LASIOCAMPIDAE 



DicOGASTER CORONADA Barnes. 



The receipt of two Lasiocampid larvae feeding on oak from Para- 

 dise, Ariz., which we succeeded in breeding through into the 3 and 

 9 of the above species proves that our description of the larva pub- 

 Hshed in the revision (Contr. I, (2), p. 16, 1911) was erroneous; 

 the larval notes published under coronada should possibly be referred 

 to Quadrina diacoma Grt. which appears to occur in the same gen- 

 eral locality but of this we have no definite knowledge. We offer 

 the following description of the true coronada larva. 



Head large, blackish, brown at the extreme sides with white cen- 

 tral line and white clypeus with central dark line; three outcurved 

 white lines on each cheek; whole head covered with long brownish 

 hairs. Body broad and rather flat with strongly developed lateral 

 tubercles on anterior segments, very similar to those found in Tolype 

 larvae; clothed with sparse rather short deep brown hairs shading 

 into white laterally; color deep velvety black-brown with very faint 

 pale dorsal stripe ; prothoracic shield largely whitish ; posterior margin 

 of segments rather broadly whitish narrowing laterally ; a broken pale 

 ochreous supra-spiracular stripe consisting of two distinct portions 

 on each segment, an anterior straight short stripe and a posterior 

 larger oblique patch situated directly above the spiracle which is pale 

 with a faint light patch below it. Each abdominal segment is sub- 

 divided into four subsegments, the fourth one containing subdorsally 

 two minute orange dots on each side ; anal plate whitish ; legs reddish ; 

 prolegs pale, tinged with pink; under side pale whitish ochreous. 

 Breadth of head 7 mm. Length at rest 70 mm. Width, 12 mm. 



Tolype lowriei sp. nov. (PI. XX, Figs. 10, 11). 



Palpi black at sides; front white with an admixture of black hairs; 

 thorax pure white, the tufting deep brown, heaviest on metathorax, the an- 

 terior portion often covered by the white thoracic hairs ; abdomen light blue- 

 gray dorsally, shading into white laterally; primaries white, banded with light 

 blue-gray with the veins outlined in white; basal area gray-shaded followed 

 by an upright band of white, enclosing a narrow gray line ; median band gray, 

 the inner edge straight, the outer slightly angled below costa gently concave 

 between veins 4 and 6 and then practically straight to inner margin ; follow- 

 ing the median band is a prominent broad white area bounded outwardly by
