NEOBROTICA AND RELATED GENERA — BLAKE 349 



median spine; pro thorax with a rounded depression on each side; pale 

 yellowish brown, the femora and front tibiae pale with a dark outer 

 streak, other tibiae and tarsi dark, lower surface dark, the elytra with 

 an irregular dark lateral vitta not reaching the apex and a sutural 

 vitta extending down to the middle, on each elytron three irregularly 

 shaped dark spots down the middle. 



Head with the interocular space more than half the width of the 

 head, occiput smoothly rounded, shining, impunctate, with a median 

 depression over the somewhat swollen frontal tubercles that are 

 marked by a depressed line only; in the male no carina but the lower 

 front scooped out in the middle into a bowl-like depression from which 

 protrudes a long thick spine; head entu'ely pale except for the brown- 

 ish tips of the jaws. No female known. Antennae not extending to 

 the middle of the elytra, yellowish brown becoming a little deeper in 

 color towards the end, in the male the third joint long and swollen 

 with a lateral long depression that divides it into a sort of upper and 

 lower lip, the lower one protruding at the end and united with an ex- 

 cavated and upwardly curved fourth joint, the remainder of the anten- 

 nal joints short, subequal and filiform. Prothorax somewhat rec- 

 tangular with only slightly curved sides and on the disc a rounded 

 depression on each side, surface slightly alutaceous, faintly shining, 

 impunctate, pale yellowish brown. Scutellum dark. Elytra with 

 faint traces of two or three raised lines, distinctly but not coarsely 

 punctate, the punctures tending to be striate and becoming less distinct 

 on the sides and at apex; pale yellow, each elytron with an irregularly 

 outlined lateral piceous vitta extending from the humerus to about the 

 apical curve but not reaching the apex or margin, a sutural vitta ex- 

 tending to the middle and three large irregularly shaped spots down 

 the middle, the apical one being subvittate and close to the suture. 

 Body beneath with neck, middle of prosternum, breast and abdomen 

 black, the anterior coxal cavities open, femora pale except a dark 

 outer streak, front tibiae of male with a dark outer streak, swollen, 

 and the first tarsal joint cylindrical, front tarsal joints pale, but the 

 middle and hind tibiae and tarsi entirely dark, middle and hind 

 tibiae with a short spine; claws appendiculate. Length 6.6 mm, 

 width 3.5 mm. 



Type, male, USNM 66837, from Zacapu, Michoacan, Mexico, 

 collected by J. J. MacKelvey, July 28, 1951. 



Remarks: This is closely related to Eccoptopsis cavifrons (Jacoby) 

 having a similar structure in the male antennae and the excavated 

 front of the head, and even the elytral dark markings although much 

 abbreviated appear to have the same general pattern as in cavifrons. 

 But the third antennal joint in the male is heavier and longer than 

 in cavifrons and slightly differently shaped.
