230 Variation in the Meahvorm, Tenebrio molitor 



b. Segmental Anomalies. 



The number of segments of which the larval body is built up amounts 

 to twelve, besides the head. Of these segments two or more may be 

 partially fused in various manners. Rather than describe each case 

 apart I refer to Fig. 2 (Nos. 1 — 25), where these fusions are represented 

 in diagram.
