242 NEUROPTERA. 
Taken in January (Gualan), February (Santa Lucia, San Pedro), April (Teapa), and 
July (Guadalajara, Frontera, Matachin, Cardenas 4), 
Of the Santa Lucia male Mr. Williamson noted, “In ravine, alighting on twig-tips 
and vegetation in sunny spots.” 
Having concluded that Misagria funerea® belonged here, I wrote to Prof. Carpenter, 
who kindly replied as follows :—“1Sept., 1904..... I have compared the type of my 
Misagria funerea with Cannaphila insularis (we have not C. angustipennis), and, as you 
say, the neuration agrees very closely. There is, however, a marked difference in the 
form of the abdomen, which is strongly constricted at the 4th segment in funerea, 
whereas in C. insularis it tapers gradually to the hinder end.” On sending one of the 
Ruatan Island males, listed under 0, infra, to Prot. Carpenter, he further wrote :— 
“10 Oct., 1904. Thanks for your letter and specimen of Cannaphila angustipennis, 
which I have compared with my type of Misagria funerea. I enclose a rough sketch 
of the front abdominal segments of the latter, by which you can see how markedly it 
differs from angustipennis. The constriction may be an individual aberration, but it is 
certainly not due to shrinkage or injury to the insect. In all other points the two are 
very close, but there is a slight difference in the form of the upper anal appendages: 
angustipennis has them more rounded toward the point, jfunerea more truncate (see 
the figure in my paper). I should say on the whole that the two are very close, but, 
if the form of abdomen be constant, they can hardly be cospecific. Cogeneric they 
certainly are, and, if angustipennis is really cogeneric with Kirby's C. insularis, my 
species is a Cannaphila. In form of abdomen, angustipennis is betwixt esularis and 
funerea.” | 
b. The following species agree with typical angustipennis, except that the labium is more or less marked with 
black. Proportions of the hind wings are given in Nos. 3-9 of the table on page 240. 
Dimensions.—Abdomen, ¢ 27-28, 9 28; hind wing, ¢ 30-34'5, 2 32 mm. 
Hab. Mexico, Teapa in Tabasco [1 ¢, labelled “Cannaphila angustipennis, Rambur,” 
in Prof. Karsch’s hand] (H. H. Smith); Guaremata, Gualan (Williamson, Deam, Hine, 
colls. Wiimsn., O. S. U.: 4 6,1 2); Honpvuras, Ruatan I. (Gaumer: 8 ¢ ). 
Taken in January (Gualan) and March (Teapa). 
None of these are young individuals, although they are not equally aged and the 
extent of the black marks on the labium is independent of the pruinosity on the body. 
They differ from the typical inswlaris in having the black spot on the labium smaller 
and not quadrangular and the hind wings a little narrower.
