184 A. R. Grote's Notes on the Zygsenidse of Cuba. 



them. Under side. — The palpi are white. — The Tongue is curled up 

 within them. The Breast is black, being spotted with white on its 

 side. The Abdomen likewise black, having one broad white ring on 

 it, and several narrow ones. The legs above and below these tufts are 

 white. All the wings are the same color as on the upper side. I re- 

 ceived it from the Bay of Honduras." 



From this description and the accompanying figure it is clear that C. 

 plumipes is a large dark species, with unicolorously dark wings, spot- 

 ted thorax and ringed abdomen, and without any yellow or orange 

 spots, which, as in C. pennipes, are described as characterizing Dr. 

 Clemens' Texan specimens. These then evidently form a third species 

 of the genus which may be called : 



Callicarus texanus. n. s. 



Euchromia plumipes, Clemens, (nee. Drury), Proe. A. N". S., Phil., p. 540. 

 (1800). 



"Blackish, somewhat tinged with blue. Antennae with ochreous 

 tips. Face yellow, with a blackish central stripe, and a yellow spot be- 

 tween the antennae. Thorax with four yellow spots, and tegular striped 

 with yellow on the inner edge. Abdomen, with tip dark-yellow, and 

 banded with the same hue between the segments; the two segments 

 next the basal banded with white beneath. Wings, concolorous dark- 

 brown, immaculate. The fore coxae each with an orange-yellow spot; 

 legs, black, middle femora striped with dark yellow; hind tibia? and 

 tarsi with yellow hairs, broadly banded at the end of each with black."

 Except in the immaculate wings, C. texanus is evidently broadly 

 distinct in every particular from C. plumipes, and differs in £he former 

 particular from C. pennipes, as well as by the yellow face, banded ab- 

 domen, etc., etc. No measurements are given by Dr. Clemens of his 

 specimens. Under the name "Euchromia" Group u Iloramia," a good 

 diagnosis is however given of the present genus — Callicarus, so that I 

 see that all these species are correctly associated. 



FOKMICULUS, n. g. 

 The antennae are massive, serrate and comparatively short. The ter- 

 minal articles appear slightly swelled, so that the antennae may be said 

 to be sub-capitate, terminating bluntly. Form exceedingly slight and 

 narrow. Head, free, small. Caputal tegument piceous, glabrous. In 

 neither of my specimens do I detect the presence of the labial palpi. 

 Maxillae, short. Legs, short, finely scaled; posterior pair hardly longer 

 than the rest, without tibial spurs.
