Of his var. 4i-punctata I have never seen an example ; of his var. 

 6-punctata I have seen many, and captured a characteristic specimen 

 with my hand in my garden as it was flying here (Lewisham) one 

 evening early in the present month of June. 



But the size of the spots (independently of the absence of some 

 of them) varies enormously, especially that between the antennae and 

 the pair immediately below (or before) the antennje, and all may be 

 reduced to mere points, or may be very large and conspicuous. In 

 some specimens from Switzerland (Meyringen and Sierre) the spots 

 are very large, and occasionally the sjwfs on the rjenae are connected with 

 the streaks on the clypeus, forming one enormous spot of irregular form. 



In the var. ^-punctata the spots are usually very small, reduced 

 to points ; and I am now of opinion that Ch. centralis, McLach., from 

 Turkestan, described by me in Fedtschenko's voyage, can be only 

 regarded as identical with Ch. 1 -punctata, var. ^-punctata. As my 

 original description of centralis was translated into, and published in, 

 Kussian (and, therefore, not to be understood, even by myself), I 

 append a copy of the note attached to the description from the original 

 MS. (which I fortunately preserved). ■ 



" The species is clearly allied to C. septempunctata, but differs in wanting the 

 black spots below the base of the antenna;, and in the small size of the other black 

 spots. It is also allied to the Japanese C. cognata, but that species has no spot 

 between the antennae. All may possibly be local modifications of C. septempunctata." 



I am not sure that I have seen typical Gh. T -punctata from 

 Turkestan, but the var. 6-punctata (centralis) has also been received 

 thence from another source, and is in Albarda's collection ; it may 

 probably be the dominant condition there. 



An example from Eastern Siberia, that I can only refer to Ch. 

 1 -punctata, has the spots on the genae virtually obsolete, but the other 

 spots conspicuous. 



It would appear that Ch. pallens, Rambur, described from a single 

 example from Spain, and now generally united with 7 -punctata, is really 

 of the var. ^-punctata, for Schneider says, " stria arcuata ante antennas 

 deficiente." Hagen makes no allusion to the spots in his notes on the 

 type in Stett. Zeitung, 18G6, pp. 298, 299. 



It is well to allude here to Ch. hipunctata, Burm., from Japan, 



and Ch. cognata, McLach., from Japan, China, and Cambodia. Accord- 



I ing to Schneider's detailed description of the type of hipunctata 



(Monogr., p. 104), the face should have seven spots as in 1 -punctata, 



\ the main difference being in the form of the spot below the basal joint 



of the antennae, which he defines by " stria arcuata," but the same
