Pupa of Dicaehis elongatus, Dej. 



The larva undergoes its transformation during the day-time, 

 and the pupa is entirely white, 10 mm. long, and presents very 

 little worthy Of special mention. The la brum is of an elongate 

 triangular form and extends to the tips of the mandibles, and is 

 apparently composed of two parts, a transverse basal portion 

 which is the true labrum, and the. triangular apex which disap- 

 pears with the pupa skin. The palpi are also very elongate ami 

 the ligula prolonged. ■•' 



After six days the eyes of the pupa become dark, then the 

 mouthparts brown, and after ten days the imago develops fully. 



It remains tw r o days white, and becomes black at. the end of the 

 twelfth day. 



Larva found. Transf. into pupa. Imago developed.

Larva of Dicaelus politus. 



So closely resembling. that of Dicaelus elongatus, that I can see 

 no differences, except that the antennae and legs are dark, nearly 

 black. 



Pupa also very similar. 



I found a specimen Aug. 25th, that transformed into pupa Aug. 

 30th, and the imago developed Sept. 7th. 



Two other similar larva died. 



The larva of Dicaelus dilatatus is, while young, grayish-black 

 above, and somewhat lighter gray beneath so that the seven black 

 marks of the ventral segments are visible only by close inspection. 

 -By growing larger, thi&gray changes into white. 



F. G. SCHAUPP. 



During my stay in Fla. I observed that the larvae of Catocala 

 fratercula, G.&R. (C. atarah, Strecker) live on live oak, remain 

 in pupa state two weeks; the larvae of ultronia Guen. live on wild 

 cherry. Of C. Sappho Strecker I collected fifteen specimens ; the 

 first appeared at the end of April. 



Cicihdela marginata Fab. was found near a creek on a mea- 

 dow, end of June, C. gratiosa Guer. six miles south of Tallahassee 

 in pine woods, end of May rare, and common in June, intermingled 

 with C. abdoramalis Fab. ana ^anctulata Fab.
