GENERAL ORISMOLOGY. 25 



LITURA (litura), an indistinct spot, paler at its margins. 



PLAGA (plaga), a longish spot of irregular form. 



LINE (linea), a very slight, generally straight, but also sometimes 

 gently bent, differently coloured stripe. 



VITTA (viita), a broad longitudinal stripe. 



STRIGA (striga), a transverse band. 



FASCIA (fascia), a broad transverse band. 



ANNULET (aimulus), a narrow differently coloured circle upon a 

 surface, or upon the circumference of a part. 



LUNULET (lunulct), a half-moon shaped spot of a different colour. 



OCELLUS (ocellus}, a coloured ring, with a similarly or differently 

 coloured centre. In the latter case this point is called the PUPIL 

 (pupilla), and the space between it and the ring the IRIS. 



From these terms are derived the adjectives of a similar signification, 

 as Elytra vittala, &c. Besides these, many adjectives are used to 

 express similar, but less peculiar painting, such as, 



IRRORATE (irroratus), when a space is covered with the above 

 described atoms. 



NEBULOSE (nebulosus), when a surface has different, lighter and 

 darker and paler markings resembling the irregular colouring of a cloud. 



SIGNATE (signatus, or notatus), is a part with distinct markings. 



DISPERSED (adspersus, conspersus), when these markings consist of 

 small spots standing close together. 



FENESTRATE (Jenestratus), is a dark surface, with one or more 

 transparent spots. 



MARMORATE (marmoratus) , when the markings are variegated like 

 marble. 



TESTUDINATE (testudineatus), when the surface resembles the back 

 of a tortoise. 



UNDULATE (imdulatus), when the markings are waved either 

 longitudinally or transversely. 



UNICOLOR (wm'co/or), a part uniformly coloured. 



CONCOLOROUS (concolor), when resembling in colour to any other 

 part of the same insect. 



VERSICOLOURED (versicolor), when a part displays several different 

 colours, indeterminately restricted. 



DISCOLOURED (discolor), when the same part of an insect has diffe- 

 rent colours. (For example, legs are called discoloured when the anterior 

 are red and the posterior black.) 



IRIDICOLOR (iridicolor), a surface reflecting the prismatic hues.
