ART. 6. NEW SPECIES OF TERMITES SNYDER. < 



NEOTERMES CASTANEUS Burmeister. 



Dedlated adult. — Head castaneous-brown, darker anteriorly espe- 

 pecially at sides of depression, longer than broad, depression between 

 epicranial suture, lines of suture not visible as in N. angustoculus 

 Snyder, with scattered short hairs, trace of round frontal gland de- 

 pression. Compound eye black, large, projecting, not round, sepa- 

 rated from lateral margin of head by a distance less than its diameter,^ 

 less than two diameters from posterior margin. Ocellus hyaline, 

 large, obliquely inward from but very close to eye. 



Labrum light yellow-brown, widest at middle, nearly truncate on 

 tip, with long hairs. 



Post-clypeus yellow, broader than long. 



Antennae yellow-brown, 16 (20?) segments, pubescent; third seg- 

 ment slightly modified, clavate, darker colored, longer than second 

 or fourth- 



Pronotum paler than head, much broader than head, not twice as 

 broad as long (length measured to corners where high) and shorter 

 than wing scale, not very deeply emarginate anteriorly, sides nar- 

 rowed slightly posteriorly, slightly emarginate posteriorly, with short 

 hairs. 



Abdomen dorsally same color as pronotum with short hairs. 



Legs yellow-brown, tibiae darker, slender, pubescent. 



Measurements .^Length of entire dealated adult, 8.5-9.5 mm.; 

 length of head (to tip labrum), 2.1 mm.; length of pronotum, 1.35- 

 1.45 mm.; length of hind tibia, 1.6 mm.; length of wing scale, 1.45 

 mm.; diameter of eye, 0.45-0.50 mm.; width of head, 1.85-1.90 mm.; 

 width of pronotum, 2-2.15 mm. 



Soldiers were not collected with these adults, but Mr. Banks states 

 (Banks and Snyder, 1920 ^) that there is variation in the soldiers of 

 N. castaneus Burmeister; I believe, however, two species are repre- 

 sented — N. castaneus and N. angustoculus. It is probable that the 

 soldier of N. castaneus is the form with mandibles short and stout, 

 with blunt points, being not nearly as long as the width of the head; 

 head shorter than in N. angustoculus Snyder, pronotum not so nar- 

 rowed behind. However, this may be variation within the species, 



Dealated adults distinct from angustoculus by the very large eye, 

 long pronotum, trace of round frontal gland depression (absent in 

 castaneus) and short hairs. However, close to connexus Snyder but 

 has short pubescence. 



^ This distance is greater in iV. angustoculus Snyder and this difference was noted by N. Banks in Antil- 

 lean Isoptera, Bull. Mus. Comp. Zoology, vol. 57, No. 10, p. 477, pi. 1, fig. 10, January, 1919; he believed 

 that there were two forms of castaneus.
