248 THE entomologist's record. 



pared to say, as I have no knowledge of the early larval stages of 

 this species. I have also a theory that E. vrr.sicolor forms a con- 

 necting link between Lasiocaiiipa and the SphingUlae, but as I have 

 nothing definite to go upon, I am not in a position to discuss the 

 matter now. 



Resemblances between Endromis versicolor and the Sphingides. 



Larva. — First Shin.- — (1) Caudal horn only faintly suggests that 

 of the Sphingides. It more nearly represents that of Lasiocawpa 

 qwrrifoliu. SernnrlSJ{in.—{2) Change in shape of head: Svicrinthus 

 {(irrllatua). (3) Dark medio-dorsal line : S. tiliae (in second skin). 

 (4) Oblique stripes : as in Hcda. (5) Strength of the 7th oblique as 

 compared with the others : Smerint/nix. In further support I would 

 point out that the oblique stripes are caused (in E. rersicolor) chiefly 

 by the absence of the shagreen tubercles on the stripes, and though in 

 Smrrinthns the reverse is the case with the stripes, the borders, at a 

 certain stage, are caused in the same way (i.e., by the absence of the 

 shagreen dots) . (6) The fact that the lateral lines are coloured, while 

 the oblique are due at first chiefly to structural arrangements : 

 Sj)ierinthux. (7) Small, thickly scattered shagreen tubercles, each 

 bearing one slightly clavate hair : Si)ieriutlius and Sj)/nn.r. Third 

 skin. — (8) Anal flap outlined with yellow : SmerintJius. (9) Darker 

 bordering to oblique stripes : Svicrintln(s { !" star/e). (10) Ventral and 

 anal prologs developed much after the manner of Smcrinthm (mentioned 

 by Buckler). TMst Statj,'. — (11) Retractile head when full-fed : 

 r/)r>(>r()rc7?»/)(/ c/^)r»(*/- (mentioned by Buckler). (12) Change of colour 

 before pupation : SpJdnx li/jiistri and .S'. tiliae (mentioned by Buckler). 

 (13) Only four stages in ontogeny (three moults) : X. pnpuli 

 (mentioned by Buckler). 



Pupa. — (14) Shape and general aspect approaches N. tiliae. 

 (15) Cremaster (in some characters) : .S. tiliae. (16) Movement in 

 cocoon. Pupa forces its way partly out : C. elpennr (Tutt and Buckler). 

 (17) Spines on free and following segments : ( '. elpenor. 



Imago. — (18) Shape of wings (rough only) : Smerinthus. (19) 

 Scheme of coloration (rough only) : S)nerinthns. (20) Discoidal 

 lunule on fore- wings (? too general to be of much use). 

 peculiarities and apparent differences. 



Larva. — (1) Colour of 1st stage. (2) Tubercles bearing more than 

 one hair (1st stage). (3) Habits (as a whole). (4) Colour of shagreen 

 tubercles (2nd stage). (5) Shape of head (2nd stage). (G) Additional 

 stripe on horn or hump of the 12th segment (best seen in last 

 stage). (7) Double row of black spots (dorsal) 2nd stage. 



Pupa. — (8) Bristles on anal armature: As in Satumia carjiini. 



Some Named Varieties in the Larentiidac. 



By LOUIS B. PEOUT, F.E.S. 

 As I am afraid we may have to wait some time before we get a work 

 dealing with the variation of the Geometrides on the lines of Tutt's 

 British Xoctuae,^' it has occurred to me that occasional unsystematic 



* I hope at some remote period to monograph my favovu'ite family, the 

 Lnrentiidae; but much preliminary study would of course be requisite, and I have 

 no desire to rush into the work. I take this opportunity, however, of appealing to 

 readers of the Record for any information of interest re the variation of species in 

 this family.
