AMERICAN LEPIDOPTERA. 23 



SYNOPSIS NOCTUIDARUM HTJCUSQUE IN CALIFORNIA REPERTARUM. 



BY HERMAN BEHR, M. D. 

 Hypena Califomica, Behr. 



H. rostrali similis sed raargine exterior! alarum antiearum magis repanda 

 apiceque acuto. Linea mediana exterior stricta, nullo mode undulata vel re- 

 panda, prope marginem posticam dente extus verso aucta. Signaturae reliquae 

 maxiine variabiles interdum fere obsoletse. 



Larva Isete viridis Plusiiforrais in Urtica gracili pascens. 

 Kather common near San Francisco. 



AGASSIZIA, Behr. 

 Genus maxime singulare, inter Boletohiayn et Xylioden Gn. intermedium, dif- 

 fert a Boletohia conformatione palporum, qui cum palpis Xi/liodis a eel Guenee 

 descriptis omnino congruunt. A. xyliode longe distat et forma alarum et vena- 

 rum distributione qua cum Boletohia fere convenit, sed tamen non congruit. 

 Quum vero specimina perpauca quaj possideo squamis d'enudare non ausus sim 

 venarum fabricam exacte describere nolui, dum copia speciiuinum denudare et 

 destruere permittat. 



2. A. TIrbicola, Behr. 



Alfe omnes sericese fusese violaceo micantes, linea duplice brunnea repandius- 

 cula divisse. Alarum antiearum pars costalis brunneo punctata, initia linearum 

 ordinariarum indieans. Subtus alas omnes dilutee fere coneolores. 



Three specimens in my collection from different parts of California. 

 One specimen captured in a warehouse in San Francisco. 



The larva of this interesting little insect is not known. As the lar- 

 vae of Boletohia cai-boHaria, the only one in this most anomalous group 

 that we are acquainted with, is found to feed on fungi and wood in a 

 certain state of decomposition, I venture the opinion that a similar 

 mode of living might be that of our Ayassizia. 



Two other specimens of an equally paradoxical interest were col- 

 lected by Baron Terloot in the Sierra Madre, between Mazatlan and 

 Durango, and are congeners, if it is allowable to draw conclusions from 

 specimens that are not perfect in all essential parts. 



3. Capnodes Califomica, Behr. 



Alae omnes pallide straminese. Alarum antiearum linese medianse simplices 

 et umbra mediana subfuscse. Umbra marginalis per lineam submarginalem 

 undulatam pallidam transversa. Macula fusca, semilunaris in loco maculae 

 reniforrais. Alse gpsticse et cunctse subtus fere ut alse anticse supra signatse. 



Size of Ephyra Omnicronarin, to which Geomitride it also bears a 

 striking analogy in its general appearance. It is, at present, the only 

 representative of this tropical genus in our State. One specimen from 

 Downieville. 



4. Erebus Odora. Linn. 



This well known and far spread species has been found also in Cali- 

 fornia, in whose southern portion, perhaps, it will prove as common as 

 in the adjacent parts of Mexico.
