Scale of adult female elongate, narrow, flat, more or less distinct me- 

 dian carina; body of adult female elongate, thorax occupying nearly 

 three-fourths of length of body, metathoracic spiracles located near 

 middle of caudal half; pygidium with median pair of lobes contigu- 

 ous, two lobes together much broader than long, lateral margins 

 oblique, minutely serrate; plates near median lobes smaller than those 

 near cephalic end, arranged 0, 7, those of each lateris arranged 

 1-1-1-1-3; latadentis on each side between caudal first and second plates 

 and two between second and third; paraphyses club-shaped, short, ex- 

 tending to margin near lateral proximal angle of each median lobe; 

 dorsal oraceratubae wanting; lateres irregularly indented; anus ap- 

 proximately central in position. — Ceylon on Cinnamomum

SPECIES OF MARCHALASPIS 

 Pygidium with median pair of lobes distinct, entire, proximal portion 

 strongly constricted, distal portion broadly rounded; second and third 

 pairs of lobes incised, entire, lobelets subequal in size, similar in form, 

 proximal portion strongly constricted, distal portion truncately round- 

 ed; median, second, and third incisurae each with triangular projection 

 about as long as lobes, each identified as a plate; each lateris with 

 six or more lobe-like serrate projections; altaceratubae 9 on each 

 side; dorsal oraceratubae few, poorly developed and indistinct; anus 

 located midway between vulva and caudal margin. — Guinea on Copai- 

 fera. vuilleti Marchal. 



SPECIES OF CUPIDASPIS 

 Pygidium with median pair of lobes small, mere prominences, broadly 

 rounded, entire; second pair of lobes not incised, large, not project- 

 ing strongly, broadly rounded, entire; pectinae or plates wanting; 

 lateres with angular projections; altaceratubae prominent, five or six 

 on each side, one in each second incisura; anus large, six times its 

 width from caudal margin and over twice cephalad of vulva; breva- 

 ceratubae distinct, apparently third row with 4 oraceratubae, fourth 

 row with 5 mesal and 2 lateral oraceratubae. — California on Cupressus.
