present. The characteristic elongate shape of the adanal shields 

 with their slightly rounded angles is most distinctive after some 

 series have been examined. Variation in shape of the adanal 

 shields is illustrated (Figure 242). The basis capituli is some- 

 what variable in that the lateral margins may be more or less 

 angled, depending largely on the size of the individual. 



Females are similar to males in color and quality of puncta- 

 tions. The scutvun ha^ a distinctive outline (Figure 243) that 

 may be slightly more narrowly rounded posteriorly than the spec- 

 imen herein illustrated; it is as wide as or slightly wider than 

 long. The lateral grooves are frequently short or poorly defined; 

 the transition to the raised lateral border of the scutvtm may be 

 gradual or abrupt; the lateral grooves are often picked out by a 

 row of medium size punctations. The long cervical grooves that 

 extend, albeit shallow, to the posterior margin of the scutum 

 demarcate oval fields beside the central field, a characteristic 

 aspect of this species; combined vdth it is the moderate density 

 of small to moderate size punctations scattered over the scutum. 

 In small females, the punctations are frequently less numerous 

 and the scutal surface is not so markedly divided into a central 

 and two oval fields within a raised lateral border. The porose 

 areas vary with the size of the individual.
