DELTOCEPHALUS NORMANI. 63 



" The genital valve of the male very widely rounded, 

 about half as long as the preceding segment." 



Edwards gives, as a habitat, " One example, taken 

 August, 1887 ; Coxford Heath, Norfolk." He notes 

 that it has nothing in common with D. coronifer of 

 Marshall, except as to the pattern on the forehead. 



Size, 0'14 inch, or 3*55 millimetres. 



Deltocephalus Normani, Scott. Plate LI., fig. 3. 

 Edw. pt. ii. p. 55. 



Considerable doubts may be expressed as to the 

 propriety of admitting this insect to be distinct from 

 D. striatus, or perhaps from D. repletus. Practically no 

 important points of difference appear in the diagnosis 

 of Mr. Edwards' Synopsis ; who notes also its similarity 

 to -D. striatus, and records the meagre capture (by 

 Mr. Geo. Norman) " of one male and two females on 

 high heathery land in Morayshire." 



Dr. Piffard kindly lent me a specimen labelled D. 

 Normani, but it hardly agrees with the diagnosis given 

 by Scott. Indeed, in its appearance it less recalls 

 to me the form of D. striatus than that of D. repletus. 

 I have introduced a figure of Dr. Piffard's insect into 

 my plate for comparison with D. coroniceps. In its 

 spotted fore legs it resembles the species I have just 

 before described, with which, however, it cannot be well 

 confounded. The elytral areas are inwardly bordered 

 with fine dark lines, without being suffused with 

 fuscous-brown. 



Size of Dr. Piffard's insect, O'll inch, or 2'79 milli- 

 metres.
