, 1790, p. 65, pi. 6, fig. 1; 

 Fabricius, Ent. Syst. i, 1792, p. 169 ; Chaudoir, Ann. Soc. Ent. 

 France, 1864, p. 518, pi. 8, fig. 15. 



Very closely allied to A 7 , smith i, but easily known by its smaller 

 size, narrower form, and more slender pronotum, which has the 

 pronotal collum longer and much less abrupt, and shows more 

 distinct traces of strigose sculpture ; the elytra are cylindrical and 

 parallel-sided, castaneous, with the central portion more or less 

 dark, almost smooth towards base and apex, very strongly plicate, 

 with a narrow bright reddish band just at the centre (often obso- 

 lete) ; episterna of metasternum distinctly punctured over the 

 greater part of their surface ; femora red, anterior and inter- 

 mediate tibiae black, posterior tibiae black, testaceous at apex, 

 tarsi (except apex) testaceous. 



Length 19-20 millim. 



Assam : JNaga Hills, N. Manipur, Sylhet ; Tenasserim. 



The punctation is somewhat variable, but the shape of the pro- 

 notum will easily distinguish it from the preceding species ; the 

 female specimen I have before me has the pronotum a little more 

 dilated at the sides, the elytra less parallel, and the punctuation of 

 the base and apex of the latter more distinct. The species is 

 very rare apparently, and comparatively few specimens are known. 

 The elytra are not connate, as stated by Fabricius, nor is the 

 species wingless.

Allied to A 7 , aptera, but with the head smaller, the eyes a little 

 less prominent, the forehead narrower anteriorly between the 

 sulci, the pronotum a little shorter, the anterior margin more 

 declivous, and the posterior portion less conical and more abruptly 

 constricted in front ; the pronotum is longer and more slender 

 than in A 7 , smithi, and the elytra much as in that species, but with 

 the central plicate portion more dilated, especially toward base, 

 and less abruptly passing into scanty punctuation, the punctures 

 before and behind the plicae being larger ; the metasternum is also 

 more thickly aud finely punctured. The antennae are less thick- 

 ened than in A 7 , orichalcina, with which it agrees in the shape of 

 the head, and the pronotum is longer and more slender, with a 

 longer and narrower pronotal collum ; the sculpture of the elytra, 

 moreover, is different, being less close behind, with the punctures 

 not elongate. 



Length 20 millim.
